ABSTRACT:
A photocurable resin composition comprising (a) 100 parts by weight of a modified resin prepared by reacting an .alpha.,.beta.-unsaturated dicarboxylic acid anhydride adduct having a softening point ranging from 70.degree. to 200.degree. C. and derived from a conjugated diene polymer or copolymer having a number average molecular weight of 500 to 5000 and a vinyl group content of 50 mole % or above, with an .alpha.,.beta.-unsaturated monocarboxylic acid ester having a specific alcoholic hydroxy group to open at least 10 mole % of the acid anhydride rings present in the adduct, (b) inorganic or organic powder having an average particle diameter of not larger than 5 .mu.m or inorganic powder grafted with a hydrocarbon residue, and (c) a photopolymerization initiator.
