本発明は、調光体に駆動電力を供給する給電機構に関する。 The present invention relates to a power supply mechanism that supplies driving power to a light control body.
電気的制御によって光の透過、散乱を切り換える事が可能な調光体は、車両、船舶といった移動体および建築物の窓ガラスに使用され、室内外の視認性などを制御するために使用されている。 Light control bodies, which can switch between light transmission and scattering through electrical control, are used in the window glass of moving objects such as vehicles and ships, as well as buildings, and are used to control indoor and outdoor visibility. There is.
調光体は通常、一対の透明基板上に設けられた透明電極に液晶材料が挟持された構成であり、透明電極に印加する駆動電圧を印加する事によって駆動される。
透明電極に駆動電圧を供給する役割を果たすのが給電機構である。
給電機構は、透明電極に駆動電圧を供給する電気配線と、電気配線を透明電極に接続する給電部と、から構成されている。A light control body usually has a structure in which a liquid crystal material is sandwiched between transparent electrodes provided on a pair of transparent substrates, and is driven by applying a driving voltage to the transparent electrodes.
The power supply mechanism plays the role of supplying a driving voltage to the transparent electrode.
The power feeding mechanism includes electrical wiring that supplies a drive voltage to the transparent electrode, and a power feeding section that connects the electrical wiring to the transparent electrode.
給電部としては、通常、透明電極に電気配線を接触させた状態で固定する導電性テープや導電性ペーストなどが使用されている。 As the power supply part, a conductive tape, a conductive paste, or the like, which fixes electrical wiring in contact with a transparent electrode, is usually used.
一方、調光フィルムなどの調光体は、建築物や車両の窓など、太陽光に晒される過酷な環境の下で使用される事が多い。その為、その様な環境下での信頼性の保証が求められる。その様な信頼性は、調光体の本体だけでなく、調光体全体として求められるものである為、調光体の電極と外部電源からの配線を接続する部分である給電機構に対しても求められている。 On the other hand, light control bodies such as light control films are often used in harsh environments where they are exposed to sunlight, such as in buildings and vehicle windows. Therefore, it is required to guarantee reliability under such an environment. Such reliability is required not only for the main body of the dimmer, but also for the entire dimmer, so the power supply mechanism, which is the part that connects the electrodes of the dimmer and the wiring from the external power source, must be is also in demand.
給電機構の信頼性を確保する為、従来は給電機構を形成した後、金属膜付きの粘着部材を給電機構の上から手作業で貼合する方法が行なわれていた。
しかしながら、この方式では金属膜付きの粘着部材を貼合する位置精度を確保する事が容易ではなかった。
また、近年、調光体の給電部は設置するガラスの美装性の観点から、限りなく狭く、また小さくする事が求められている。その為、粘着部材を狭く、小さな領域に手作業で貼合する方法は、位置精度の点でますます困難になって来ているため、生産性が低下しており、工程負荷が増大している。In order to ensure the reliability of the power supply mechanism, a conventional method has been to form the power supply mechanism and then manually attach an adhesive member with a metal film over the power supply mechanism.
However, with this method, it is not easy to ensure positional accuracy for laminating the adhesive member with a metal film.
Furthermore, in recent years, the power supply section of a light control body has been required to be made as narrow and as small as possible from the viewpoint of aesthetics of the installed glass. For this reason, the method of manually pasting adhesive materials in narrow, small areas is becoming increasingly difficult in terms of positional accuracy, reducing productivity and increasing process load. There is.
この様な問題点を解決する技術に類似する先行技術としては、特許文献１には、給電線、特に、給電線基端部の振動などによる劣化や作業ミスなどによる損傷を防止でき、よって、給電線基端部における積層体接合面のすきまの発生を防ぎ、給電線および積層体の耐久性、防水性を向上させ、作業効率を向上させることができるコネクタが開示されている。また、特許文献２は、狭いスペース内に光学素子を収める端子構造が開示されている。また、特許文献３には、透明導電膜と電極構造との接合強度を向上させた調光体が開示されている。 As a prior art similar to a technique for solving such problems, Patent Document 1 discloses that it is possible to prevent deterioration of the power supply line, especially the base end of the power supply line, due to vibrations and damage caused by work errors, etc. A connector is disclosed that can prevent the generation of a gap between the bonding surfaces of the laminate at the base end of the feeder, improve the durability and waterproofness of the feeder and the laminate, and improve work efficiency. Further, Patent Document 2 discloses a terminal structure that accommodates an optical element within a narrow space. Further, Patent Document 3 discloses a light control body with improved bonding strength between a transparent conductive film and an electrode structure.
しかしながら、これらの先行技術は、太陽光下などの過酷な屋外環境に長時間晒されても、調光体の給電機構の信頼性を確保することを配慮した技術ではない。 However, these prior art technologies do not take into consideration ensuring the reliability of the power supply mechanism of the light control body even if it is exposed to a harsh outdoor environment such as sunlight for a long time.
上記の事情に鑑み、本発明は、高い耐候性に基づく長期の信頼性を備え、且つ狭くて小さな領域であっても高い位置精度で形成可能な給電機構を提供する事を課題とする。 In view of the above circumstances, an object of the present invention is to provide a power feeding mechanism that has long-term reliability based on high weather resistance and can be formed with high positional accuracy even in a narrow and small area.
上記の課題を解決する手段として、本発明は、透明基材の表面に透明導電層を備えた一対の基板の透明導電層を内側にして調光層を挟持した調光体に駆動電圧を給電する給電機構であって、

前記転写部は、
接着剤層と、
前記接着剤層上に設けられた紫外線遮光層と、を備える給電機構である。As a means for solving the above problems, the present invention supplies a driving voltage to a light control body that has a light control layer sandwiched between a pair of substrates having a transparent conductive layer on the surface of a transparent base material, with the transparent conductive layer on the inside. A power feeding mechanism,
comprising a joint part and a transfer part located so as to cover the joint part,

the transparent conductive layer;
a conductive adhesive layer;
a power supply member electrically connected to the transparent conductive layer via the conductive adhesive layer,

The power feeding mechanism includes an ultraviolet light shielding layer provided on the adhesive layer.
また、本発明は、前記透明基材の融点と、前記導電性接着剤の硬化温度と、前記接着剤の硬化温度と、が（透明基材の融点）＞（導電性接着剤層の接着剤の硬化温度）≧（接着剤層の接着剤）なる関係を満たす事を特徴とする。 Further, the present invention provides a method in which the melting point of the transparent base material, the curing temperature of the conductive adhesive, and the curing temperature of the adhesive are such that (melting point of the transparent base material)>(adhesive of the conductive adhesive layer) It is characterized by satisfying the relationship: curing temperature of adhesive layer) ≧ (adhesive of adhesive layer).
また、本発明は、前記紫外線遮光層が、金属薄膜からなる事を特徴とする。 Further, the present invention is characterized in that the ultraviolet light shielding layer is made of a metal thin film.
また、本発明は、基材フィルムの上に、剥離層と、紫外線遮光層および接着剤層からなる転写層と、をこの順に備えている事を特徴とする転写層転写フィルムである。 Further, the present invention is a transfer layer transfer film characterized in that it comprises a release layer, a transfer layer consisting of an ultraviolet light shielding layer and an adhesive layer in this order on a base film.
また、本発明は、透明基材の表面に透明導電層を備えた一対の基板の透明導電層を内側にして調光層を挟持した調光体において、双方の基板の端部に上記給電機構を備えている事を特徴とする調光体である。 Further, the present invention provides a light control body in which a light control layer is sandwiched between a pair of substrates having a transparent conductive layer on the surface of the transparent base material with the transparent conductive layer inside, and the above-mentioned power supply mechanism is provided at the end of both substrates. It is a light control body characterized by being equipped with.
本発明の給電機構によれば、調光体の透明導電層と外部電源からの配線である給電部材を、導電性接着剤層を介して接着した接合部を、接着剤層で被覆した上に紫外線遮光層を備えている。その為、長時間、太陽光下などの屋外環境に晒されても、接着剤層と導電性接着剤層とが、紫外線などによる劣化を防ぐ事ができる耐候性を備えている。その事から長期に亘る信頼性を確保する事ができる。
また、本発明の給電機構は、熱転写によって、接着剤層とその上に形成された紫外線遮光層を形成する為、狭い部分に高い位置精度で形成する事が可能である。According to the power supply mechanism of the present invention, the transparent conductive layer of the light control body and the power supply member, which is the wiring from the external power source, are bonded together via a conductive adhesive layer, and the joint is covered with an adhesive layer and then Equipped with a UV blocking layer. Therefore, even if exposed to an outdoor environment such as sunlight for a long time, the adhesive layer and the conductive adhesive layer have weather resistance that can prevent deterioration due to ultraviolet rays and the like. As a result, long-term reliability can be ensured.
Furthermore, since the power feeding mechanism of the present invention forms the adhesive layer and the ultraviolet light shielding layer formed thereon by thermal transfer, it is possible to form the adhesive layer in a narrow area with high positional accuracy.
＜給電機構＞
本発明の給電機構について、図１を用いて説明する。
本発明の給電機構１０は、透明基材１の表面に透明導電層２を備えた一対の基板８の透明導電層２を内側にして調光層３を挟持した調光体２０に駆動電圧を供給する給電機構１０である。<Power supply mechanism>
The power feeding mechanism of the present invention will be explained using FIG. 1.
The power supply mechanism 10 of the present invention applies a driving voltage to a light control body 20 that has a light control layer 3 sandwiched between a pair of substrates 8 having a transparent conductive layer 2 on the surface of a transparent base material 1 with the transparent conductive layer 2 on the inside. This is a power feeding mechanism 10 that supplies power.
本発明の給電機構１０は、上記の基板８の端部において、透明導電層２と、導電性接着剤層４と、駆動電圧を伝える給電部材５と、をこの順に備えた接合部９と、接合部９を被覆する様に転写された転写層１４と、をこの順に備えている。 The power supply mechanism 10 of the present invention includes, at the end of the substrate 8, a junction 9 including, in this order, a transparent conductive layer 2, a conductive adhesive layer 4, and a power supply member 5 for transmitting a driving voltage; A transfer layer 14 that is transferred to cover the joint portion 9 is provided in this order.
転写層１４は、接着剤層６と、接着剤層６の上に備えられた紫外線遮光層７と、をこの順に備えている事が特徴である。 The transfer layer 14 is characterized in that it includes an adhesive layer 6 and an ultraviolet light shielding layer 7 provided on the adhesive layer 6 in this order.
給電機構１０は、駆動電圧の発生装置から給電部材５を通して伝えられる駆動電圧を、透明導電層２を介して調光層３に伝達する、給電部材５と透明導電層２との接合部９を提供するものであるが、本発明においては、更にその接合部９を紫外線から保護する機能を備えているため、屋外に長時間晒されても、劣化し難い為、長時間の信頼性を確保する事が可能となる。 The power supply mechanism 10 includes a joint 9 between the power supply member 5 and the transparent conductive layer 2, which transmits the drive voltage transmitted from the drive voltage generator through the power supply member 5 to the light control layer 3 via the transparent conductive layer 2. However, in the present invention, the joint part 9 is further provided with a function of protecting it from ultraviolet rays, so even if it is exposed outdoors for a long time, it is unlikely to deteriorate, thus ensuring long-term reliability. It becomes possible to do so.
また、透明基材１の融点と、導電性接着剤層４の接着剤の硬化温度と、接着剤層６の接着剤の硬化温度と、が下記の式を満たす事が好ましい。
（透明基材１の融点）＞（導電性接着剤層４の接着剤の硬化温度）≧（接着剤層６の接着剤）
この様な関係にある事で、透明基材１が溶融しない温度範囲で、導電性接着剤層４の接着剤と、接着剤層６の接着剤と、を熱硬化させる事が可能となる。また、接着剤層６が最も低温で硬化する事により、最も低温で接合部９の周囲を硬化させることができる。Further, it is preferable that the melting point of the transparent substrate 1, the curing temperature of the adhesive of the conductive adhesive layer 4, and the curing temperature of the adhesive of the adhesive layer 6 satisfy the following formula.
(Melting point of transparent base material 1)>(curing temperature of adhesive of conductive adhesive layer 4)≧(adhesive of adhesive layer 6)
With such a relationship, it becomes possible to thermally cure the adhesive of the conductive adhesive layer 4 and the adhesive of the adhesive layer 6 in a temperature range in which the transparent base material 1 does not melt. Further, since the adhesive layer 6 is cured at the lowest temperature, the area around the joint portion 9 can be cured at the lowest temperature.
また、紫外線遮光層７が、金属薄膜であっても良い。金属膜は密度が高い為、薄い薄膜であっても紫外線遮光機能が高い為である。紫外線遮光層７を薄くする事により、紫外線遮光層７の破断が容易となり、転写層１４の転写を容易にする事ができる。 Moreover, the ultraviolet light shielding layer 7 may be a metal thin film. This is because the metal film has a high density, so even a thin film has a high UV blocking function. By making the ultraviolet light shielding layer 7 thinner, the ultraviolet light shielding layer 7 can be easily broken, and the transfer layer 14 can be easily transferred.
（透明基材）
透明基材１は、透明性および耐熱性を有するプラスチックフィルムであれば特に限定されない。好ましくは、ポリエステルフィルム、シクロオレフィンポリマー系フィルム、ポリカーボネートフィルムなどを挙げる事ができる。
透明基材１の厚さは、１６μｍ～１０００μｍである事が好ましい。１６μｍ未満であるとハンドリングが困難になる為、品質の維持が難しくなる。また１０００μｍを超えるとフレキシブル性が失われる事によりハンドリング性が悪くなる。また、透明性が落ちる。(transparent base material)
The transparent base material 1 is not particularly limited as long as it is a plastic film having transparency and heat resistance. Preferred examples include polyester film, cycloolefin polymer film, and polycarbonate film.
The thickness of the transparent base material 1 is preferably 16 μm to 1000 μm. If it is less than 16 μm, handling becomes difficult, making it difficult to maintain quality. Moreover, if it exceeds 1000 μm, flexibility is lost and handling properties become worse. It also reduces transparency.
（透明導電層）
透明導電層２は、透明性が維持できる範囲であれば特に限定されない。ここで、透明性とは、表面抵抗率が２０００Ω／ｓｑ（スクエア）で、全光透過率が７０％以上である事を指す。全光透過率が７０％未満であると、調光体を透明状態で使用する際に曇りが感じられ、散乱時との差異が低減する。その為、調光体としての機能が良好ではなくなる。また、表面抵抗率が２０００Ω／ｓｑを超えると、透明導電層２の抵抗が大きくなり過ぎる為、調光体への均一な電圧の給電が困難となる。その為、調光体の駆動に支障をきたす他、発熱などの危険を生じる虞がある。
具体的な材料としては、ＩＴＯ（Ｉｎｄｉｕｍ Ｔｉｎ Ｏｘｉｄｅ）、ＩＺＯ（Ｉｎｄｉｕｍ Ｚｉｎｃ Ｏｘｉｄｅ）等の無機材料およびＰＥＤＯＴ（ＰｏｌｙＥｔｈｙｌｅｎｅ ＤｉｏｘｙＴｈｉｏｐｈｅｎｅ）等の有機材料を挙げる事ができるが、いずれを
用いても構わない。
膜厚については、１μｍ以下である事が好ましい。１μｍを超えると、透明基材１への追従性が劣る様になり、ハンドリング時に透明導電層２が損傷を受け、亀裂などによる導電不良を招く虞がある。また、高価な材料の使用量が増加する事にもなる。(transparent conductive layer)
The transparent conductive layer 2 is not particularly limited as long as its transparency can be maintained. Here, transparency refers to a surface resistivity of 2000 Ω/sq (square) and a total light transmittance of 70% or more. If the total light transmittance is less than 70%, cloudiness will be felt when the light control body is used in a transparent state, and the difference between it and when it is scattered will be reduced. Therefore, the function as a light control body becomes poor. Furthermore, if the surface resistivity exceeds 2000 Ω/sq, the resistance of the transparent conductive layer 2 becomes too large, making it difficult to supply a uniform voltage to the light control body. Therefore, in addition to interfering with the driving of the light control body, there is a possibility that danger such as heat generation may occur.
Specific materials include inorganic materials such as ITO (Indium Tin Oxide) and IZO (Indium Zinc Oxide), and organic materials such as PEDOT (PolyEthylene DioxyThiophene), but any of them may be used.
The film thickness is preferably 1 μm or less. If it exceeds 1 μm, the followability to the transparent base material 1 will be poor, and the transparent conductive layer 2 may be damaged during handling, leading to poor conductivity due to cracks or the like. Moreover, the amount of expensive materials used will also increase.
（導電性接着剤層）
導電性接着剤層４は、導電部材と熱硬化性樹脂からなる。熱硬化性樹脂としては、接着性を併せ持つ樹脂である事が好ましい。(Conductive adhesive layer)
The conductive adhesive layer 4 is made of a conductive member and a thermosetting resin. The thermosetting resin is preferably a resin that also has adhesive properties.
導電部材としては、金、銀、銅、錫、パラジウム、ニッケルなどの金属や、それらの金属の合金で被覆された樹脂製粒子が一般的であるが、表面層が導電性を有する微粒子からなる材料であれば、如何なる形状であっても良く、如何なる材料であっても良い。また、導電特性が異方性を備えた材料であっても、異方性を備えていない材料であっても良い。 As conductive members, resin particles coated with metals such as gold, silver, copper, tin, palladium, nickel, or alloys of these metals are common, but the surface layer is made of fine particles with conductivity. As long as it is made of any material, it may have any shape and may be made of any material. Furthermore, the material may be a material with anisotropic conductive properties or a material without anisotropic conductivity.
熱硬化性樹脂としては、常温で液状または粘性状を示し、２５０℃以下の加熱により流動性、粘性、タック性を失い、固化するものが好適である。固化するのに２５０℃を超える加熱が必要な樹脂である場合、透明基材１の融点を超える事があり、透明基材１との熱圧着時に、透明基材１が変形などの損傷を受ける虞がある。 The thermosetting resin is preferably one that is liquid or viscous at room temperature, loses fluidity, viscosity, and tackiness and solidifies when heated to 250° C. or lower. If the resin requires heating above 250°C to solidify, the melting point of the transparent base material 1 may be exceeded, and the transparent base material 1 may be damaged such as deformation during thermocompression bonding with the transparent base material 1. There is a possibility.
熱硬化性樹脂としては、エポキシ系樹脂やアクリル系樹脂を好適に使用する事ができる。また、熱硬化を促進する硬化剤を含有している事が好ましいが、自己反応性、自己架橋性により硬化させる事でも良い。 As the thermosetting resin, epoxy resins and acrylic resins can be suitably used. Further, it is preferable to contain a curing agent that promotes thermal curing, but it is also possible to use self-reactivity and self-crosslinking to effect curing.
導電性接着剤層４の厚さは、１μｍ～５０μｍである事が好ましい。１μｍ未満であると給電部材５の表面に形成されている凹凸に追従できずに通電不良を招く虞がある。５０μｍを超える場合は、厚過ぎる事により、熱圧着の際に導電性接着剤層４の全体に亘って加熱する事ができず、樹脂の熱硬化が不十分となる部分ができる事により、接着性不良となる虞が出てくる。また、高価な材料の使用量が増加してしまう。 The thickness of the conductive adhesive layer 4 is preferably 1 μm to 50 μm. If it is less than 1 μm, it may not be possible to follow the unevenness formed on the surface of the power supply member 5, which may result in poor conduction. If it exceeds 50 μm, it is too thick and the entire conductive adhesive layer 4 cannot be heated during thermocompression bonding, resulting in areas where the resin is insufficiently thermoset. There is a risk of becoming sexually impaired. Moreover, the amount of expensive materials used increases.
（給電部材）
給電部材５としては、銅やアルミニウムなどの通電を行える材料からなり、少なくとも透明導電層２との接続を行う部分が舌片状や短冊状となっている部材であれば好適に使用することができる。その他の部分の形態は如何なるものであっても構わない。例えば、銅箔をポリイミド樹脂で被覆し、接続に使用する部分だけポリイミド樹脂を除去したＦＰＣ（Ｆｌｅｘｉｂｌｅ Ｐｒｉｎｎｔｅｄ Ｃｉｒｃｕｉｔｓ、フレキシブルプリント配線板）を挙げる事ができる。(Power supply member)
The power supply member 5 is preferably made of a material that can conduct electricity, such as copper or aluminum, and is preferably a member in which at least the portion that connects to the transparent conductive layer 2 is tongue-shaped or strip-shaped. can. The other parts may have any form. An example of this is FPC (Flexible Printed Circuits) in which copper foil is coated with polyimide resin and the polyimide resin is removed only in the portions used for connection.
（転写層）
転写層１４は、接着剤層６の上に紫外線遮光層７が形成されている層である。後ほど説明する転写層転写フィルム１３を使用して、給電機構１０の接合部９の上から、接着剤層６と紫外線遮光層７を、接着剤層６を面して転写した層である。
紫外線遮光層７は、紫外線を遮断可能であり、且つ、容易に破断する事が可能な層であれば特に限定されない。例えば、金属材料からなる薄膜（金属薄膜）である。
金属材料は特に限定されないが、薄膜が形成し易く、高価な材料では無い材料であれば好適に使用可能である。例えば、アルミニウム薄膜を挙げる事ができる。
厚さとしては、紫外線を遮断可能な厚さであれば良い。例えば、数ｎｍ～数μｍの薄膜であれば、十分な紫外線遮光性を備えており、且つ容易に破断する事ができるため、好適である。(transfer layer)
The transfer layer 14 is a layer in which the ultraviolet light shielding layer 7 is formed on the adhesive layer 6. This is a layer in which the adhesive layer 6 and the ultraviolet light shielding layer 7 are transferred from above the joint portion 9 of the power supply mechanism 10, with the adhesive layer 6 facing, using a transfer layer transfer film 13, which will be described later.
The ultraviolet light shielding layer 7 is not particularly limited as long as it is a layer that can block ultraviolet light and can be easily broken. For example, it is a thin film made of a metal material (metal thin film).
The metal material is not particularly limited, but any material that can be easily formed into a thin film and is not an expensive material can be suitably used. For example, an aluminum thin film can be mentioned.
The thickness may be any thickness that can block ultraviolet rays. For example, a thin film of several nanometers to several micrometers is suitable because it has sufficient ultraviolet light shielding properties and can be easily broken.
（接着剤層）
接着剤層６は、紫外線遮光層７と透明導電層２の間に挿入され、それらを接着すると同時に、両者の導通をとるものである。
接着剤層６の材料としては、エチレン・酢酸ビニル共重合体、エチレンエチルアクリレート共重合体、ポリアミド樹脂、塩化ビニル・酢酸ビニル共重合体、スチレン系樹脂、アクリル系樹脂、ポリウレタン系樹脂、エポキシ樹脂から選択した単体、または混合体からなる組成物とする事が好ましい。
接着剤層６の厚さとしては５０μｍ以下である事が好ましい。５０μｍを超えると、熱が伝わり難くなる事による、熱硬化が不十分になる虞がある。また、その為に美装性が損なわれる虞もある。(Adhesive layer)
The adhesive layer 6 is inserted between the ultraviolet light shielding layer 7 and the transparent conductive layer 2, and serves to adhere them and at the same time establish electrical continuity between them.
Materials for the adhesive layer 6 include ethylene/vinyl acetate copolymer, ethylene ethyl acrylate copolymer, polyamide resin, vinyl chloride/vinyl acetate copolymer, styrene resin, acrylic resin, polyurethane resin, and epoxy resin. It is preferable to use a composition consisting of a single substance or a mixture selected from the following.
The thickness of the adhesive layer 6 is preferably 50 μm or less. If it exceeds 50 μm, there is a risk that heat curing will be insufficient due to difficulty in transmitting heat. Moreover, there is also a possibility that the aesthetic appearance may be impaired.
（紫外線遮光層）
紫外線遮光層７としては、十分な紫外線遮光性を備えていれば、材料や厚さに関して特に限定する必要は無い。
紫外線遮光層７の材料としては、遮光性が高い為、各種の金属材料を好適に使用する事ができる。下地との密着性の良さ、環境上の問題、材料価格、薄膜形成の容易さ、などを考慮すると、従来から樹脂フィルム上に形成されて来たアルミニウムを好適に使用する事ができる。
紫外線遮光層７の膜厚としては、数ｎｍ～１０００μｍの薄膜であれば、十分な紫外線遮光性を備えており、且つ容易に破断する事ができるため、好適に使用する事ができる。破断をより容易に実行可能とする為、１０μｍ以下である事がより好ましい。厚さが１０００μｍを超えると調光体の本体との段差が目立つ為、美装性を損なう虞がある。(Ultraviolet light shielding layer)
The material and thickness of the ultraviolet light shielding layer 7 do not need to be particularly limited as long as they have sufficient ultraviolet light shielding properties.
As the material for the ultraviolet light shielding layer 7, various metal materials can be suitably used because of their high light shielding properties. Considering good adhesion to the base, environmental issues, material cost, ease of forming a thin film, etc., aluminum, which has been conventionally formed on a resin film, can be suitably used.
As for the thickness of the ultraviolet light shielding layer 7, a thin film of several nm to 1000 μm can be suitably used because it has sufficient ultraviolet light shielding properties and can be easily broken. It is more preferable that the diameter is 10 μm or less in order to make it easier to break. If the thickness exceeds 1000 μm, the level difference between the light control body and the main body will be noticeable, which may impair the aesthetic appearance.
＜調光体＞
調光体２０の本体は、透明基材１の表面に透明導電層２が形成された一対の基板８の透明導電層２側を内側にして、調光層３を挟持したものである。調光層３は、電圧を印加する事によって、透明な状態から不透明になったり、逆に不透明な状態から透明になる材料からなる層である。材料としては、高分子分散型液晶（ＰＤＬＣ）やポリマーネットワーク型液晶（ＰＮＬＣ）などを好適に用いる事ができるが、これらに限定する必要は無く、上記の機能を有する材料であれば使用することができる。<Dimmer>
The main body of the light control body 20 is made up of a pair of substrates 8 each having a transparent conductive layer 2 formed on the surface of a transparent base material 1, with the transparent conductive layer 2 side facing inside and the light control layer 3 sandwiched therebetween. The light control layer 3 is a layer made of a material that changes from a transparent state to an opaque state, or vice versa, from an opaque state to a transparent state by applying a voltage. As the material, polymer dispersed liquid crystal (PDLC), polymer network liquid crystal (PNLC), etc. can be suitably used, but there is no need to limit it to these, and any material having the above-mentioned functions can be used. I can do it.
調光体２０としては、上記の調光体２０の本体と、その本体の一対の基板８の透明導電層２の端部に給電部材５を接続する給電機構１０を備えている。 The light control body 20 includes a main body of the light control body 20 described above, and a power supply mechanism 10 that connects a power supply member 5 to the ends of the transparent conductive layer 2 of a pair of substrates 8 of the main body.
＜転写層転写フィルム＞
次に、図２を用いて、本発明の転写層転写フィルム１３を説明する。
本発明の転写層転写フィルム１３は、基材フィルム１１の上に、剥離層１２と、紫外線遮光層７と、接着剤層６と、をこの順に備えている事が特徴である。<Transfer layer transfer film>
Next, the transfer layer transfer film 13 of the present invention will be explained using FIG. 2.
The transfer layer transfer film 13 of the present invention is characterized in that it includes a release layer 12, an ultraviolet light shielding layer 7, and an adhesive layer 6 on the base film 11 in this order.
（基材フィルム）
基材フィルム１１は、耐熱性を有するプラスチックフィルムであれば特に限定はされない。剥離性の観点からは二軸延伸ポリプロピレンフィルム、耐熱性の観点からは二軸延伸ポリエステルフィルムが好適である。
基材フィルム１１の厚さは、８μｍ～２５０μｍが好ましい。８μｍ未満であるとハンドリングが困難となり、製造工程で生じる各種の損傷により品質の維持が難しくなる虞がある。２５０μｍより厚くなると、熱圧着時の導熱が不十分となり、熱圧着不良を招く虞がある。(Base film)
The base film 11 is not particularly limited as long as it is a heat-resistant plastic film. From the viewpoint of releasability, a biaxially oriented polypropylene film is preferred, and from the viewpoint of heat resistance, a biaxially oriented polyester film is preferred.
The thickness of the base film 11 is preferably 8 μm to 250 μm. If it is less than 8 μm, it will be difficult to handle, and there is a risk that it will be difficult to maintain quality due to various damages that occur during the manufacturing process. When the thickness exceeds 250 μm, heat conduction during thermocompression bonding becomes insufficient, which may lead to poor thermocompression bonding.
（剥離層）
剥離層１２は、転写層転写フィルム１３を調光体２０の接合部９の上から熱転写する際に、紫外線遮光層７と接着剤層６の積層体が容易に剥離して転写可能とするものである。
ただし、基材フィルム１１と紫外線遮光層７とが、容易に剥離できる場合は、積極的に剥離層１２を設ける必要は無い。(Peeling layer)
The peeling layer 12 allows the laminate of the ultraviolet light shielding layer 7 and the adhesive layer 6 to be easily peeled off and transferred when the transfer layer transfer film 13 is thermally transferred from above the joint portion 9 of the light control body 20. It is.
However, if the base film 11 and the ultraviolet light shielding layer 7 can be easily separated, there is no need to actively provide the release layer 12.
次に、本発明の実施例を用いて更に詳しく説明する。 Next, the present invention will be explained in more detail using examples.
＜実施例１＞
（転写層転写フィルムの作製）
まず、基材フィルムとして、厚さ２５μｍのポリエステルフィルム（ルミラーＦ６５、東レ製）を用い、その一方の面に剥離層として剥離ニス４５－３（昭和インク製）を、バーコーターを用いて乾燥後の厚さが０．５～２．０μｍに入る様に調整し、塗布、乾燥し、剥離層を形成した。<Example 1>
(Preparation of transfer layer transfer film)
First, a 25 μm thick polyester film (Lumirror F65, manufactured by Toray Industries) was used as the base film, and release varnish 45-3 (manufactured by Showa Ink) was applied as a release layer on one side of the film, and after drying using a bar coater. The film was coated and dried to form a release layer.
次に、剥離層の上に紫外線遮光層として、真空蒸着法を用いて厚さ５０ｎｍのアルミニウム薄膜を形成した。 Next, a 50 nm thick aluminum thin film was formed as an ultraviolet light shielding layer on the release layer using a vacuum evaporation method.
次に、アルミニウム薄膜の上に、接着剤層として、変性アクリルコートＳＥ－７０ ホワイト（和信化学工業製）に酢酸ビニル塩化ビニル共重合体を加えた接着材料を使用し、バーコーターを用いて、厚さ０．５μｍ～１．０μｍに入る様に調整して、塗布、乾燥を行う事により接着剤層を形成した。
この様にして、転写層転写フィルムを得た後、１５ｍｍ×１５ｍｍの大きさに切り出して、熱転写に使用する転写層転写フィルムとした。Next, on the aluminum thin film, an adhesive material made of modified acrylic coat SE-70 White (manufactured by Wasshin Chemical Industry Co., Ltd.) to which vinyl acetate vinyl chloride copolymer was added was used as an adhesive layer, and a bar coater was used to coat the adhesive layer. An adhesive layer was formed by coating and drying the adhesive layer, adjusting the thickness to be between 0.5 μm and 1.0 μm.
After obtaining a transfer layer transfer film in this manner, it was cut into a size of 15 mm x 15 mm to obtain a transfer layer transfer film used for thermal transfer.
（調光体の本体の作製）
基材として、ポリエチレンテレフタレート（ＰＥＴ）フィルムの一方の面にＩＴＯを成膜した透明導電層付きＰＥＴフィルム（以後、ＩＴＯ－ＰＥＴと記す。）を２枚用いて、双方の透明導電層を向い合せにして、液晶材料（ＰＮＬＣ）からなる調光層を挟持して、厚さ２０μｍの調光層を備えた調光体の本体を得た。この液晶材料は、平均粒子径８０ｎｍ～１５０ｎｍのＰＮＬＣ液晶が高分子膜に包まれたカプセルを有するものである。なお、ここで平均粒子径は、レーザー回折／散乱法による体積基準の平均粒子径である。(Preparation of main body of light control body)
As a base material, two PET films with transparent conductive layers (hereinafter referred to as ITO-PET) in which ITO is deposited on one side of a polyethylene terephthalate (PET) film are used, and both transparent conductive layers are placed facing each other. A light control layer made of a liquid crystal material (PNLC) was sandwiched therebetween to obtain a main body of a light control body having a light control layer having a thickness of 20 μm. This liquid crystal material has a capsule in which a PNLC liquid crystal having an average particle diameter of 80 nm to 150 nm is wrapped in a polymer film. Note that the average particle diameter here is a volume-based average particle diameter determined by a laser diffraction/scattering method.
（ＩＴＯ層の取り出し）
まず、作製した調光体の本体を断裁してＡ４サイズの調光体を作製した。断裁した調光体の２つの短辺を上下とした場合、ＩＴＯ－ＰＥＴの短辺側のうち左下角部から短辺方向に１０ｍｍ、長辺方向に７ｍｍ、まで薄手の金属板を用いて剥離し、そのＩＴＯ－ＰＥＴを切除することにより、調光層を露出させた。(Removal of ITO layer)
First, the main body of the produced light control body was cut to produce an A4 size light control body. When the two short sides of the cut light control body are the top and bottom, peel off using a thin metal plate from the lower left corner of the short side of the ITO-PET to 10 mm in the short side direction and 7 mm in the long side direction. Then, the ITO-PET was cut away to expose the light control layer.
次に、それぞれ露出した調光層を、調光層を拭き取り可能な溶剤を浸みこませた不織布を用いて拭き取る事で、ＩＴＯ層を露出させた。 Next, the ITO layer was exposed by wiping off each exposed light control layer using a nonwoven cloth impregnated with a solvent capable of wiping off the light control layer.
次に、調光体を裏返しにして、同様にして調光層を露出させ、調光層を拭き取り可能な溶剤を浸みこませた不織布を用いて拭き取る事で、ＩＴＯ層を露出させた。
以上により、２枚のＩＴＯ－ＰＥＴのＩＴＯ層が露出され、調光層への通電が可能となった。Next, the light control body was turned over, the light control layer was exposed in the same manner, and the ITO layer was exposed by wiping the light control layer with a nonwoven cloth impregnated with a wipeable solvent.
As a result of the above, the ITO layers of the two ITO-PET sheets were exposed, and it became possible to conduct electricity to the light control layer.
（給電機構の付与）
２枚のＩＴＯ－ＰＥＴのＩＴＯ層が露出された調光体に対して、次のようにして給電機構を設置した。(Provision of power supply mechanism)
A power supply mechanism was installed in the following manner on a light control body in which the ITO layers of two ITO-PET sheets were exposed.
まず、調光体の露出したＩＴＯ層の上に、導電性接着剤として、異方性導電フィルム ＣＰ９２３ＣＭ－２５ＡＣ（デクセリアルズ社製）を積層した。 First, an anisotropic conductive film CP923CM-25AC (manufactured by Dexerials) was laminated as a conductive adhesive on the exposed ITO layer of the light control body.
次に、その異方性導電フィルムの上に、給電部材として、ポリイミドフィルムの上に銅箔を接着した標準ＦＰＣ（厚さ２５μｍのポリイミドフィルム上に厚さ１８μｍの銅箔を片面に備えたＦＰＣ、沖電気製）に配線パターンを形成したものを使用して、その銅箔側を異方性導電フィルム側にして積層し、接合部を形成した。 Next, on top of the anisotropic conductive film, a standard FPC with a copper foil bonded on a polyimide film (an FPC with a 18 μm thick copper foil on one side on a 25 μm thick polyimide film) was used as a power supply member. (manufactured by Oki Electric) with a wiring pattern formed thereon, and were laminated with the copper foil side facing the anisotropic conductive film side to form a joint.
次に、接合部の上およびＩＴＯ層を被覆する様に、１５ｍｍ×１５ｍｍに切り出した転写層転写フィルムの接着剤層側を面して積層した。 Next, the transfer layer transfer film cut into a size of 15 mm x 15 mm was laminated with the adhesive layer side facing so as to cover the joint portion and the ITO layer.
次に、転写層転写フィルムの裏面（紫外線遮光層側）から１０ｍｍ×７ｍｍの寸法を有するサーマルヘッドを備えた熱転写装置を用いて１８０℃、０．５ＭＰａの熱圧条件にて、紫外線遮光層と接着剤層からなる転写層を、熱転写した。
同じ作業を、もう１つの露出したＩＴＯ層にも実施した。Next, the ultraviolet light shielding layer was transferred from the back side of the transfer layer transfer film (the side of the ultraviolet light shielding layer) using a thermal transfer device equipped with a thermal head having dimensions of 10 mm x 7 mm under heat and pressure conditions of 180°C and 0.5 MPa. A transfer layer consisting of an adhesive layer was thermally transferred.
The same operation was performed on the other exposed ITO layer.
その結果、転写層転写フィルムのサーマルヘッドで熱圧したエリアのみに、転写層が転写し、アルミニウム蒸着膜で被覆された給電機構が、調光体に設置され、給電可能な調光体が得られた。 As a result, the transfer layer was transferred only to the area heated and pressed by the thermal head of the transfer layer transfer film, and a power supply mechanism covered with an aluminum vapor-deposited film was installed on the light control body, resulting in a light control body capable of supplying power. It was done.
＜実施例２＞
異方性導電フィルムとして、導電性接着剤テープ♯９７０７を用いた以外は、実施例１と同様にして、給電可能な調光体を作製した。<Example 2>
A light control body capable of supplying power was produced in the same manner as in Example 1, except that conductive adhesive tape #9707 was used as the anisotropic conductive film.
＜比較例１＞
紫外線遮光層と接着剤層からなる転写層を熱転写しなかった事を除き、実施例１と同様にして、給電可能な調光体を作製した。<Comparative example 1>
A light control body capable of supplying power was produced in the same manner as in Example 1, except that the transfer layer consisting of the ultraviolet light shielding layer and the adhesive layer was not thermally transferred.
＜比較例２＞
接着剤層のみからなる転写層を熱転写した事を除き、実施例１と同様にして、給電可能な調光体を作製した。<Comparative example 2>
A light control body capable of supplying power was produced in the same manner as in Example 1, except that the transfer layer consisting only of the adhesive layer was thermally transferred.
＜比較例３＞
転写層転写フィルムを使用せずに、アルミ基材粘着テープ ♯８３０３（寺岡製作所製）を１５ｍｍ×１２ｍｍに切り出して、接合部およびＩＴＯ層を被覆する様に、手作業にて貼合した事以外は、実施例１と同様とした。<Comparative example 3>
Except for cutting out aluminum-based adhesive tape #8303 (manufactured by Teraoka Seisakusho) into 15 mm x 12 mm pieces and pasting them together by hand to cover the joint and ITO layer without using a transfer layer transfer film. was the same as in Example 1.
＜比較例４＞
サーマルヘッドを備えた熱転写装置を用いて、２９０℃、０．５ＭＰａの熱圧条件にて、紫外線遮光層と接着剤層からなる転写層を、熱転写した事以外は実施例１と同様とした。２９０℃はＰＥＴフィルムの融点２７０℃を超える温度である。その為、基材であるＰＥＴフィルムが溶融分解し、調光体として機能しなかった。<Comparative example 4>
The procedure was the same as in Example 1 except that the transfer layer consisting of the ultraviolet light shielding layer and the adhesive layer was thermally transferred using a thermal transfer device equipped with a thermal head under heat and pressure conditions of 290° C. and 0.5 MPa. 290°C is a temperature exceeding the melting point of PET film, 270°C. Therefore, the PET film that was the base material melted and decomposed and did not function as a light control body.
＜比較例５＞
サーマルヘッドを備えた熱転写装置を用いて、５０℃、０．５ＭＰａの熱圧条件にて、紫外線遮光層と接着剤層からなる転写層を、熱転写した事以外は実施例１と同様とした。その結果、転写層の接着剤層と導電性接着剤層が、加熱不足で熱硬化せず、給電機構を設置する事ができなかった為、調光体として機能しなかった。<Comparative example 5>
Example 1 was carried out in the same manner as in Example 1, except that the transfer layer consisting of the ultraviolet light shielding layer and the adhesive layer was thermally transferred using a thermal transfer device equipped with a thermal head under heat and pressure conditions of 50° C. and 0.5 MPa. As a result, the adhesive layer and the conductive adhesive layer of the transfer layer were not thermally cured due to insufficient heating, and a power supply mechanism could not be installed, so that the adhesive layer did not function as a light control body.
＜調光体の特性評価＞
実施例１～２および比較例１～３で得られた調光体（比較例４と５は除外）を、透明粘着フィルムＯＣＡ８１４６（スリーエム社製）を用い、厚さ３ｍｍで、２５０ｍｍ×３５
０ｍｍのガラス板に貼り付けた。調光体において、電極以外の外周端部にはアルミ基材粘着テープを貼り付け、水分その他の影響を排除した。また、給電部となるＦＰＣの端部、金属がむき出しとなった部分にもアルミ基材粘着テープを貼り付けた。<Characteristics evaluation of light control body>
The light control bodies obtained in Examples 1 to 2 and Comparative Examples 1 to 3 (Comparative Examples 4 and 5 were excluded) were prepared using a transparent adhesive film OCA8146 (manufactured by 3M Co., Ltd.) with a thickness of 3 mm and a size of 250 mm x 35 mm.
It was attached to a 0 mm glass plate. In the light control body, aluminum-based adhesive tape was pasted on the outer peripheral edge of the body other than the electrodes to eliminate the influence of moisture and other factors. In addition, aluminum-based adhesive tape was attached to the end of the FPC that would serve as the power feeding section, where the metal was exposed.
（初期特性の評価）
ガラス板に貼合した調光体のＡサイズの中心部について光学特性（ヘイズ）の測定を行った。測定には、ヘイズメーター ＮＤＨ－７０００（スガ試験機社製）を用いた。調光体の動作確認のために、無通電の状態でヘイズを測定し、更にＡＣ４０Ｖ（５０Ｈｚ）を印加した後、ヘイズを測定した。(Evaluation of initial characteristics)
The optical properties (haze) of the A-sized center of the light control body bonded to the glass plate were measured. For the measurement, a haze meter NDH-7000 (manufactured by Suga Test Instruments Co., Ltd.) was used. To confirm the operation of the light control body, the haze was measured in a non-energized state, and after applying AC40V (50Hz), the haze was measured.
（信頼性の評価）
ガラス板に貼合した調光体を、ガラス面が上になる様にしてＳＵＳ製のフレームにはめ込み、３か月間屋外に放置した後、ＳＵＳ製フレームから取り外し、初期特性の評価と同様にして光学特性を測定した。(Reliability evaluation)
The light control body bonded to the glass plate was fitted into a SUS frame with the glass side facing up, and after being left outdoors for 3 months, it was removed from the SUS frame and evaluated in the same manner as the initial characteristic evaluation. Optical properties were measured.
測定結果を、まとめて表１に示す。 The measurement results are summarized in Table 1.
表１に示す様に、実施例１、２は３か月の屋外放置した後も、給電機構の劣化は見られず、初期と同様に機能した。
一方、比較例１、２は、調光体に通電しても機能しなかった。解析の結果、接合部の導通不良が発生していた。
これは、屋外環境の紫外線および水分により電極部材が劣化した為と推定される。
比較例３では、アルミ基材粘着テープを適切な位置に貼合する事ができず、調光体の美装性を損なう結果となった。
比較例５は、給電機構が脱落したため、給電を行う事ができず、調光体として機能しなかった。As shown in Table 1, in Examples 1 and 2, even after being left outdoors for three months, no deterioration of the power feeding mechanism was observed, and the devices functioned in the same manner as in the initial stage.
On the other hand, Comparative Examples 1 and 2 did not function even when the light control body was energized. As a result of the analysis, a conduction failure occurred at the joint.
This is presumed to be because the electrode members were deteriorated by ultraviolet rays and moisture in the outdoor environment.
In Comparative Example 3, the aluminum-based adhesive tape could not be bonded to an appropriate position, resulting in a loss of aesthetics of the light control body.
In Comparative Example 5, the power supply mechanism fell off, so power could not be supplied and the device did not function as a light control body.
