PURPOSE:To obtain the titled composition capable of dispaying various kinds of colors and having a good durability against a heat and a moisture, and having a good shelf-life by incorporating an org. compd. having an electron donative coloration property and an optical activator selected from a sulfonium salt, a phosphonium salt and an iodonium salt and a compd. having an alcoholic hydroxyl group as an essential component. CONSTITUTION:The titled composition comprises the org. compd. A having the electron donative coloration property, at least one of the photoactivators B selected from the sulfonium salt shown by formula I, the phosphonium salt shown by formula II, and the iodonium salt shown by formula III and the compd. C having the alcoholic hydroxyl group as the essential component. The titled comp. having the good durability against a heat and a moisture, and having no odor and no generation of a gas and a bubble by irradiating a light is obtd. by incorporating to the org. compd. A having the electron donative coloration property, the sulfonium salt, the phosphonium salt or the iodonium salt. By incorporating the compd. C having the alcoholic hydroxyl group to said components A and B, the excellent property capable of simultaneously coloring said compd. A by irradiating the light is obtd. |
