ABSTRACT:
A security laminate comprising a protective layer having first and second surfaces, an embossing layer bonded to at least a portion of the second surface of the protective layer, a reflective layer bonded to at least a portion of the embossed layer/protective layer composite, an adhesion enhancing layer bonded to a portion of the reflective layer/embossed layer/protective layer composite, an adhesive bonded to at least a portion of the adhesion enhancing layer/reflective layer/embossed layer/protective layer composite wherein the bond between the reflective layer and the adhesion enhancing layer and the bond between the adhesion enhancing layer and the adhesive are each more tenacious than the bond between the reflective layer and the embossed layer and further wherein the bond between the adhesive and the adhesion enhancing layer is more tenacious than the bond between the adhesive and the reflective layer.
