<P>PROBLEM TO BE SOLVED: To provide a photosensitive resin composition having high sensitivity and excellent flexibility, plating property and heat resistance, and to provide a photosensitive film using the composition. <P>SOLUTION: The photosensitive resin composition comprises (A) a polymerizable prepolymer having a carboxyl group and an ethylenically unsaturated group, (B) a photopolymerization initiator generating a free radical by active rays, (C) a black pigment or a dispersion of a black pigment, (D) a thermoplastic polymer having a carboxyl group, (E) an urethane unsaturated organooligomer, and (F) a photopolymerizable compound. For the photopolymerization initiator as the component (B) generating a free radical by active rays, a combination of two or more in the following compounds is used: (B)-(1) 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butanone-1; (B)-(2) 2,2-dimethoxy-1,2-diphenylethan-1-one; and (B)-(3) ethanone, 1-[9-ethyl-6-(2-methylbenzoyl)-9H-carbazol-3-yl]-,1-(0-acetyloxime). <P>COPYRIGHT: (C)2013,JPO&INPIT |
