RESIN COMPOSITION FOR OPTICAL MATERIAL, RESIN FILM FOR OPTICAL MATERIAL, AND OPTICAL WAVEGUIDE USING THEM

摘要

Disclosed is a resin composition for optical material, which contains a carboxylic acid-modified phenoxy resin (A), a polymerizable compound (B) and a polymerization initiator (C). Also disclosed are a resin film for optical material obtained from such a resin composition, and an optical waveguide having a core portion and/or a cladding layer, each formed by using the resin composition and/or the resin film. The resin composition for optical material is excellent in heat resistance and transparency, while being soluble in an aqueous alkaline solution.
