49.5 g of the sulfonic acid group-containing polyurethane was kneaded, in a nitrogen atmosphere at 150° C. using a pressure kneader, with 20 g of a styrene-isoprene block copolymer (Cariflex TR 1107, a product of Shell Chemical Ltd.), 2 g of sodium laurylbenzenesulfonate, 5 g of a polybutadiene diacrylate (BAC-45, a product of Osaka Organic Chemical Ind. Ltd.), 1 g of an aliphatic diacrylate (C-2000, a product of THERTOMER), 2 g of dioctyl fumarate, 2 g of 2,2- dimethoxyphenylacetophenone, 10 g of a maleinized polybutadiene (ME-1000-80, a product of Nippon Petrochemical Co., Ltd.), 7.5 g of N-ethyltoluenesulfonamide and 0.1 g of 2,2-di-t-butyl-p-cresol, thereby forming a uniform transparent photosensitive resin composition.
