Process for selective transfer of metallic foils to xerographic images
First Claim
1. A selective transfer process comprising the steps of:
- providing a sheet comprising toner xerographic images and a metal transfer sheet comprising, in successive layers, a carrier, a metallic film and an adhesive;
placing the sheet comprising toner xerographic images in face-to-face contact with the foil transfer sheet to form a sandwich with the toner xerographic images on the inside;
applying heat and pressure to the sandwich to cause the toner xerograhic image to become tacky and the metallic film to selectively adhere to the images, resulting in a decorated sheet; and
stripping the foil transfer sheet away from the decorated sheet.

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.

17. A selective transfer process comprising the steps of:
-
providing a metal transfer sheet comprising, in layers, a carrier film, a release coat, a polymer film, a metallic film and an adhesive; providing a receiving substrate comprising a toner xerographic image; placing the receiving substrate in face-to-face contact with the foil transfer sheet; while the receiving substrate and the foil transfer sheet are in face-to-face contact, applying heat and pressure to at least one of the receiving substrate and metal transfer sheet to cause the toner xerographic image to become tacky and cause the metal film to adhere to the toner xerographic image, and to thereby cause the formation of a decorated receiving substrate; and stripping away the metal transfer sheet from the decorated receiving substrate. - View Dependent Claims (18, 19, 20)
