A photopolymerizable composition comprising a poly- merizable compound component and a photopolymerization initiator, characterized in that (a) a bifunctional (meth)acrylic (thio)ester containing a sulfur atom in the molecule and (b) a (meth)acrylate represented by the general formula (1) and/or a bifunctional (meth)acrylic ester having a urethane linkage are contained as the polymerizable compound component: (1) wherein R1 and R2 are each independently hydrogen or methyl; R3 and R4 are each independently alkyl, aralkyl, aryl, or halogeno; m and n are each an integer of 0 to 2; X1 is alkylidene having one to three carbon atoms; and Y1 and Y2 are each independently poly(oxyalkylene) with the proviso that at least one of Y1 and Y2 is hydroxylated poly(oxyalkylene). |
