Abstract
A carboxyl group-containing epoxy acrylate is prepared by the reaction of an epoxy resin advanced with an aromatic biphenol compound which is reacted with a polycarboxylic acid anhydride in the presence or absence of a catalyst and a polymerization inhibitor at an elevated temperature. The carboxyl group-containing epoxy acrylate is mixed with a photoinitiator to obtain a photoresist formulation.
