Description
Translated fromChinese技术领域technical field
本发明涉及一种景变防伪结构和防伪塑封及制备方法，属于防伪技术领域。The invention relates to a landscape change anti-counterfeiting structure, an anti-counterfeiting plastic seal and a preparation method, and belongs to the technical field of anti-counterfeiting.
背景技术Background technique
酒瓶、饮料瓶、化妆品瓶、调味瓶等包装瓶，尤其是一些名贵白酒、红酒的酒瓶，在瓶口的上面会套有塑封筒状的防伪塑封，紧紧的包裹在瓶盖上，用于瓶盖的密封和防伪。这种防伪塑封通常包括帽体和帽顶，制作工艺为首先在长条状的热收缩型薄膜的外表面上印刷防伪涂层，接着通过防伪塑封成型工艺卷绕成筒状帽体，接缝处通常采用粘结剂粘结固定，最后将裁剪好的圆形帽顶在接缝处使用粘结剂粘结在帽体的上面，形成一个具有封顶的防伪塑封。Packaging bottles such as wine bottles, beverage bottles, cosmetic bottles, seasoning bottles, etc., especially for some precious white wine and red wine bottles, will be covered with a plastic-sealed cylindrical anti-counterfeiting plastic seal, which is tightly wrapped on the bottle cap. For sealing and anti-counterfeiting of bottle caps. This anti-counterfeiting plastic seal usually includes a cap body and a cap top. The production process is to first print an anti-counterfeiting coating on the outer surface of a long heat-shrinkable film, and then roll it into a cylindrical cap body through the anti-counterfeiting plastic sealing molding process. Adhesive is usually used to fix the cap, and finally the cut round cap top is bonded to the top of the cap body at the seam with an adhesive to form an anti-counterfeiting plastic seal with a cap.
上述防伪塑封在实际使用过程中存在以下问题：1）现有防伪涂层通常采用荧光防伪、温变防伪、激光防伪等制备工艺，制备工艺为丝网印刷、胶印、凹印或涂布工艺，采用普通的印刷与涂布设备均可完成，存在技术难度不高，很容易被仿制的问题；2）防伪涂层位于热收缩型薄膜的外面，很容易被刮花甚至脱落，严重影响防伪和外观效果；也因为防伪功能层印刷在瓶帽外层，导致大部分防伪功能层容易受到酒精等腐蚀性液体的腐蚀，从而导致防伪功能失效；3）印有防伪涂层的一面由于油墨的存在，导致在帽身的接缝处以及帽身与帽顶的接缝处仅使用粘结剂无法粘结牢固，不法分子可以使用刀片沿着接缝处划开粘结剂或沿着接缝处用力撕开，就可以完整的回收防伪塑封的帽体和帽顶，套用在假冒商品上，再次用粘结剂粘结帽体的接缝处以及帽体与帽顶的接缝处，重复使用，从而让普通消费者和市场监督人员无法识别商品的真伪，给企业造成了巨大的经济损失和信誉损失，同时也严重侵害了消费者的利益。The above-mentioned anti-counterfeiting plastic seal has the following problems in the actual use process: 1) The existing anti-counterfeiting coating usually adopts the preparation process of fluorescence anti-counterfeiting, temperature-varying anti-counterfeiting, laser anti-counterfeiting, etc. The preparation process is screen printing, offset printing, gravure printing or coating process, It can be completed by ordinary printing and coating equipment, but there are problems that the technical difficulty is not high and it is easy to be imitated; 2) The anti-counterfeiting coating is located on the outside of the heat-shrinkable film, which is easy to be scratched or even peeled off, which seriously affects the anti-counterfeiting and Appearance effect; also because the anti-counterfeiting functional layer is printed on the outer layer of the bottle cap, most of the anti-counterfeiting functional layer is easily corroded by corrosive liquids such as alcohol, resulting in the failure of the anti-counterfeiting function; 3) The side printed with the anti-counterfeiting coating is due to the presence of ink , resulting in the joint of the cap body and the joint between the cap body and the top of the cap cannot be firmly bonded with only the adhesive. The criminals can use a blade to cut the adhesive along the seam or along the seam. By tearing it apart, you can completely recycle the anti-counterfeiting plastic-encapsulated cap body and cap top, apply it to counterfeit goods, and use adhesive to bond the joint of the cap body and the joint between the cap body and the cap top, and reuse it. , so that ordinary consumers and market supervisors cannot identify the authenticity of goods, causing huge economic losses and reputation losses to enterprises, and also seriously infringing on the interests of consumers.
针对第三个问题，现有技术的解决方案中有采用高温熔融技术通过熔融装置对已经通过粘结剂粘结的防伪塑封的接缝处进行高温处理，使得接缝处的材料充分熔合，形成熔合印记，结合的更牢固，但是引进熔融设备的成本非常高，增加了产品生产成本增高，熔融装置在接缝处形成的融合印记，使结合印处产生变形、凸起式波纹印迹，较大的影响了产品的整体的美观度，而且增加了防伪塑封成型工艺的工序，工艺变得更加复杂。For the third problem, the solution in the prior art is to use high-temperature melting technology to perform high-temperature treatment on the seam of the anti-counterfeiting plastic seal that has been bonded by the adhesive through a melting device, so that the materials at the seam are fully fused to form The fusion mark is more firmly combined, but the cost of introducing melting equipment is very high, which increases the production cost of the product. It affects the overall aesthetics of the product, and increases the process of the anti-counterfeiting plastic molding process, and the process becomes more complicated.

本发明的有益技术效果：Beneficial technical effects of the present invention:
本发明的一种景变防伪结构，通过第一和第二磁性油墨涂层的叠加以及第一磁性颜料片和第二磁性颜料片的尺寸和位置关系设置，实现景变防伪效果，即图案变化的同时颜色也变化。这种变化可以通过防伪结构和观察者角度不变，改变光照角度来实现。第一磁性颜料片与基层夹角为10～60°，第二磁性颜料片与第一磁性颜料片的夹角为85～95°之间的任一角度，或者说第二磁性颜料片与基层的夹角为-25～-85°，所谓负度数是指第二角度与第一角度相反。第一和第二磁性颜料片的厚度为0.5-3μm，直径为10-30μm，第一和第二磁性颜料片排列间隔分别为大于等于对应的颜料片直径×对应的与基层夹角的余弦的绝对值，优选的第一磁性颜料片排列间隔增加1～3μm，第二磁性颜料片排列间隔增加了6～14μm。在基层的表面形成了两层磁性油墨重叠区（第一颜料片遮挡第二颜料片）、单独第一磁性油墨涂层区和单独第二磁性油墨涂层区。A scene change anti-counterfeiting structure of the present invention realizes the scene change anti-counterfeiting effect through the superposition of the first and second magnetic ink coatings and the setting of the size and positional relationship of the first magnetic pigment flakes and the second magnetic pigment flakes, that is, pattern change. at the same time the color changes. This change can be achieved by changing the illumination angle with the anti-counterfeiting structure and the observer's angle unchanged. The included angle between the first magnetic pigment flake and the base layer is 10-60°, the included angle between the second magnetic pigment flake and the first magnetic pigment flake is any angle between 85-95°, or the second magnetic pigment flake and the base layer The included angle is -25 to -85°. The so-called negative degree means that the second angle is opposite to the first angle. The thickness of the first and second magnetic pigment flakes is 0.5-3 μm, the diameter is 10-30 μm, and the arrangement interval of the first and second magnetic pigment flakes is greater than or equal to the diameter of the corresponding pigment flake × the cosine of the corresponding angle with the base layer. In absolute value, the preferred arrangement interval of the first magnetic pigment flakes is increased by 1-3 μm, and the arrangement interval of the second magnetic pigment flakes is increased by 6-14 μm. Two layers of magnetic ink overlapping areas (the first pigment flakes shield the second pigment flakes), a separate first magnetic ink coating area and a separate second magnetic ink coating area are formed on the surface of the base layer.
如图1-3所示，对于颜料片与基层及颜料片之间的相对位置已确定的景变防伪结构，具有如下景变防伪效果。As shown in Figure 1-3, the landscape change anti-counterfeiting structure with the determined relative positions between the pigment flakes, the base layer and the pigment flakes has the following landscape change anti-counterfeiting effects.
当光线从上方照射到景变防伪结构时，对于两层磁性油墨重叠区，由于光线照射到第一磁性颜料片上被反射后射向人眼，第二磁性油墨涂层的图案被遮挡，仅清晰显示所述第一磁性油墨涂层的图案；同样对于单独第一磁性油墨涂层区仅清晰显示所述第一磁性油墨涂层的图案；对于单独第二磁性油墨涂层，由于光照角度以及所述第二磁性颜料片尺寸、角度和间隔设置（优选的增加了6-14μm），使得大部分光线从所述第二磁性颜料片的间隙透过，且能观察到的颜料片的宽度（约为第二磁性颜料片直径×cos（25～85°））为20微米以下，远小于第一颜料片可观察到的宽度（约为第一磁性颜料片直径×cos（10～60°）μm），由于百叶窗原理，在每片叶片足够小且观察距离足够远的情况下，肉眼无法看到第二磁性油墨涂层的图案。因此当光线从上方照射到景变防伪结构时，仅清晰显示所述第一磁性油墨涂层的图案。When light irradiates the scene change anti-counterfeiting structure from above, for the overlapping area of the two layers of magnetic ink, the pattern of the second magnetic ink coating is blocked because the light irradiates on the first magnetic pigment sheet and is reflected and then directed to the human eye, and only clear The pattern of the first magnetic ink coating is displayed; also for the first magnetic ink coating area alone, only the pattern of the first magnetic ink coating is clearly displayed; for the second magnetic ink coating alone, due to the illumination angle and all The size, angle and spacing of the second magnetic pigment flakes are set (preferably increased by 6-14 μm), so that most of the light passes through the gaps of the second magnetic pigment flakes, and the width of the pigment flakes that can be observed (about The diameter of the second magnetic pigment flake × cos (25-85°)) is less than 20 microns, which is much smaller than the observable width of the first pigment flake (about the diameter of the first magnetic pigment flake × cos (10-60°) μm ), due to the shutter principle, the pattern of the second magnetic ink coating cannot be seen by the naked eye when each blade is small enough and the viewing distance is far enough. Therefore, only the pattern of the first magnetic ink coating is clearly displayed when the light irradiates the scene change anti-counterfeiting structure from above.
当光线垂直基材照射到景变防伪结构上时，对于两层磁性油墨重叠区以及单独第二磁性油墨涂层，所述第一磁性颜料片和第二磁性颜料片的表面的反射光光均射向人眼，因此可能同时显示两层的图案；为了改善图案效果，优选的，在原有间隔的基础上，第二磁性颜料片的间隔增加6～14μm，增加颜料片的透光性，使得大部分光线从所述第二磁性颜料片的间隙透过，以弱化其视觉效果，使得对于两层磁性油墨重叠区以及单独第一和第二磁性油墨涂层，无法看到第二磁性油墨层图案，仍可清晰看到第一磁性油墨涂层的图案。When the light perpendicular to the substrate is irradiated on the anti-counterfeiting structure, for the overlapping area of the two layers of magnetic ink and the second magnetic ink coating alone, the reflected light on the surfaces of the first magnetic pigment flakes and the second magnetic pigment flakes is uniform. To the human eye, it is possible to display two-layer patterns at the same time; in order to improve the pattern effect, preferably, on the basis of the original interval, the interval between the second magnetic pigment flakes is increased by 6-14 μm to increase the light transmittance of the pigment flakes, so that the Most of the light is transmitted through the gaps of the second magnetic pigment flakes to weaken its visual effect, so that the second magnetic ink layer cannot be seen for the overlapping area of the two layers of magnetic ink and the first and second magnetic ink coatings alone pattern, the pattern of the first magnetic ink coating can still be clearly seen.
改变光线照射角度直到光线从下方的低略角度照射到景变防伪结构时，由于光线照射角度以及所述第一磁性颜料片尺寸、角度和间隔设置（优选的增加1-3μm），大部分光线从所述第一磁性颜料片的间隙透过，肉眼无法看到第一磁性油墨涂层的图案，对于两层磁性油墨重叠区、和单独第一和第二磁性油墨涂层，无法显示第一磁性油墨层图案，仅清晰显示所述第二磁性油墨涂层的图案。When the light irradiation angle is changed until the light irradiates the scene change anti-counterfeiting structure from a low angle below, due to the light irradiation angle and the size, angle and spacing of the first magnetic pigment flakes (preferably increased by 1-3 μm), most of the light Through the gaps of the first magnetic pigment flakes, the pattern of the first magnetic ink coating cannot be seen by the naked eye. For the overlapping area of the two layers of magnetic ink, and the first and second magnetic ink coatings alone, the first magnetic ink coating cannot be displayed. The pattern of the magnetic ink layer, only the pattern of the second magnetic ink coating is clearly displayed.
当然这种景变效果也可以通过保持观察者角度和光照角度不变，而改变防伪结构的角度来实现。例如上下移动防伪结构、垂直转动防伪结构0-90°，或者转动180°以使上下颠倒位置，或者保持光照和防伪结构位置不变，视线相对基层外表面从0°到180°移动，都可以实现空中变脸效果，在第一磁性油墨层图案和第二磁性油墨层图案之间转变，且尽量减少图案重叠，重叠范围为10°左右。优选的，第一磁性颜料片与基层夹角为10-30°且与第二磁性颜料片的夹角为90°，以减少图案重叠，使得任一种图案更加清晰。Of course, this kind of scene change effect can also be achieved by changing the angle of the anti-counterfeiting structure while keeping the observer's angle and the illumination angle unchanged. For example, moving the anti-counterfeiting structure up and down, rotating the anti-counterfeiting structure vertically 0-90°, or rotating 180° to make the position upside down, or keeping the position of the light and the anti-counterfeiting structure unchanged, and moving the line of sight relative to the outer surface of the base layer from 0° to 180°, all can To achieve the effect of changing face in the air, the pattern of the first magnetic ink layer and the pattern of the second magnetic ink layer are changed, and the overlapping of the patterns is minimized, and the overlapping range is about 10°. Preferably, the angle between the first magnetic pigment flake and the base layer is 10-30° and the angle between the first magnetic pigment flake and the second magnetic pigment flake is 90°, so as to reduce pattern overlap and make any pattern clearer.
优选的，不同油墨层的磁性针状颜料具有不同金属光泽颜色，例如银色和金色，从而实现在同一位置图案变化的同时伴随颜色的变化，防伪效果更好。Preferably, the magnetic needle-shaped pigments of different ink layers have different metallic luster colors, such as silver and gold, so that the pattern changes at the same position and the color changes are accompanied, and the anti-counterfeiting effect is better.
本发明的一种用于瓶口的防伪塑封，帽体和/或帽顶的内表面非满版印刷上述一种景变防伪结构一种景变防伪结构，一方面，使磁性油墨层受到基层的保护，从外面无法直接接触到防伪结构，不会出现防伪功能层被刮花甚至脱落的问题；另一方面，在帽顶的外边缘和帽体的一端留出非印刷区，保证在帽体接缝处和帽顶接缝处用于粘结的表面都是光滑的基层薄膜，便于粘结，从而仅通过粘结剂即可实现接缝处的牢固连接，恶意的用力撕或刮接缝处就会撕裂或刮坏塑封，使得该防伪塑封无法回收再利用，极大的提高了防伪塑封的安全、可靠的防伪性能，无法用于假冒伪劣，更重要的是使得只使用普通的热烫印工艺就能合成粘结牢固的该防伪塑封，无需使用热熔合设备，极大的降低了成本，而且简化了成型工序。In the anti-counterfeiting plastic seal for bottle mouth of the present invention, the inner surface of the cap body and/or the top of the cap is not fully printed with the above-mentioned landscape change anti-counterfeiting structure. The anti-counterfeiting structure cannot be directly contacted from the outside, and the problem of scratching or even falling off the anti-counterfeiting functional layer will not occur; The surfaces used for bonding at the body seam and the top seam are smooth base film for easy bonding, so that a strong connection at the seam can be achieved with only the adhesive, malicious tearing or scraping The seam will tear or scratch the plastic seal, making the anti-counterfeiting plastic seal unable to be recycled and reused, which greatly improves the security and reliable anti-counterfeiting performance of the anti-counterfeiting plastic seal. The hot stamping process can synthesize the firmly bonded anti-counterfeiting plastic seal, without the use of thermal fusion equipment, which greatly reduces the cost and simplifies the molding process.
优选的，帽顶的外边缘非印刷区域圆环的宽度为1-3mm，帽体一端非印刷区的直径为2-6mm，可根据帽体和帽顶整体尺寸和粘结效果改变，确保接缝处的宽度满足通过粘结剂粘贴牢固。Preferably, the width of the ring in the non-printing area of the outer edge of the cap top is 1-3 mm, and the diameter of the non-printing area at one end of the cap body is 2-6 mm, which can be changed according to the overall size of the cap body and the cap top and the bonding effect to ensure the connection. The width of the seam is enough to be firmly attached by the adhesive.
优选的，在印刷区的内表面局部或全部印刷图纹层，覆盖在所述基层和第一磁性油墨涂层和第二磁性油墨涂层的内表面，随角度变化，同一位置，第一磁性油墨层图案、第二磁性油墨层图案和图纹层图案交替显示，进一步增强防伪图案的切换效果。Preferably, a pattern layer is partially or completely printed on the inner surface of the printing area, covering the base layer and the inner surface of the first magnetic ink coating and the second magnetic ink coating. As the angle changes, at the same position, the first magnetic The ink layer pattern, the second magnetic ink layer pattern and the graphic layer pattern are alternately displayed, which further enhances the switching effect of the anti-counterfeiting pattern.
基层的内表面局部印刷UV防伪层，优选的与磁性油墨层位置不重叠；在帽顶和帽体的非印刷区的基层的外表面涂覆或印刷装饰层或防伪功能层，使得塑封整体更加美观。The inner surface of the base layer is partially printed with a UV anti-counterfeiting layer, preferably not overlapping the position of the magnetic ink layer; the outer surface of the base layer in the non-printing area of the cap top and the cap body is coated or printed with a decorative layer or an anti-counterfeiting functional layer, which makes the overall plastic seal more beautiful.
为了方便使用者正常情况使用下更容易打开防伪塑封，在筒型帽体的中部的内侧壁上横向粘结有撕拉带，并且其一端的撕拉头在露出于外部。使用时，从撕拉头处用力于撕拉带即可轻易的打开防伪塑封，不仅方便快捷的打开防伪塑封，而且打开后防伪塑封从中部被撕坏，防止仿冒，进一步提高防伪塑封的防伪性能。In order to facilitate the user to easily open the anti-counterfeiting plastic seal under normal use, a tear tape is laterally bonded to the inner side wall of the middle part of the cylindrical cap body, and the tear head at one end is exposed to the outside. When in use, the anti-counterfeiting plastic seal can be easily opened from the tearing head by applying force to the tearing tape. It is not only convenient and quick to open the anti-counterfeiting plastic seal, but also the anti-counterfeiting plastic seal is torn from the middle after opening, preventing counterfeiting and further improving the anti-counterfeiting performance of the anti-counterfeiting plastic seal. .
优选的，所述帽顶的基层选自热不收缩的PVC、PET、BOPP薄膜中的一种或几种的复合体，所述帽体的基层选自热收缩PVC、PET薄膜中的一种或几种的复合体，所述帽体的底边缘具有橫向撕裂线或竖向撕裂线，使用时，将筒型防伪塑封套在包装瓶的瓶口上，撕裂线刚好位于瓶盖的下方，防伪帽体受热收缩后，相对于包裹瓶盖的上部帽体，底部帽体收缩的更厉害，向内凹后仅仅包裹瓶颈，因此若想拔掉防伪塑封，必定会施加外力使防伪塑封底部口径最小位置首先松动，而施加的外力同时也会使防伪塑封的底部沿撕拉线裂开，防伪塑封被破坏，无法再次使用，因此可防止不法分子想尽办法无损拔出而恶意的使用。Preferably, the base layer of the cap top is selected from one or more composites of heat-not shrinkable PVC, PET, and BOPP films, and the base layer of the cap body is selected from a heat-shrinkable PVC, PET film. or several composites, the bottom edge of the cap body has a transverse tear line or a vertical tear line, when in use, a cylindrical anti-counterfeiting plastic package is sleeved on the bottle mouth of the packaging bottle, and the tear line is just located on the bottle cap. Below, after the anti-counterfeiting cap body is heated and shrunk, the bottom cap body shrinks more than the upper cap body wrapping the bottle cap. After concave inward, only the bottle neck is wrapped. Therefore, if you want to pull out the anti-counterfeiting plastic seal, an external force must be applied to make the anti-counterfeiting plastic seal. The smallest position of the bottom diameter will be loosened first, and the applied external force will also cause the bottom of the anti-counterfeiting plastic seal to crack along the tear line, and the anti-counterfeiting plastic seal will be damaged and cannot be used again.

具体实施方式Detailed ways
为了更清楚的说明本发明的内容，将结合附图1-8和具体实施例详细说明。In order to illustrate the content of the present invention more clearly, a detailed description will be given in conjunction with the accompanying drawings 1-8 and specific embodiments.
实施例1Example 1
如图1所示，本实施例的一种景变防伪结构，最外层为基层51，所述基层51的局部内表面具有第一磁性油墨涂层52，在所述第一磁性油墨涂层52和所述基层51的局部内表面上具有第二磁性油墨涂层53，这样在基层51上形成四块区域：两层磁性油墨重叠区、单独第一磁性油墨涂层52、单独第二磁性油墨涂层53以及无磁性油墨区。所述第一磁性油墨涂层52的第一磁性颜料片的定向方向与基层51的夹角为15°，第一磁性颜料片的厚度为1μm，直径尽可能的集中，平均为20μm，排列间距为1～3μm+20×cos15°μm=20.3～22.3μm，本实施例为20.5μm；所述第二磁性油墨涂层53上的第二磁性颜料的定向方向与基层51的夹角为-75°，即与第一磁性颜料片的夹角为90°，厚度为1μm，直径为20μm，排列间距为6～14μm+20×cos75°μm=11.2～19.2μm，本实施例为19.2μm。As shown in FIG. 1 , in a scene-change anti-counterfeiting structure of this embodiment, the outermost layer is a
上述景变防伪结构中每层的磁性颜料片均为微米结构，且彼此平行排列，形成了上百万个微反镜，在可见光下，随着光线9的变化或观察视线的变化或防伪结构位置的变化，呈现空中变脸效果。如图1-3所示，防伪结构和观察者角度保持不变，改变光照角度。The magnetic pigment flakes of each layer in the above-mentioned landscape change anti-counterfeiting structure are all micro-structures and are arranged in parallel with each other, forming millions of micro-mirrors. The change of position, showing the effect of changing face in the air. As shown in Figure 1-3, the anti-counterfeiting structure and the observer's angle remain unchanged, and the illumination angle is changed.
如图1所示，光线9从上方照射到景变防伪结构，对于两层磁性油墨重叠区，由于光线9照射到第一磁性颜料片上被反射后射向人眼，第二磁性油墨涂层53的图案被遮挡，仅清晰显示所述第一磁性油墨涂层52的图案（如图4所示）；同样对于单独第一磁性油墨涂层52区仅清晰显示所述第一磁性油墨涂层51的图案（如图4所示）；对于单独第二磁性油墨涂层53，由于光照角度以及所述第二磁性颜料片尺寸、角度和间隔设置（优选的增加了6-14μm），使得大部分光线9从所述第二磁性颜料片的间隙透过，且能观察到的第二磁性颜料片的宽度仅为20×cos75°=5.2μm，远小于第一磁性颜料片可观察到的宽度（约为20×cos15°μm=19.3μm），由于百叶窗原理，在每片颜料片足够小且观察距离足够远的情况下，肉眼无法看到第二磁性油墨涂层53的图案。因此当光线9从上方照射到景变防伪结构时，仅清晰显示所述第一磁性油墨涂层52的图案，例如如图4所示的图案—字母A。As shown in FIG. 1 , the
如图2所示，当光线9垂直膜材照射到景变防伪结构上时，由于在原有间隔的基础上，第二磁性颜料片的间隔增加6～14μm，增加了第二磁性颜料片的透光性，使得大部分光线9从所述第二磁性颜料片的间隙透过，使得对于两层磁性油墨重叠区以及单独第一和第二磁性油墨涂层，无法看到第二磁性油墨层53图案，仍可清晰看到第一磁性油墨涂层52的图案，如图4所示的图案—字母A。As shown in FIG. 2 , when the
如图3所示，当光线9从下方的低略角度倾斜照射到景变防伪结构时，例如与第一磁性颜料片平行，由于光线9照射角度以及所述第一磁性颜料片尺寸、角度和间隔设置（优选的增加1-3μm），大部分光线9从所述第一磁性颜料片的间隙透过后，照射到第二磁性颜料片上被反射后射向外人眼，因此肉眼无法看到第一磁性油墨涂层52的图案，对于两层磁性油墨重叠区、单独第一和第二磁性油墨涂层，无法显示第一磁性油墨层52的图案，仅清晰显示所述第二磁性油墨涂层53图案，例如如图6所示的图案—字母B。As shown in FIG. 3 , when the
在光线9从图2所示的垂直照射角度向图3所示的斜向上照射角度改变的过程中，存在一个角度区间，例如10-15°左右的范围内，所述第一磁性颜料片和第二磁性颜料片的表面的反射光均射向人眼，因此同时显示两层的图案，如图5所示的图案—重叠的字母A和字母B。In the process of changing the light 9 from the vertical irradiation angle shown in FIG. 2 to the oblique upward irradiation angle shown in FIG. 3 , there is an angle interval, for example, in the range of about 10-15°, the first magnetic pigment flakes and The reflected light on the surface of the second magnetic pigment flakes is directed to the human eye, thus simultaneously displaying a pattern of two layers, such as the pattern shown in FIG. 5—the overlapping letters A and B.

在所述第一磁性油墨涂层52和基层51的局部表面涂布第二磁性油墨涂层53，所述第二磁性颜料涂层53的油墨包括厚度为0.5-3μm，直径为10-30μm的第二磁性颜料片和可固化的透明粘结剂，将所述第二磁性颜料片通过磁场定向为第二角度，然后干燥，将所述第二颜料片固定在第二角度位置，第二磁性颜料片排列间隔=第二磁性颜料片直径×cos（25～85°）μm；A second
第一磁性颜料片与基层夹角为+10～+60°，第二磁性颜料片与第一磁性颜料片的夹角为85～95°之间的任一角度，或者说第二磁性颜料片与基层的夹角为-25～-85°。The included angle between the first magnetic pigment flake and the base layer is +10 to +60°, the included angle between the second magnetic pigment flake and the first magnetic pigment flake is any angle between 85 and 95°, or the second magnetic pigment flake The included angle with the base layer is -25 to -85°.
本文所述的第一磁性油墨涂层和第二磁性油墨涂层通过涂布方法，优选通过选自丝网印刷，轮转凹版印刷和苯胺印刷的印刷方法独立地施加。The first magnetic ink coating and the second magnetic ink coating described herein are applied independently by a coating method, preferably by a printing method selected from screen printing, rotogravure printing and flexographic printing.
尽管本文所述的第一磁性油墨涂层和第二磁性油墨涂层仍足够湿或柔软，使得片状颜料可以移动和旋转，但它们独立地经受磁场作用以实现颗粒的取向。定向片状颜料的步骤包括以下步骤：将各个油墨涂层暴露于由磁性组件产生的确定的磁场，从而使片状颜料沿磁场的磁力线定向，从而将其定向在各自的角位置上。磁场可以为现有技术中使用的任何形式的磁定向装置产生磁场。While the first and second magnetic ink coatings described herein are still sufficiently wet or soft to allow movement and rotation of the platelet pigments, they are independently subjected to the magnetic field to effect orientation of the particles. The step of orienting the flake pigments includes the steps of exposing each ink coating to a defined magnetic field generated by a magnetic assembly to orient the flake pigments along the magnetic field lines of the magnetic field, thereby orienting them at respective angular positions. The magnetic field can generate a magnetic field for any form of magnetic orientation device used in the art.
如本文所述，将本文所述的第一磁性油墨涂层和第二磁性油墨涂层独立地干燥以固定片状颜料的取向。因为辐射固化有利地导致油墨涂层的粘度瞬时增加并且使片状颜料瞬时固定在它们各自的角位置，所以干燥步骤优选通过包括紫外-可见（UV-Vis）光辐射固化的辐射固化或通过电子束辐射固化，更优选通过UV-Vis光辐射固化。辐射固化是特别优选的，而UV-Vis光辐射固化是更优选的，因为这些技术有利地导致非常快速的固化过程，并因此大大减少了两层磁性防伪结构的制备时间。As described herein, the first magnetic ink coating and the second magnetic ink coating described herein are independently dried to fix the orientation of the platelet pigment. The drying step is preferably by radiation curing including ultraviolet-visible (UV-Vis) light radiation curing or by electronic Curing by beam radiation, more preferably by UV-Vis light radiation. Radiation curing is particularly preferred, and UV-Vis light radiation curing is more preferred, since these techniques advantageously result in a very fast curing process and thus greatly reduce the preparation time of the two-layer magnetic security structure.
对于其中干燥步骤通过UV-Vis光辐射固化独立进行的实施方案，本文所述的第一磁性油墨涂层和第二磁性油墨涂层独立地包含一种或多种可固化化合物和一种或多种光引发剂。可通过调节油墨中颜料片的浓度/粘稠度从而调节颜料片的排布间隙，第一颜料片的间隙略大于颜料片的直径，第二颜料片的间隙小于颜料片的直径，配合二者角度和厚度参数，从而使得当采用与第一磁性油墨涂层52上的颜料片的正面呈交叉的光线9照射下（如图1和图2），第一磁性油墨涂层52对第二磁性油墨涂层53的遮挡性好，清晰显示第一磁性油墨涂层52图案，而当以从与第一磁性油墨涂层52上的颜料片平行开始的低略光线9照射时（如图3），第一磁性油墨涂层52对第二磁性油墨涂层53几乎没有遮挡，第二磁性油墨涂层53的可见性好。For embodiments wherein the drying step is performed independently by UV-Vis light radiation curing, the first and second magnetic ink coatings described herein independently comprise one or more curable compounds and one or more a photoinitiator. The arrangement gap of the pigment flakes can be adjusted by adjusting the concentration/viscosity of the pigment flakes in the ink. The gap of the first pigment flake is slightly larger than the diameter of the pigment flake, and the gap of the second pigment flake is smaller than the diameter of the pigment flake. angle and thickness parameters, so that when irradiated with
