PURPOSE:To obtain a photosensitive resin original plate with superior printing resistance and suitability to high-speed printing by incorporating basic polyamide resin contg. nitrogen, a monomer having a polymerizable unsatd. bond, and a specified modifier having one or two terminal carboxyl groups into a photosensitive resin layer. CONSTITUTION:To 100pts.wt. basic polyamide resin (A) contg. nitrogen are added 5-200pts.wt. monomer (B) having a polymerizable unsatd. bond such as acrylamide or methyl acrylate and 3-50pts.wt. compound (C) represented by formula I or II (where each of R<1> and R<2> is 1-10C alkylene or phenylene, and (n) is 1-20) such as polyethylene glycol monosuccinate. They are mixed, and the mixture is blended with other necessary additives. The resulting photosensitive resin composition is coated on a substrate with an adhesive layer and an antihalation layer in-between, and by drying the coated composition, a photosensitive resin layer is formed to obtain the desired photosensitive resin original plate. |
