Presensitized printing plate and process for the production of dry lithographic printing plates

摘要

A presensitized printing plate for waterless planographic printing with a layer support, a radiation-sensitive layer, an outer, ink-repellent, cross-linked silicone rubber layer and an intermediate layer of amorphous silica is described, which improves the adhesion of the silicone rubber layer to the radiation-sensitive layer. The adhesive layer is physiologically harmless and ensures good anchoring of the silicone rubber layer.
