An object of the present invention is to provide a photosensitive resin composition which is excellent in the compatibility (dispersibility) of photosensitive resin composition components, developability with aqueous developer solution, water resistance, image reproducibility, print wear characteristics in printing with a water base ink and plate wiping-off resistance in removal of ink adhered to any printing plate. The present invention relates to a photosensitive resin composition comprising a hydrophilic copolymer (A) 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-type 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.
