Patent ID: 6989226

Claim:
A photosensitive resin composition for flexographic printing comprising: (A) a hydrophilic copolymer, (B) a thermoplastic elastomer, (C) a photopolymerizable unsaturated monomer, and (D) a photopolymerization initiator, wherein the hydrophilic copolymer (A) is a polymer obtained by copolymerizing at least: (1) 2 to 15 parts by mass of an unsaturated monomer having a carboxyl group, (2) 50 to 80 parts by mass of a conjugated diene monomer, (3) 3 to 20 parts by mass of an aromatic vinyl compound, and (4) 3 to 30 parts by mass of an alkyl (meth)acrylate, per 100 parts by mass of unsaturated monomers for use in the copolymerization, wherein the hydrophilic copolymer (A) has a gel ratio, as measured with toluene, of 80 to 95%.
