Title:
RESIN COMPOSITION FOR OPTICAL MATERIAL, RESIN FILM FOR OPTICAL MATERIAL AND OPTICAL WAVEGUIDE USING SAME
Document Type and Number:
WIPO Patent Application WO/2006/038691
Kind Code:
A1
Abstract:
Disclosed is a resin composition for optical materials which contains a base polymer (A), a photopolymerizable compound (B) and a photopolymerization initiator (C). Also disclosed is a resin film for optical materials which is made of such a resin composition for optical materials. Specifically disclosed is a resin composition for optical materials which has high transparency and high heat resistance, while enabling formation of a thick film with high precision. This resin composition is particularly useful for a resin film which is used for forming optical waveguides. Also specifically disclosed are a resin film for optical materials using such a resin composition and an optical waveguide using such a resin film.
