Claim:
1. A photosensitive resin composition for CTP flexographic printing original plate containing at least a hydrophobic polymer obtained from water-dispersible latex (A), a hydrophilic polymer (B), a photopolymerizable unsaturated compound (C) a photopolymerization initiator (D), and a rubber (E) for imparting rubber elasticity to the photosensitive resin composition, wherein the content of the rubber (E) is 1 to 7% by mass of the photosensitive resin composition, characterized in that, the photopolymerizable unsaturated compound (C) comprises a photopolymerizable oligomer containing no hydroxyl group (C-1), a hydroxyl group-containing photopolymerizable monomer having a weight-average molecular weight of 200 to 1500 and having a pentaerythritol skeleton, a dipentaerythritol skeleton or a glycerol skeleton (C-2) and, a photopolymerizable monomer containing no hydroxyl group (C-3), wherein the content of the hydroxyl group-containing photopolymerizable monomer (C-2) is 1 to 20% by mass of the photosensitive resin composition.
