PROBLEM TO BE SOLVED: To obtain high pixel hardness in a simple process by incorporating a coloring agent, an alkali-soluble resin, polyfunctional monomers, a photopolymn. initiator and a compd. having specified numbers or more of epoxy groups. SOLUTION: This compsn. contains a coloring agent, an alkali-soluble resin, a polyfunctional monomer, a photopolymn. initiator and a compd. having two or more epoxy groups. As for the coloring agent, either an org. coloring agent or an inorg. coloring agent or both of these can be used, and practically, an org. pigment is preferably used. As for a preferable alkali-soluble resin, a copolymer of an ethylenrically unsatd. monomer having one or more carboxyl groups and another copolymerizable ethylenrically unsatd. monomer is preferably used. The polyfunctional monomer has two or more polymerizable ethylenrically unsatd. bonds. As for the compd. having two or more epoxy groups, for example, a bisphenol A epoxy resin and a hydrogenated bisphenol A epoxy resin can be used. |
