PROBLEM TO BE SOLVED: To provide neutral, covering, metallic, discreetly colored or black, mirror-like metallic pigments with a light/dark flop that is very high until a point in time, which preferably is easy to produce.SOLUTION: A platelet-shaped PVD metallic effect pigment having first and second outer faces, the platelet-shaped PVD metallic effect pigment having at least one PVD layer, the at least one PVD layer including elemental metal with clusters of elemental metal and metal oxide. The amounts of elemental metal in the first outer face and in the second outer face of the PVD metallic effect pigment are different from one another and they differ by at least 10 atom%. The disclosure further relates to a method for producing the platelet-shaped PVD metallic effect pigments in a vacuum chamber by means of reactive physical vapor deposition (PVD).SELECTED DRAWING: None |
