Zusammenfassung:	PURPOSE: To enhance photosensitivity by introducing a group capabel of photooxidation in the presence of a dye photo-reducible at the time of exposure in a specified mixture of acrylate or alkylacrylate. CONSTITUTION: A photoresist having high printing ability durable for a long time and high in resistance to treatment with a solution in a cured state is formed by using a composition of a polymer binder, the polyol acrylate or alkylacrylate having one or more groups capabel of photooxidation in the presence of the photoreducible dye at the time of exposure and one or more urethane groups, and the photoreducible dye as a photopolymerization initiator, thus permitting high photosensitivity to be obtained.
