• the structure obtained by shaping has recesses and/or raised portions arranged in groups, wherein the recesses and/or raised portions are shaped as cylinders, prisms, truncated cones, truncated pyramids or of a substantially rectangular or trapezoidal cross-section and as top surfaces have element surfaces, wherein the dimensions of the element surfaces are in the range of between 250 nm and 300 μm,
• a group surface occupied by the group is composed of the element surfaces and residual surfaces and the group surface is of a width of between 30 μm and 300 μm,
• the element surfaces of a group are in a parallel plane displaced with respect to a shaping surface and the residual surfaces are in the plane of the shaping surface,
• the groups are separated by regions of a background area, which are in the plane of the shaping surface,
• a protective layer covers a structured side of the base foil having a reflection layer in such a way that the recesses of the structure in the base foil are filled and the reflection layer is enclosed between the base foil and the protective layer and
• the protective layer or an adhesive layer arranged on the side of the protective layer, which is remote from the reflection layer, is adapted for connection to a substrate;
• and characterized in that the decorative foil covers a part of the substrate and is connected thereto by means of the adhesive layer.
