Patent ID: 8361697

Claim:
A photosensitive resin composition comprising: (a) 20-90 wt % of a thermoplastic copolymer obtained by copolymerization of a copolymerizing component containing at least one compound selected from the group consisting of compounds represented by the following formula (I): (wherein R 1 represents hydrogen atom or methyl group, and R 2 represents a group selected from the group consisting of hydrogen atom, halogen atoms, hydroxyl, C1-12 alkyl, C1-12 alkoxy, carboxyl and haloalkyl groups), and compounds represented by the following formula (II): (wherein R 3 represents hydrogen atom or methyl group, and R 4 represents a group selected from the group consisting of hydrogen atom, halogen atoms, hydroxyl, C1-12 alkyl, C1-12 alkoxy, carboxyl and haloalkyl groups), and having a carboxyl group content of 100-600 acid equivalents and a weight-average molecular weight of 5,000-500,000, (b) 5-75 wt % of an addition polymerizable monomer having at least one terminal ethylenic unsaturated group, (c) 0.01-30 wt % of a photopolymerization initiator containing a triarylimidazolyl dimer, and (d) 0.001-10 wt % of a pyrazoline compound represented by the following formula (III): (wherein R 5 represents a C4-12 straight-chain or branched-chain alkyl group).
