摘要

A photocurable resin composition comprising: (a) a conjugated diene polymer or copolymer containing functional groups (I) and (II) and having a number-average molecular weight of 500 to 5,000 and a vinyl content of at least 50 mole %, wherein R1 represents a C1 to C20 hydrocarbon residue which may contain a heteroatom, R2 and R3 each represents a hydrogen atom or a methyl group, and R4 represents a C2 to C20 hydrocarbon residue which may contain a heteroatom, and (b) a photopolymerization initiator.
