Abstract
Photopolymeric printing plates are presented wherein and electrochemically etched and anodized, silicated aluminum substrate has a single photosensitive coating thereon composed of a photopolymerizable combination which includes a photopolymerizable pigment dispersion, a photosensitive lithographic diazonium resin, multifunctional acrylate oligomer, multifunctional acrylate monomer, photopolymerizable binder and photoinitiator to yield a non-tacky, mar resistant, easily developed durable plate. In a preferred embodiment, an additional aqueous, non-photosensitive overcoat is applied over the initial coating to retard oxygen inhibition.
