Abstract

The invention relates to a method for producing injection-molded cards with at least one decorative layer (2, 6) which is already applied to a foil (1, 7) or an inlay before injection molding. To protect the inks used for the decoration from thermal action and/or excessive pressures and/or high mechanical stress during injection molding, the decorative layer (2, 6) is covered according to the invention with a protective layer (3, 5) before the foil (1, 7) provided with the decoration or an inlay provided with a decoration is inserted into the injection mold.
