Abstract:
The present invention relates to a resin composition for an optical material comprising (A) a carboxylic acid-modified phenoxy resin, (B) a polymerizable compound and (C) a polymerization initiator, a resin film for an optical material comprising the above resin composition and an optical waveguide having a core part and/or a cladding layer formed by using the same. Provided are a resin composition for an optical material which is excellent in a heat resistance and a transparency and which is soluble in an alkaline aqueous solution, a resin film for an optical material comprising the above resin composition and an optical waveguide produced by using the same.
