Zusammenfassung:PURPOSE:To obtain a plate material, containing an adhesive layer having stable ultraviolet light absorbing functions for a long period and having good image reproducibility by forming an adhesive layer containing a pair of polymers comprising a benzophenone-based monomer between a substrate and a photosensitive resin layer. CONSTITUTION:This plate material is obtained by forming an adhesive layer containing a polymer, preferably comprising a benzophenone-based monomer composed of a compound expressed by the formula {X is 0 or ORO [R is a l-10C alkylene (having one or more OH groups)]; Y is H or methyl} and having 3000-200000 weight-average molecular weight between a metallic or a plastic substrate and a photopolymerizable and photosensitive resin layer. Furthermore, the adhesive layer preferably contains the polymer comprising the benzophenone- based monomer in an amount of 1-50 pts.wt. based on 100 pts.wt. binder polymer such as a polyester and a polyvalent isocyanate in an amount of 5-200 pts.wt. based on 100 pts.wt. binder polymer such as the polyester.
