Abstract:
1. A photosensitive resin composition comprising: [A] a compound having a carbon-carbon unsaturated double bond and carboxyl group, which is obtained by allowing a bisphenol type epoxy compound and an unsaturated monocarboxylic acid to react, and then allowing a polybasic acid anhydride to undergo addition reaction with part or all of secondary hydroxyl groups of the reaction product; [B] a urethane (meth)acrylate compound having a structure derived from a polycarbonate-polyol structure, wherein said urethane (meth)acrylate compound [B] has no carboxyl groups; [C] a polymerizable compound having a carbon-carbon unsaturated double bond; and [D] a photopolymerization initiator.
