紙に発色像を得ることができるものである。Pressure-sensitive copying paper uses an electron-donating coloring agent (hereinafter referred to as coloring agent) such as crystal violet lactone and an electron-accepting coloring agent (hereinafter referred to as coloring agent) such as a polyvalent metal salt of an aromatic carboxylic acid. This paper utilizes the color reaction of When the surface is pressed with a typewriter or the like, a colored image can be obtained on the underlying paper.

ある。Furthermore, if you wish to make multiple copies, you can make multiple copies by inserting the necessary number of inner sheets coated with a coloring agent on the front side of the base paper and microcapsules on the back side between the upper and lower sheets. You can get a copy. Further, as a type of pressure-sensitive copying paper, there is a so-called single-piece pressure-sensitive copying paper in which the above-mentioned microcapsules and a coloring agent are formed as a laminated or mixed layer.

ヒクルと共にインキ化し、これを呈色剤塗布面に印刷す
る方法が採られている。In order to prevent color development in specific areas of pressure-sensitive copying paper, a method has been proposed in which a desensitizer that inhibits color reaction is made into ink with an appropriate vehicle, and this is printed on the surface coated with the color former. It is taken.

とにより行われるが、実用上、種々の問題が発生してい
る。Desensitized printing is carried out by printing with a desensitized ink containing a desensitizing agent, pigment, vehicle, etc. using a letterpress, offset, or flexographic method, but various problems arise in practice.
例えば、光が当たったり、熱が加わったり或いは高湿度
条件下におかれた場合には減感効果が低下したりする。For example, if exposed to light, heat, or placed under high humidity conditions, the desensitizing effect may be reduced.
また所望の用紙の特定部分に塗布された減感剤が隣接す
る他の用紙の複写所望部分に転移し、必要箇所以外に減
感効果が波及するという現象がある。Furthermore, there is a phenomenon in which the desensitizer applied to a specific portion of a desired sheet of paper is transferred to the desired portion of another adjacent sheet of paper, and the desensitizing effect spreads to areas other than the necessary portions.

提案されている。In addition to these problems, the use of photocurable desensitized inks has also become widespread due to improved ink setting properties, increased printing speed, prevention of solvent odor, and the like. This photocurable desensitizing ink is known, for example, in Japanese Patent Publication No. 55-10397 and Japanese Patent Application Laid-open No. 52-52.

はないのが現状である。However, radical polymerization type desensitized inks have problems such as the ink's tendency to thicken over time (short bond life), long curing time, and curing reactivity is easily affected by pigments. However, the current situation is that the results are not necessarily satisfactory.

供することである。Compared to the conventional photo-curing type desensitized ink described above, the present invention has a less tendency to thicken over time (longer bond life), a shorter curing time by light irradiation, and a curing reactivity that depends on the pigment. It is an object of the present invention to provide a photocurable desensitizing ink for pressure-sensitive copying paper, which has excellent adhesion to paper without being affected.
