Abstract:
1. A photosensitive resin composition comprising: (A) a binder polymer; (B) a photopolymerizing compound with an ethylenic unsaturated bond; (C) a photopolymerization initiator; and (D) a compound represented by the following general formula (1a), (1b), (1c), or (2), wherein in formula (1a), X in formula (1b), X in formula (1c), X wherein in formulae (3) and (4), at least one of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12 represents C1-20 alkyl and the other represent hydrogen; and in formula (2), X wherein the acid value of component (A) is 45-200 mg KOH/g, and wherein component (A) contains polymerizable monomer with a carboxyl group, (meth)acrylic acid alkyl esters, and styrene or a styrene derivative as a copolymerizing component, component (B) contains a bisphenol A-type (meth)acrylate compound, and component (C) contains a 2,4,5-triarylimidazole dimer, and wherein component (A) contains 0.1 to 30 wt % of the styrene or styrene derivative as a copolymerizing component, with respect to the total amount of component (A), and the photosensitive resin composition is developable in an aqueous alkali solution having a pH in the range of 9 to 11.
