PHOTOSENSITIVE RESIN COMPOSITION, CURED PHOTOSENSITIVE RESIN PRODUCT, PHOTOSENSITIVE RESIN FILM, CURED PHOTOSENSITIVE RESIN FILM PRODUCT, AND OPTICAL WAVEGUIDE PRODUCED BY USING THOSE PRODUCTS

摘要

Disclosed are: a photosensitive resin composition which is soluble in an aqueous alkaline solution and which has good transmission loss in the visible light range; a cured photosensitive resin product; a photosensitive resin film; a cured photosensitive resin film product; and an optical waveguide produced by using those products. Specifically disclosed are: a photosensitive resin composition which comprises (A) a vinyl polymer having at least one chain-polymerizable functional group per molecule, (B) a polymerizable compound and (C) a polymerization initiator, wherein the component (C) is at least one member selected from the group consisting of oxyphenylacetic acid 2-[oxo-2-phenylacetoxyethoxy]ethyl ester, oxyphenylacetic acid 2-(2-hydroxyethoxy)ethyl ester and oligo[2-hydroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]]- propanone; a cured photosensitive resin product; a photosensitive resin film; a cured photosensitive resin film product; and an optical waveguide produced by using those products.
