摘要： PURPOSE:To improve sensitivity and printing resistance by providing a photosen sitive layer consisting of a negative effect diazo resin layer as an intermediate adhesive layer and a polymer which has a maleimide group in the side chain and allows photo-network formation onto a base having a hydrophilic surface. CONSTITUTION:The negative effect diazo resin layer is provided between the base subjected to a hydrophilicity impartation treatment and the photosensitive layer consisting of the polymer which has the maleimide group in the side chain and allows the photo-network formation. The resin layer is then subjected to image exposing by using a light source of ample UV rays and is processed by a processing soln. to remove the unexposed part of the photosensitive layer; finally a gum liquid is applied on the resin layer to form the planographic printing plate. The planographic printing plate having the excellent printing performance while maintaining the excellent sensitivity of the polymer which has the maleimide group in the side chain and allows the photo-network forma tion is obtd. in this way.
