Abstract
A photosensitive material useful for the production of lithographic printing plates, which contains (a) a support suitable for lithographic printing plates, (b) a hydrophilic layer which contains a crosslinkable organic polymer or is a layer formed by crosslinking such a polymer, (c) a photopolymerizable layer and (d) a transparent cover film, the adhesion of the photopolymerizable layer (c) to the hydrophilic layer (b) and/or to the cover film (d) being changed by exposure. The material permits the production of lithographic printing plates having high printing performance without the use of liquid processing agents.
