る顕色インキも用いられるに至っている。[Prior Art] As disclosed in Japanese Patent Publication No. 49-27134, developing inks conventionally used for carbonless copying paper include aromatic carboxylic acids or their anhydrides, metal compounds, and alkaline inks. A color developing ink made of a substance is shown, and this color developing ink is used by being printed and applied to the area where copying is required, and is carried out by gravure or flexography. However, in gravure and flexography, a large amount of low-density developer ink must be applied in order to obtain the necessary amount of developer for color development, resulting in large amounts of solvent seeping into the paper immediately after printing. , there was a risk that the dye inside the capsule would react if it came into contact with the capsule on the back side of the paper. Therefore, color developer inks composed of a color developer, resin, and silicone oil have come to be used as color developer inks that can be printed by letterpress printing and offset printing.

When you touch a surface coated with colored ink, it feels sticky, and
Dust will stick to it.
