Abstract (en)
[origin: WO2007141040A1] The invention relates to a substrate (1, 8, 9) with a sequence of layers (2, 7) thereon to produce a changing color impression depending on the viewing angle, with the sequence of layers (2, 7) having a reflecting layer (3) that reflects electromagnetic waves, a spacing layer (4) on the reflecting layer (3) that is transparent to electromagnetic waves, and an absorbing layer (5) of metallic clusters on the spacing layer (4), wherein the reflecting layer (3) is partially transparent to electromagnetic waves.
