<P>PROBLEM TO BE SOLVED: To provide a photosensitive resin composition capable of making both reciprocal performances of water developing property for shortening the plate making time and of printing wear compatible with each other while a water-based ink is deposited on the plate face of the printing plate. <P>SOLUTION: The photosensitive resin composition for flexographic printing contains: (A) a hydrophilic polymer; (B) a hydrophobic polymer; (C) a plasticizer; (D) a photopolymerizable unsaturated monomer; and (E) a photopolymerization initiator. The plasticizer (C) contains a butadiene polymer, an isoprene polymer or a butadiene/isoprene block copolymer having (1) a molecular weight of 10,000 to 60,000 and (2) ≤25% of 1, 2-vinyl group content. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
