Abstract
Abstract An image receptor medium including an image reception layer having two major opposing surfaces. The image reception layer comprises an acid- or acid/acrylate-modified ethylene vinyl acetate (EVA) resin. Alternatively, the image receptor medium includes a substrate layer comprising a polymer substrate layer having two major opposing surfaces and an image reception layer on a first major surface of the substrate layer. The image reception layer has an outer surface for receiving images, and comprises an acid- or acid/acrylate-modified ethylene vinyl acetate (EVA) resin. Either embodiment of the image receptor medium may further include an optional prime layer, an optional adhesive layer, and an optional inkjet layer.
