Credit card and method of making the same
An improved credit card having a clear, unbroken metallized surface with printed graphics thereon which is scratch resistant and a method of making the same are disclosed. The method involves heat transferring a metallized foil to a first surface of a plastic substrate, silk-screen printing over the metallized foil with ultraviolet curable ink, drying the ink with ultraviolet light and overlaminating the printed foil with a clear polyester film coated with a heat-activated adhesive or coating it with an ultraviolet curable varnish which is cured by applying ultraviolet light to the coating. The plastic substrate is in the form of a large sheet from which a plurality of cards are die cut after the printing and application of the transparent film. A magnetic tape is then applied to the back of each card.
