PURPOSE:The titled composition having improved adhesivity to metals, heat resistance and insulating properties, comprising a specific unsaturated alicyclic epoxy ester compound, a polymerizable vinyl monomer, a photopolymerization initiator, a carboxyl end group-containing butadiene polymer, etc. as essential components. CONSTITUTION:(A) An unsaturated alicyclic epoxy ester compound (e.g., compound shown by the formula, etc.) obtained by reacting 1 equivalent epoxy group of an alicyclic epoxy compound containing >=two or more epoxy groups in one molecule with 0.5-1.1 equivalent (meth)acrylic acid is blended with (B) a polymerizable vinyl monomer (e.g., methyl acrylate, etc.), (C) 0.1-10wt% based on the components A+B of a photopolymerization initiator (e.g., benzoinbenzoin methyl ether, etc.), and (D) 0.1-2wt% based on the components A+B of a carboxyl end group-containing butadiene polymer or a butaene/ acrylonitrile copolymer as essential components in a weight ratio of the component A/B of preferably 50/50-90/10, to give the aimed composition.
