摘要 |
The security strip (7) comprises a transfer film, preferably a hot embossing film, with at least two plastic or lacquer layers, between which is at least one optically active layer and/or structure whose optical effect varies according to the angle at which it is looked at or illuminated. The optically active layer and/or structure is located only in at least two defined surface regions separated from each other by a distance. Outside these regions the strip is transparent and/or its appearance does not change if the angle at which it is looked at or illuminated is varied and/or it is adapted to the appearance of the surface (2) of the substrate to which it is adhered. An independent claim is also included for a valuable document with the security strip. |
