Abstract: The present invention is directed to a composite laminated article including a resin coated base plate and a layer of ordered photocurable composition on said resin coated plate and when the liquid photocurable composition is cured forms a polymeric printing plate. The article includes a sheet of aluminum-containing metal having a coating of a cured mixture of a specific vinyl resin and an epoxy resin and preferably a small amount of carbon black and silica and a top coat or layer of photocured ordered polyurethane containing acrylate or methacrylate radicals.

Abstract: A liquid ethylenically unsaturated polurethane composition having no free NCO and a viscosity of 2,000 to 10,000 centipoises at 24.degree. C. dispersible in dilute caustic and capable of being polymerized by actinic light to yield a solid having a Shore A hardness of at least 30. Said composition may contain a diluent and a photosensitizing agent to adjust the viscosity and making the composition more readily utilizable for making printing plates.
