Abstract:
1. A photocurable resin composition comprising a cationic polymerizable compound (A), an acrylic resin (B), and a cationic photopolymerization initiator (C), wherein the cationic polymerizable compound (A) is used in combination of a compound containing an oxetanyl group and a compound containing an epoxy group, the acrylic resin (B) is a copolymer of a radical polymerizable monomer having a cationic polymerizable functional group and a second radical polymerizable monomer, said second radical polymerizable monomer is at least one selected from the group consisting of styrene, α-methylstyrene, vinyl acetate, and a (meth)acrylate whose ester group includes a methyl group, an ethyl group, an isopropyl group, a normal butyl group, an isobutyl group, a tert-butyl group, a cyclohexyl group, a benzyl group, or an isobornyl group, and the content of the component (A) is 30 to 95 parts by mass and the content of the component (B) is 5 to 70 parts by mass, based on 100 parts by mass of the total amount of the components (A) and (B).
