Abstract
The toner image receiver sheet of the invention, which is useful for digital offset printing, comprises a resin-coated paper substrate on which is disposed an image-receiving layer comprising an imino-functionalized polymer and a polyurethane. In a process for making the receiver sheet, a composition, preferably an aqueous solution containing the imino-functionalized polymer and polyurethane, is applied to a resin-coated surface of a paper substrate, thereby forming an image-receiving layer on the substrate. The image-receiving layer provides the receiver sheet of the invention with a glossy, non-tacky surface having excellent toner transfer and adhesion characteristics.
