摘要： A process for the preparation of a photocurable resin which comprises the steps of(I) (a) imidating 20 to 80 mole % of the acid arthydride groups present in an adduct prepared by the addition reaction of an .alpha.,.beta.-unsaturated dicarboxylic acid arthydride to a conjugated diene polymer or copolymer with a primary amine to produce water and an amide,(b) reacting the thus formed water as a by-product with at least a part of the remaining acid arthydride groups in said adduct to produce the succinic acid groups by opening the ring of said acid arthydride groups,(II) dehydrating the thus produced succinic acid groups by heating to cause ring closure again thereby forming acid anhydride groups and(III) reacting at least a part, preferably at least 50 mole %, of the acid anhydride rings present in the polymer with an .alpha.,.beta.-unsaturated monocarboxylic acid ester having an alcoholic hydroxyl group to conduct a half-esterification by opening the ring of said acid arthydride groups.
