Resin composition for production of clad layer, resin film for production of clad layer utilizing the resin composition, and optical waveguide and optical module each utilizing the resin composition or the resin film

Abstract

The present invention provides a resin composition and film for forming a cladding layer of an optical waveguide, which composition contains (A) a (meth)acrylic polymer having a weight average molecular weight more than 100,000, (B) a urethane (meth)acrylate, and (D) a radical polymerization initiator; and an optical waveguide and an optical module produced by use of the composition or film. There can be provided a resin composition for forming a cladding layer and a resin film for forming a cladding layer, which exhibit excellent bending durability and twisting durability, and an optical waveguide and an optical module each produced therefrom.
