<p>PURPOSE:The titled composition useful as a colored coating compound or various printing ink, capable of achieving sufficient curing independently of color concentration and film thickness, showing no change with a resin to be applied, obtained by adding a specific novel dye salt as a colorant to a photosetting resin composition. CONSTITUTION:A photosetting resin composition is blended with preferably 0.5- 5pts.wt. based on 100pts.wt. of the composition of a novel dye salt shown by the formula I (A is anionic dye; R2 and R2 are allyl, 1-6C alkyl, or H; n is 1-4). The novel dye salt shown by the formula I, for example, is prepared by dissolving or dispersing anionic dye (e.g., C.I.Acid Yellow 29, etc.) into water or a solvent, adding an allylamine shown by the formula II or its derivative to it at a normal temperature or under heating, stirring them in a neutral - weakly acidic atmosphere, filtering, drying the reaction product. EFFECT:Having improved curing rate, hardness of film surface and release resistance, causing no choling, bleeding, and migration.</p> |
