Abstract
A photosensitive resin base printing material in the form of laminate comprising, in successive order, a support, a photosensitive resin layer, a slip layer of a high molecular substance which is soluble or swellable in a developer, an optional releasing layer and a sheet or film form of protective layer, which is characterized in that a dyestuff is included in an amount of 0.01 to 20% by weight of the high molecular weight substances in said slip layer. The present printing material is specifically excellent in resolution and far improved as compared with heretofore proposed printing materials in respect to both handling and visual inspection properties.
