ABSTRACT:
A presensitized printing plate for waterless lithographic printing is described which is composed of a substrate, a printing ink-repellent crosslinked silicone elastomer coating situated thereon, an intermediate coating of amorphous silicic acid or of an exposed coating of a photosensitive organic halogen compound and a radiation-sensitive coating. The intermediate coating effects a better adhesion of the photosensitive coating to the silicone coating and, consequently, a better resistance to developer and better print run of the plate.
