Patent ID: 6870678

Claim:
A surface pattern with a visually visible mosaic comprising first surface portions and second surface portions embedded in a laminate of at least a transparent cover layer and a protective layer, wherein the first surface portions are in the form of transparent windows and the second surface portions which are at least partially covered with a reflection layer are in the form of mirror surfaces, optical-diffraction surfaces with microscopic relief structures and surface portions which scatter incident light beams, wherein for a predetermined limit wavelength (λ G ) of the violet part of the visible spectrum at least in one of the optical-diffraction surfaces in an area defined by co-ordinates x and y, the microscopic relief structure is in the form of a zero order microstructure (ZOM-structure) and is of a spatial frequency (f) such that the product (P) of the limit wavelength (λ G ) and the spatial frequency (f) is greater than or equal to 1, in the other optical-diffraction surfaces the spatial frequencies (f) of the other microscopic relief structures satisfy the condition that the product (P) is less than 1, and in each location defined by the co-ordinates (x, y) in the area a profile height (h) of the ZOM-structure is optically effective, wherein a grating structure (G{x, y}) of the ZOM-structure is modulated by means of a low-frequency envelope curve surface (H{x, y}) at a frequency (F), wherein the frequency (F) is less than five periods per millimeter.
