Abstract:
A card laminate is produced from a centrally disposed foil laminate (1) consisting of an interior layer (2) with a metal layer (3) and with two exterior transparent plastic layers (4a, 4b), and two exterior plastic films (5a, 5b) of which at least the plastic film (5a) overlying the metal layer (3) is transparent and carries a print (6a). If the print (6a) is on the exterior, a transparent cover layer (7a) is furthermore provided. Materials and layer thicknesses are preferably selected symmetrically to the interior, metallized layer (2, 3) in order to reduce warping effects.
