<p>PROBLEM TO BE SOLVED: To obtain the photocurable colored composition hardly impregnable with an alkali metal even in the case of being exposed to alkali by using a composition composed of a specified weight of a composition formed by adding a fine pigment powder and a photoreactivity donor into a water-soluble copolymer made from each specified monomer, and a specified amount of polyisocyanate compound. SOLUTION: This photocurable colored composition comprises the composition in an amount of 70-99.99 weight% formed by dding the fine pigment powder and a photoreactivity donor into the water-soluble copolymer made from each of the monomers represented by formulae I-IV, and the polyisocyanate compound in an amount of 0.01-30 weight%. In formulae I-IV, (n) is 1 or 2; each of R<1> , R<3> , and R<4> is an H atom or a methyl group; R<2> is an H atom or a carboxyl group; and X is an ethylene or propylene group.</p> |
