Photocurable composition and a method of preparing same

摘要

A photocurable composition and a method of preparing the composition are disclosed. The composition includes (a) a polyester having a photopolymerizable group in its side chains, obtained by a ring-opening alternating copolymerization of a glycidyl ester of a photopolymerizable alpha , beta -unsaturated carboxylic acid and a carboxylic acid anhydride, and (b) a photopolymerization initiator. The composition may also include a photopolymerizable monomer.
