れることがあり、使用上の問題点となっている。2. Description of the Related Art Adhesives made of synthetic resin emulsions, such as acrylic emulsions and vinyl chloride emulsions, are known as adhesives used for general office work such as laminating paper. Most are colorless and transparent. Therefore, when it is applied on paper, the application part is difficult to understand, and the application amount may be insufficient, or conversely, the application may be excessive. In addition, the application part may be touched by a hand or the like, which is a problem in use.

る。For this reason, recently, the pH of the adhesive has been adjusted to about 10 to 13, and a pH indicator has been added to the adhesive, which has been colored. Known colored pastes are known. The reason why the color is erased after the application is to prevent the color of the paste from being seen through the paper (through strike-through) when the papers are bonded.
【０００４】しかしながら、接着剤のｐＨを１０〜１３

つまり、着色糊としての機能を果たさなくなる。また、
ｐＨ指示薬が高価であり、かつ色の種類も少ない問題点
がある。[0004] However, the pH of the adhesive is 10 to 13
When adjusted to such an extent, not only does the stability of the paste deteriorate, but also the color may fade or fade over time.
That is, the function as a colored paste is not fulfilled. Also,
There is a problem that the pH indicator is expensive and there are few kinds of colors.
【０００５】そこで本発明は、糊の安定性が問題になる
ことがなく、安価で色数も豊富に揃えることができる紙
貼り合わせ用の着色糊を提供することを目的とする。Accordingly, the present invention provides an inexpensive paper which can be provided in a wide variety of colors without inconvenience of the stability of the paste.
An object of the present invention is to provide a colored paste for bonding .

ｐｍ添加して紙貼り合わせ用の着色糊とする。In order to achieve the above object, the present invention relates to an adhesive made of an emulsion of a synthetic resin such as an acrylic emulsion or a vinyl chloride emulsion, and a coloring agent made of a dye or a pigment is added in an amount of 5 to 300 p.
pm is added to form a colored paste for paper bonding .

を透過して見える裏抜けを防止することができる。Since a dye or a pigment is used as a coloring agent, the number of colors is abundant and the cost is low. Further, there is no need to adjust the pH of the adhesive and the stability of the adhesive does not become a problem. And
Since the addition amount of the colorant is 5 to 300 ppm, the adhesive is colored and functions as a colored paste, and is not excessively colored, so that when the paper is pasted, the color of the paste appears to pass through the paper. Strikethrough can be prevented.

が生じないと判断してよい。In the strike-through test, when papers are pasted together with a paste to which a predetermined coloring agent has been added, the color difference ΔEab * between the paste-coated portion and the non-coated portion is measured with a color difference meter. evaluated. The color difference ΔEab * is obtained from the lightness index L * and the chromaticness chromaticity indexes a * and b *. If the numerical value of the color difference ΔEab * is 5.0 or less, the two colors are Visually, the colors are determined to be the same. That is, it may be determined that strikethrough does not occur.

Crimping is performed with a 2 kg roller of Z0237 standard. Then, it is left in a dryer at 60 ° C. for 24 hours, and as described above,
The color difference ΔEab * of the portion where the paste was applied and the portion where the paste was not applied was measured with a color difference meter. Table 1 shows the results.

ば、裏抜けは生じない。Although the measured values vary due to the uneven distribution of small holes in the paper and the effect of the permeability of the colorant, the color difference ΔEab * is 5. if the amount of the colorant added is 300 ppm.
0 or less, no strikethrough occurs. However, when the amount of the coloring agent added is 500 ppm, the numerical value of the color difference ΔEab * may be 5.0 or more, and strikethrough occurs. Therefore, the amount of the coloring agent needs to be 300 ppm or less. When the colorant is a pigment, the color difference is smaller than that of the dye.
Since the value of Eab * is about 0.5 to 1.0 lower,
Even when the colorant is a pigment, if the addition amount is 300 ppm or less, strikethrough does not occur.

じるためである。Next, the results of the coloring test will be described. In the coloring test, the color difference ΔEab * between the portion where the colored paste was applied to the paper and the portion where the colored paste was not applied was evaluated by a sensory test. The reason why the sensory test is also used is that the confirmation of the coated surface is performed almost instantaneously, and a problem occurs only with the color difference ΔEab * by the colorimeter which is assumed to be confirmed slowly.

Ｅab＊は５を越えるものの方が少ない。つまり、測色計

必要となる。As can be seen from Table 2, when the amount of the colorant added is 10 ppm, the color difference ΔEab * is almost 5 or more, but when the amount of the colorant added is 5 ppm, the color difference ΔEab * is 5 ppm.
Eab * is less when it exceeds 5. That is, according to the test result by the colorimeter, the amount of the coloring agent to be added is 10 ppm or more.

３に示す。However, as described above, since a problem occurs only with the color difference ΔEab * by the colorimeter on the premise of checking slowly, a sensory test was conducted. Next, the results will be described. A colored paste obtained by adding a predetermined coloring agent to about 10 B4 size PPC high-quality paper is about 1.3 mm in width,
It is applied randomly at 5 locations per sheet with a length of 10 mm and a film thickness of about 20. Then, the number of persons who could find the part applied on the ten sheets of paper for 10 seconds per one person was examined, and this was defined as the discovery probability. In other words, 5 (locations)
The number of points that could be found out of × 10 (sheets) × 10 (persons) = 500 points was checked and displayed in%. Table 3 shows the results.

That is, the amount of the coloring agent added is 5 pp.
When it is at least m, it can function as a colored paste. It should be noted that, even when the colorant is a pigment, another test has confirmed that when the added amount is 5 ppm or more, the colorant can also function as a color paste.

The coloring paste used for the coloring is an adhesive consisting of an emulsion of a synthetic resin such as an acrylic emulsion or a vinyl chloride emulsion, and a coloring agent consisting of a dye or a pigment being 5-300.
Since ppm is added to form a colored paste, there is no problem with the stability of the paste, and it is possible to provide a colored paste that is inexpensive and can be provided in a large number of colors.
