COPOLYMER, MONOMER COMPOSITION, RESIN SOLUTION, AND RESIN FILM

摘要

This copolymer is characterized by containing a repeating unit derived from phenyl phenyl (meth)acrylate, a repeating unit derived from an unsaturated compound containing a hydroxyphenyl group, and a repeating unit derived from an unsaturated compound containing an epoxy group. This copolymer exhibits both superb transparency and a high refractive index. A resin film formed from this copolymer is suitable for use, for example, in the formation of: a protective film or interlayer insulating film for an electronic component such as a liquid-crystal display element, an integrated-circuit element, or a solid-state imaging element; a microlens or microlens array; or an optical waveguide.
