Abstract
This invention relates to a photopolymerizable resin composition containing resin component (A) composed of a resin and/or a resin-forming ingredient and a photopolymerization initiator (B) wherein the component (A) comprises an addition-polymerizable compound (A1) having at least two ethylenically unsaturated groups and the photopolymerization initiator (B) comprises a diaminobenzophenone compound (B1), an N-phenylglycine compound (B2), and at least one kind of compound selected from a group of a 3,3′,4,4′-tetra(alkylperoxycarbonyl)benzophenone (B3), 2-methyl-1-[4-(thiomethyl)phenyl]- 2-morpholinopropan-1-one (B4), and a 1,3,5-triazine derivative (B5) containing at least one trihalomethyl group as substituent. A photopolymerizable resin composition of this invention excels in resolution, adhesion of patterns, development latitude, and curing on the surface and inside and can be used advantageously in insulating films, colored films, inks for color filters, resists for semiconductors, and insulating spacers for touch panels.
