Abstract
An article capable of being hot stamped with desired lettering or designs comprising a plastic laminate and an overlying carrier film with colored matter attached to an appendage portion of the plastic laminate. The back of the laminate has a pressure-sensitive adhesive protected by a removable covering or backing. The method of imprinting and using the article comprises hot stamping the foil and underlying plastic laminate to form the desired lettering or design, removing the foil and appendage portion from the plastic laminate, removing the protective backing to expose the adhesive and to affix the imprinted laminate to a plaque or other item. The process of imprinting on the article includes hot stamping the laminate to deboss it and transfer the coloring matter to the debossed portions, and removing the carrier film. The process for forming the article includes cutting the plastic laminate and carrier film to a desired size and shape, slitting the laminate to form a plate portion and an appendage portion, and securing the carrier film to the appendage portion.
