Abstract:
A photosensitive resin composition comprising (A) a polymer carrying carboxyl groups, (B) a compound carrying at least one ethylene-based unsaturated group in the molecule, and (C) a photopolymerization initiator,wherein component (B) contains at least 60 weight % of methacrylate (B1) carrying at least one ethylene-based unsaturated group with respect to the total amount of component (B), and component (C) is present in an amount ranging from 0.01 to 0.20 weight units with respect to 100 weight units of component (A) and component (B), and component (C) contains 2-5 weight units of lophine dimmer (C1) and 0.1 to 2.0 weight units of triphenylphosphine (C2) with respect to 100 weight units of component (A) and component (B), andwherein component (B) carries at least one ethylene-based unsaturated group in the molecule, and contains a vinyl urethane derivative, represented by the following general formula (1) and/or general formula (2): ##STR3##wherein R represents a hydrogen atom or a methyl group and the two R groups can be the same or different; X represents --CH.sub.2 CH.sub.2 O--; Y represents --CH.sub.2 --CH(CH.sub.3)--O--, --CH(CH.sub.3)--CH.sub.2 O--, CH.sub.2 CH.sub.2 CH.sub.2 O--, or CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 O--; Z represents a divalent hydrocarbon group; m, n, p and q are independent of each other and represent an integer of 1-12; ##STR4##wherein R represents a hydrogen atom or a methyl group and the three R groups can be the same or different; X represents --CH.sub.2 CH.sub.2 O--; Y represents --CH.sub.2 --CH(CH.sub.3)--O--, --CH(CH.sub.3)--CH.sub.2 O--, CH.sub.2 CH.sub.2 CH.sub.2 O--, or CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 O--; Z represents a divalent hydrocarbon group; m and p are independent of each other and represent an integer of 1-12.
