PURPOSE:To obtain a damping water-free photosensitive lithographic printing plate with the vacuum contact with an original-picture film excellent when the picture is exposed, with the time required for vacuum contact reduced and consequently excellent in productivity. CONSTITUTION:A photosensitive resin layer, an ink repelling layer and a cover film are laminated on a substrate to constitute the moistening water-free photosensitive lithographic printing plate. In this case, a resin layer consisting of a film forming polymer binder contg. silica grains having 10-30mum average diameter measured by the Coulter counter method is formed on the surface of the cover film. |
