OPTICAL WAVEGUIDE CLADDING MATERIAL, OPTICAL WAVEGUIDE CLADDING LAYER-FORMING RESIN FILM, AND OPTICAL WAVEGUIDE

摘要

PROBLEM TO BE SOLVED: To provide: an optical waveguide that can be industrially manufactured easily and exhibits small optical transmission loss; an optical waveguide cladding material that can be used to produce such an optical waveguide; and an optical waveguide cladding layer-forming resin film using the optical waveguide cladding material.;SOLUTION: An optical waveguide cladding material contains (A) a polymer having an acidic substituent, (B) a polymerizable compound having two or more ethylenically unsaturated groups, and (C) a polymerization initiator. The (B) polymerizable compound having two or more ethylenically unsaturated groups contains (B1) a polyalkylene glycol di(meth)acrylate having a structural unit derived from polyethylene glycol.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
