A decorative foil is in the form of a layer composite structure (1) and comprises at least a transparent base foil (2), a transparent cover layer (4) and a transparent dielectric layer (3) arranged between the base foil (2) and the cover layer (4). When the decorative foil serves as a lamination foil for a substrate (5) the material of the cover layer (4) is an adhesive. A reflective metallic layer (6) is arranged at least in surface portions between the dielectric layer (3) and the cover layer (4) and optionally a metal film (11) is also arranged on the side of the dielectric layer (3) facing the base foil (2). General items of information shown by the decorative foil are produced by means of modulation of the thickness (s) of the dielectric layer (3). Transparent locations (7) form individual items of information, wherein the transparent locations (7) are produced with a laser beam (19) by perforating the metal layer (6; 11). Besides being used as a lamination foil the decorative foil can also be used as a packaging foil.
A decorative foil with a layer composite structure comprising a transparent base foil, a transparent cover layer and a transparent dielectric layer arranged between the base foil and the cover layer, wherein a metallic layer is arranged between the dielectric layer and the cover layer in surface portions, wherein a transparent metal film is arranged between the dielectric layer and the base foil in regions corresponding to the surface portions of the metallic layer, and wherein a first interface in which the refractive index abruptly changes is provided between the dielectric layer and the base foil.
