PURPOSE:To provide a composition having excellent chemical resistance, water- resistance and mechanical strength, etc., and composed of a side-chain unsaturated resin having (meth)acryloyl group on side chain terminal through a skeleton structure of epoxy resin, a (meth)acrylate monomer and a photo-polymerization initiator. CONSTITUTION:The objective photo-setting resin composition is composed of (A) a side-chain unsaturated resin of formula [A is main chain composed of a copolymer resin of a vinyl monomer and a (meth)acryloyl group; R is H or CH3; Y is an epoxy resin residue obtained by forming an ester bond by ring-opening addition reaction of an epoxy group in the molecule with carboxyl group and removing said ester bond from the reaction product], (B) a monomer having one or more (meth)acryloyl groups in one molecule (e.g. phenoxyethyl acrylate) and (C) >=0.1% photo-polymerization initiator (e.g. benzophenone). The composition is useful in the field of paint, adhesive, cast product and FRP.
