Patent ID: 7022462

Claim:
A photosensitive resin composition comprising (A) a carboxyl group-containing binder polymer which contains styrene or a styrene derivative as a copolymerized constituent, (B) a 2,4,5-triarylimidazole dimer as a photo-polymerization initiator, and (C) a photo-polymerizable compound having in its molecule at least one polymerizable ethylenically unsaturated bond which comprises a compound represented by the general formula (I) wherein R 1 is a hydrogen atom or a methyl group, A is an alkylenoxy group of 2 to 6 carbon atoms, Z 1 is a halogen atom, an alkyl group of 1 to 20 carbon atoms, a cycloalkyl group of 3 to 10 carbon atoms, an aryl group of 6 to 14 carbon atoms, an amino group, an alkylamino group of 1 to 10 carbon atoms, a dialkylamino group of 2 to 20 carbon atoms, a nitro group, a cyano group, a mercapto group, an alkylmercapto group of 1 to 10 carbon atoms, an allyl group, a hydroxyalkyl group of 1 to 20 carbon atoms, a carboxyalkyl group wherein the alkyl group has 1 to 10 carbon atoms, an acyl group having an alkyl group of 1 to 10 carbon atoms, an alkoxy group of 1 to 20 carbon atoms or a group containing an heterocyclic group, m is an integer of 6 to 20, and n is an integer of 0 to 5.
