【発明の詳細な説明】本発明はラベル用紙に関し、更には、電子写真複写機で
画像形成するに適したラベル用紙に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to label paper, and more particularly to label paper suitable for image formation with an electrophotographic copying machine.
近来、ラベル用紙への複写を電子写真複写機を用いて行
われることが普及してきており、これに伴い普通紙同様
に電子写真複写機で複写できるラベル用紙の要求が高ま
っている。BACKGROUND ART In recent years, it has become common to use electrophotographic copying machines to copy onto label paper, and as a result, there has been an increasing demand for label paper that can be copied using electrophotographic copying machines in the same way as plain paper.

ワが生じ寿いだけの紙強度が必須である。As transfer paper for electrophotographic copying machines, it is especially important to use paper that is prone to curling, which can cause paper jams due to poor paper feeding and separation, as well as paper that has a limited shelf life due to folded edges and curly edges caused by feeding multiple sheets. Strength is essential.

料（・ソルゾ）の特性上、吸湿伸びが大きく１境カール

め電子写真複写機にて使用するには問題が多かった。Conventionally available paper sheets use glassine paper or kraft paper ('J = quality paper, foam paper, etc.) for the release paper, but the former has a manufacturing method and materials (... Due to the characteristics of ``Sorzo'', it has a large moisture absorption elongation and curls significantly at one border, and the latter also causes curls and does not have sufficient paper strength, so it has many problems when used in electrophotographic copying machines.
本発明の目的は、前記欠点を解決して普通紙同様に重子

であり、本発明者は鋭意検討を重ねた結果、本発明を完
成した。The purpose of the present invention is to solve the above-mentioned drawbacks and to develop a base paper for label paper that can be used in Shigeko Photo Machines in the same way as plain paper.As a result of extensive studies, the present inventor has completed the present invention. did.
即ち、本発明のラベル用紙は、表２１原紙に剥離層及び

ことを特徴とするものである。That is, the label paper of the present invention is a label paper that is integrated by pasting the back side base paper to the base paper of Table 21 through a release layer and an adhesive layer.
Contains 10 layers of melamine resin, and further contains melamine resin in the base paper.
It is characterized by containing urea in the release layer and/or the adhesive 1.
本発明のラベル用紙の構造は、従来のものと同様に表面
原紙及び裏面原紙の２層を成しているが、原紙を抄紙す

又は含浸している。The structure of the label paper of the present invention is similar to conventional ones, consisting of two layers, a front base paper and a back base paper, but when the base paper is made, melamine resin is added internally in an amount of 2 to 10% by weight of the base paper pulp. Or impregnated.

ことで、前記悪臭を放すホルムアルデヒドと尿素とが瞬
時反応して無臭の尿素−ホルムアルデヒド化合物が生成
するので臭気の問題は解決された。Because the base paper contains a large amount of melamine resin, it has strong fiber bonds, high rigidity, and less curling. However, since the fixing temperature of Copy Sakaki is usually as high as 150 to 300 degrees Celsius, a portion of the melamine resin thermally decomposes and generates formaldehyde, giving off a bad odor.
By applying it with a coating material such as, or blending it with the adhesive or surface treatment agent of label paper, or both, the formaldehyde and urea that emit a bad odor react instantly to form an odorless urea-formaldehyde compound. So the odor problem was solved.
それから、前述したように本発明のラベル用紙は表面紙

好ましい、。Then, as mentioned above, the label paper of the present invention consists of a front paper and a back paper, and a surface treatment agent is applied to one side of the back paper, dried and hardened to form a release layer, and an adhesive is further applied to the front paper. However, the amount of melamine resin applied in the inner surface and size press (1 to 4 f, /rr?) is a large amount on the front paper, and if it is applied, it will damage the adhesive and cause the front paper and back paper to separate. Therefore, it is preferable to add a large amount to the back paper.
次に、原紙の厚さは、電子写真複写機との適合性から、
表面紙は６０〜７５μ翫裏面紙は４５〜６５μｍとなる
ように抄紙されることが好ましい。Next, the thickness of the base paper is determined based on compatibility with the electrophotographic copying machine.
It is preferable that the paper is made so that the front paper has a thickness of 60 to 75 μm and the back paper has a thickness of 45 to 65 μm.

使用するＫは問題がある。The basis weight, thickness, and rigidity of each of the above label papers were determined, and the suitability for paper passing and the presence or absence of odor were examined using a dry copying machine (Ricoh FT6400) at a fixing temperature of 190°C. The results shown in Figure 3 were obtained.
and atmospheric humidity (sword, 0... indicates no paper passing problem x... indicates impossible paper passing)'' As is clear from the above results, the label paper of the present invention is superior to the conventional label paper. (Comparative Examples 2 and 3), it has high rigidity, and the difference (absolute value and ratio) between the vertical and horizontal directions is small, and it has excellent paper threading suitability similar to plain paper, and it prevents edge folding. Almost no copy wrinkles occurred. Comparative Example 1
(No urea added) K has a bad odor and is problematic when used in electrophotographic copying machines.
