Patent ID: 8563223

Claim:
A photosensitive resin composition, comprising: a 20 to 90% by weight of a thermoplastic copolymer containing as a copolymerizing component a monomer containing an α,β-unsaturated carboxyl group, and having an acid equivalent of 100 to 600 and a weight average molecular weight of 5,000 to 500,000, (b) 5 to 75% by weight of an addition polymerizable monomer having at least one terminal ethylenic unsaturated group, (c) 0.01 to 30% by weight of a photopolymerization initiator containing a triaryl imidazolyl dimer, and (d) 0.001 to 10% by weight of a pyrazoline compound represented by the following general formula (I): (wherein, R represents a linear or branched alkyl group having 4 to 12 carbon atoms).
