Document Type and Number:
Japanese Patent JP4466794
Kind Code:
B2
Abstract:
Provided are a photosensitive resin composition which is soluble in an alkaline aqueous solution and which has a good propagation loss in a visible light wavelength region, a photosensitive resin cured matter, a photosensitive resin film, a photosensitive resin film cured matter and an optical waveguide obtained by using the same. Provided are, to be specific, a photosensitive resin composition comprising (A) a vinyl polymer having at least one chain-polymerizable functional group in a molecule, (B) a polymerizable compound and (C) a polymerization initiator, wherein the component (C) is at least one selected from the group consisting of 2-[2-oxo-2-phenylacetoxyethoxy]ethyl oxyphenylacetate, 2-(2-hydroxyethoxy)ethyl oxyphenylacetate and oligo{2-hyroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]}propanone, a photosensitive resin cured matter, a photosensitive resin film, a photosensitive resin film cured matter and an optical waveguide obtained by using the same.
