Abstract: A co-mingled polyurethane-polyvinyl ester composition can be used as a coating, which has good scratch, mar and solvent resistance. The coating is derived from a waterborne polyurethane solution containing free radically polymerizable monomers such as acrylate, ultraviolet light initiators, and optionally urethane crosslinking agents. A process for forming the co-mingled polyurethane-polyvinyl ester composition comprises drying the waterborne polyurethane containing the polymerizable monomers therein and radiation polymerizing, as by ultraviolet light, the free radically polymerizable monomers on a substrate such as a plastic sheet to form a laminate. Subsequently, the laminate can be utilized to form a coating on a product as by thermoforming, where if urethane crosslinking agents are utilized, the polyurethane will be crosslinked.
