Abstract
An object of the present invention is to provide a photocurable resin composition having a high curing degree after irradiation with light while maintaining cured material characteristics such as high extensibility and high strength. Provided is a photocurable resin composition including the following ingredients (A) to (C): ingredient (A): a polyisobutylene resin containing one or more (meth)acryloyl groups and a —[CH2C(CH3)2]— unit; ingredient (B): ingredient (b1): an acrylate monomer having an alicyclic hydrocarbon group having 5 to 25 carbon atoms, and ingredient (b2): an acrylate monomer having a linear or branched alkyl group having 11 to 30 carbon atoms; and ingredient (C): a photo-radical polymerization initiator.
