Abstract
A multi layered card embodying the invention includes an outer layer of an amorphous laser reactive copolymer material which is embossed with a selected pattern at a selected temperature which is above the glass transition temperature, Tg, of the copolymer and below its melting temperature, Tm. So embossed, the selected pattern is set in the copolymer layer, and its external shape cannot be changed from the embossed form to which it was set at the selected temperature, without destroying the selected pattern. The outer layer may be laminated with the other layers of the card and laser engraved before or after lamination.
