PURPOSE:To obtain a photopolymerizable compsn. having high sensitivity to the visible light by incorporating a combination of a specified aromatic amino compd. and an isoalloxazine type compd. as a photopolymerization initiator in a high-boiling additionally polymerizable compd. CONSTITUTION:An intended photopolymerizable compsn. is obtained by mixing (A) a additionally polymerizable compd. having >=100 deg.C b.p. at normal pressure, such as diethyleneglycol diacrylate or divinyl phthalate with (B) an aromatic amino compd. represented by formula I (R1, R2 are each 1-3C alkyl; X is formyl, carboxy, acyl, or the like; and (n) is 1-3), such as 4-dimethylaminobenzaldehyde or 4-dimethylacetophenone, and (C) a compd. having an isoalloxazine structure represented by formula II (R3, R4 are each H, methyl, or ethyl), such as riboflavin or riboflavin tetrabutyrate. |
