Abstract:
A photopolymerizable composition comprising:(A) 100 parts by weight of a mixture of (meth)acrylic acid ester monomers, comprising:(a) from 0 to 60% by weight, based on the total weight of the mixture of (meth)acrylic acid ester monomers, of a compound having at least 3 (meth)acryloyl groups,(b) from 20 to 90% by weight, based on the total weight of the mixture of (meth)acrylic acid ester monomers, of a compound having two (meth)acryloyl groups,(c) from 5 to 30% by weight, based on the total weight of the mixture of (meth)acrylic acid ester monomers, of a compound having one (meth)acryloyl group and containing no hydroxyl group, and(d) from 1 to 20% by weight, based on the total weight of the mixture of (meth)acrylic acid ester monomers, of a compound having one (meth)acryloyl group and containing at least one hydroxyl group(B) from 0.1 to 5 parts by weight of a surfactant having a perfluoroalkyl group and represented by the general formula (1)CF.sub.3 (CF.sub.2).sub.n AM (1)wherein A represents --CO.sub.2 -- or --SO.sub.3 --, M represents an alkali metal, and n is an integer of 3 to 9, and(C) from 0.2 to 10 parts by weight of a photopolymerization initiator.
