PURPOSE:To enhance sensitivity to the visible light by incorporating an ethylenically unsaturated compound nongaseous at normal temperature, a specified iron allene complex, and a specified p-aminophenyl unsaturated ketone compound. CONSTITUTION:At least one of the ethylenically unsaturated compounds nongaseous at normal temperature is used for the photopolymerizable composition, and further, the iron allene complex represented by formula I and the p-aminophenyl unsaturated ketone represented by formula II are added to form the photopolymerizable composition, and in formulae I or II R is the hydrogen and the like, X is BF4 and the like, each of m and n is 0 or 1; each of R1 and R2 is H or the like; R3 is methylidyne or 1-5C alkylene-iridin group capable of forming a ring together with the carbonyl group and R4; R5 is represented by formula III; and each of R7 and R8 is H or 1-5C alkyl, thus permitting the sensitivity the visible light to be enhanced. |
