Claim:
A photocurable resin composition, comprising: a photopolymerization initiator comprising two oxime ester groups; a resin comprising a carboxyl group; a compound comprising two or more ethylenically unsaturated groups; and a thermocurable resin, wherein the photopolymerization initiator is an oxime ester compound represented by formula (1), where R 1 represents a hydrogen atom, an alkyl group having 1 to 17 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, a phenyl group, a phenyl group substituted with an alkyl group having 1 to 17 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, an amino group, or an alkylamino group or a dialkyl amino group with an alkyl group having 1 to 8 carbon atoms, or a naphthyl group substituted with an alkyl group having 1 to 17 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, an amino group, an alkylamino group or a dialkyl amino group with an alkyl group having 1 to 8 carbon atoms; R 2 and R 3 each represent a hydrogen atom, an alkyl group having 1 to 17 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, a halogen group, a phenyl group, a phenyl group substituted with an alkyl group having 1 to 17 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, an amino group, or an alkylamino group or a dialkyl amino group with an alkyl group having 1 to 8 carbon atoms, a naphthyl group substituted with an alkyl group having 1 to 17 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, an amino group, or an alkylamino group or a dialkyl amino group with an alkyl group having 1 to 8 carbon atoms, an anthryl group, a pyridyl group, a benzofuryl group, or a benzothienyl group; Ar is a bond or represents alkylene having 1 to 10 carbon atoms, vinylene, phenylene, biphenylene, pyridylene, naphthylene, anthrylene, thienylene, furylene, 2,5-pyrrole-diyl, 4,4′-stilbene-diyl, or 4,2′-styrene-diyl; and n represents an integer of 0 to 1.
