Abstract
Abstract Thermal dye transfer receiving elements are disclosed comprising a base having thereon a dye image-receiving layer, the base comprising a composite film laminated to a support, the dye image-receiving layer being on the composite film side of the base. The composite film comprises a microvoided thermoplastic core layer and at least one substantially void-free thermoplastic surface (skin) layer, and wherein there is a subbing layer between the thermoplastic surface layer and the dye image-receiving layer, the subbing layer comprising gelatin and titanium dioxide.
