A water-developable photosensitive resin composition which comprises: (1) a particulate copolymer comprising, as recurring units in the copolymer, (a) 10 to 95 mole % of an aliphatic conjugated diene unit, (b) 0.1 to 30 mole % of a monomer unit having at least one polymerizable unsaturated group and at least one functional group selected from the group consisting of carboxyl group, amino group, hydroxyl group, epoxy group, sulfonic acid group and phosphoric acid group, and (c) 0.1 to 20 mole % of a monomer unit having at least two polymerizable unsaturated groups; (2) at least one copolymer selected from the group consisting of (i) a block-like copolymer composed of two or more polymeric segments having a sulfonic acid group in at least one of the polymeric segments, (ii) a block-like copolymer composed of two or more polymeric segments having a polyurethane segment in at least one of the polymeric segments, and (iii) a copolymer of ethylene and an alpha -olefin having 3 to 20 carbon atoms; (3) a photopolymerizable unsaturated compound; and (4) a photopolymerization initiator.
