Abstract
A water-developable photosensitive resin composition which exhibits a small swelling, small reduction in strength and small dimension change when developed with water and which has an excellent balance of characteristics. Said composition comprises (1) a oarboxyl group-containing diene polymer, (2) a hydrogenated diene block polymer in which at least 80% of the double bonds in the recurring unit consisting of conjugated diene has been hydrogenated, (3) a photopolymerizable ethylenically unsaturated monomer, (4) an amino group-containing compound and (5) a photopolymerization initiator.
