a cladding layer-forming resin film for forming a cladding layer and a resin composition using the same, an optical module and an optical waveguide using the same

摘要

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.
