Abstract
An improved planographic printing plate comprised of a metal substrate, a sealing layer, an interlayer formed from a monomer or polymer of an organic compound having at least one cationic, quaternary sustituted ammonium group, and a photosensitive layer on the surface of the interlayer. The printing plates are water developable and characterized by cleaner non-imaging areas during printing operations. The method of preparing such planographic printing plates is also described and illustrated.
