The card core is printed either on one or two sides. The method is carried out in the following manner: the printed layers of the card core are prepared; the protective layers are prepared; the adhesive layers are applied to the individual protective and/or core layers; the individual card layers are precisely positioned one on top of the other; the card layers are joined together in a lamination press with the aid of pressure and heat. An adhesive system which is cross-linked under the effect of pressure and/or heat, comprising a thermoplastic synthetic component and a cross-linking component, is used in at least one adhesive layer.
