Abstract
A presensitized printing plate suitable for waterless planographic printing is disclosed, which comprises a layer support, a radiation-sensitive layer, an outer, ink-repellent, cross-linked silicone elastomer layer, and an intermediate layer of amorphous silicic acid, by which the adhesion of the silicone elastomer layer to the radiation-sensitive layer is improved. The adhesive layer is physiologically safe and effects a good anchoring of the silicone elastomer layer. The process of making and using the presensitized printing plate are also disclosed.
