Abstract:
A card-shaped data carrier comprising:a support frame, said support frame having two opposed sides; a cover layer disposed over a first side of said support frame, said cover layer having an inner side that is completely bonded to the first side of said support frame over which said cover layer is disposed and an outer side opposite the inner side; a thermoreversible film disposed over the outer side of said cover layer, said thermoreversible film comprising: a carrier film formed of transparent material that has an inner surface bonded directly to said cover layer so that the whole of the inner side of said carrier film abuts said cover layer and an outer surface opposite said cover layer; a thermoreversible color layer bonded directly to the outer surface of said carrier film, wherein said thermoreversible color layer is formed of transparent material on which non-white color images form and fade upon the selective application of heat; and a protective layer disposed over said thermoreversible color layer; and a printed layer applied to the outer side of said cover layer or the inner surface of said carrier film, said printed layer defining at least one visually detectable image; wherein, images are selectively formed on said thermoreversible color layer and by said printed layer so that at least one image formed by said printed layer is visually detectable through a transparent section of said thermoreversible color layer.
