Patent ID: 8728227

Claim:
Multilayer pearlescent pigments with a silver interference color, based on platelet-shaped transparent substrates with an optically active coating, wherein the optically active coating comprises at least a) a high-index layer A having a refractive index n ≧1.8; b) a low-index layer B having a refractive index n <1.8; c) a high-index layer C having a refractive index n ≧1.8; and also, d) optionally an outer protective layer D and wherein the multilayer pearlescent pigments have the indices D 10 , D 50 , D 90 from the cumulative frequency distribution of the volume-averaged size distribution function, with a span ΔD of 0.7 -1.4, the span ΔD being calculated in accordance with the formula ΔD =(D 90 −D 10 )/D 50 , wherein said multilayer pearlescent pigments have chroma values C * 15 ≦20.
