Abstract:
A photosensitive resin composition developable with a diluted alkali aqueous solution comprising:(A) a water-soluble photosensitive resin selected from the group consisting of a first resin obtained by introducing a styryl pyridinium group into a polyvinyl alcohol polymer, a second resin obtained by introducing a styryl quinolinium group into a polyvinyl alcohol polymer, and a third resin obtained by adding N-alkylol (meth) acrylamide to a polyvinyl alcohol polymer; (B) a photosensitive prepolymer having a carboxyl group and at least two photopolymerizable ethylenically unsaturated groups in the molecule; (C) a photopylymerization initiator; and (D) water, wherein a compounding amount of said water-soluble photosensitive resin (A) is in a range of 0.1 to 50 weight % with respect to the total amount of all components of said photosensitive resin composition excluding the amount of water, and a compounding amount of said photosensitive polymer (B) is in a range of 30 weight % or more with respect to the total amount of all components of said photosensitive resin composition excluding the amount of water.
