Abstract
The present invention is directed to a method for selectively transferring metallic foil and xerographic images on a receiving substrate such as paper. The method generally comprises providing a transfer sheet (including a metallic film) and a receiving substrate (including xerographic images disposed thereon.) The receiving substrate is placed in face-to-face contact with the transfer sheet to form a sandwich with the xerographic images on the inside. the sandwich is then fed through an apparatus, where heat and pressure are applied, causing the xerographic images to tackify and causing the metal film from the transfer sheet to selectively adhere to the xerographic images.
