Patent ID: 8728226

Claim:
Multilayer pearlescent pigments, comprising platelet-shaped transparent substrates provided with an optically active coating, wherein the optically active coating comprises at least (a) an absorbing 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≧1.8and also d) optionally at least one outer protective layer D and in that the multilayer pearlescent pigments have a cumulative frequency distribution of a volume-averaged size distribution function, with the indices D 10 , D 50 , D 90 and a span ΔD in a range from 0.7-1.4, the span ΔD being calculated in accordance with formula (I) Δ D =( D 90 −D 10 )/ D 50 , (I), wherein said multilayer pearlescent pigments have chroma values C * 15 >20.
