titleOfInvention | Radiation-sensitive resin composition for optical waveguides, optical waveguide, and method for manufacturing optical waveguide |
abstract | A radiation-sensitive resin composition for optical waveguides having high dimensional accuracy, good transmission characteristics, and excellent bending resistance is provided. The composition comprises: (A) a poly(meth)acrylate having a repeating unit represented by the following general formula (1)n n(in the formula, R 1 is a hydrogen atom or a methyl group, R 3 is a (meth)acryloyl group, X is a bivalent organic group); (B) an urethane (meth)acrylate compound which is a reaction product of a polyester polyol compound, a polyisocyanate compound, and a (meth) acrylate having a hydroxyl group; (C) a compound having at least one ethylenically unsaturated group and having a boiling point of 130 degree C or higher under 0.1 MPa other than components (A) and (B); and (D) a photo-radical polymerization initiator. The composition was used as the material for the lower clad layer 12 of the optical waveguide 24, and the like. |
