Abstract
A photocurable resin composition comprises a cationic polymerizable compound (A), an acrylic resin (B) and a cationic photopolymerization initiator (C), in which the acrylic resin (B) has a cationic polymerizable functional 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). In addition, the functional group of the acrylic resin (B) preferably contains at least one of a cyclic ether group, a vinyloxy group, an acid adduct of a vinyloxy group, and an active hydrogen group, with the active hydrogen group preferably being a hydroxyl group. The photocurable resin composition has sufficient curability and sufficient adhesiveness to rigid plastics such as polycarbonate and PET having poor adhesive property.
