OPTICAL WAVEGUIDE PHOTOSENSITIVE RESIN COMPOSITION, PHOTOCURABLE FILM FOR FORMING OPTICAL WAVEGUIDE CORE LAYER, OPTICAL WAVEGUIDE USING SAME, AND MIXED FLEXIBLE PRINTED CIRCUIT BOARD FOR OPTICAL/ELECTRICAL TRANSMISSION

摘要

Provided is an optical waveguide photosensitive resin composition containing a photocurable resin and a photopolymerization initiator, in which the photopolymerization initiator is a specific photoacid generator represented by the general formula (1). Accordingly, when a core layer is formed by using the optical waveguide photosensitive resin composition as a material for forming an optical waveguide, especially a core layer-forming material, excellent high transparency (low loss effect) is obtained.;;In the formula (1), R1 and R2 each represent hydrogen or an alkyl group having 1 to 15 carbon atoms, and may be identical to or different from each other.
