ABSTRACT:
A novel adhesive web or sheet having a carrier backing and an adhesive layer which can be cut with intricate graphic patterns and peeled to leave a reverse image of the desired graphic, as an adhesive on the carrier backing. The adhesive pattern is then transferred to the display or framing substrate, by the application of relatively low heat and pressure. After transfer, the adhesive pattern is right-reading, and serves as the bonding foundation for the ultimate graphic. A graphic sheet having a decorative upper surface, is placed with its lower surface on the adhesive pattern. Relatively low levels of heat and pressure are applied through the top, or decorative surface, thereby attaching the lower surface of the graphic sheet to the adhesive pattern, but not to the remainder of the framing substrate. After cooling, the graphic sheet is peeled away, leaving behind only that portion which bonded to the adhesive pattern. Thus, the observer sees the desired decorative graphic pattern with a raised surface consisting of a portion of the graphic sheet. Preferably, the carrier backing of the adhesive sheet is a transparent plastic, such as 500-700 gauge polyester film, on which a solution coated layer of adhesive including colorant has been applied. Preferably, the coated adhesive layer is a water-based dispersion of ethylene acrylic acid and urethane.
