Abstract
The present invention relates to a polycarboxylic acid anhydride having a structural unit represented by the following Formula (1). The present invention provides a novel polycarboxylic acid anhydride. When the polycarboxylic acid anhydride is used, for example, as an epoxy resin-curing agent, the balance of the composition of the resin composition is stabilized, and a resin molded article having excellent heat resistance, transparency, thermal yellowing resistance, surface hardness, solvent resistance, flexibility, and adhesiveness is thus provided.
