    摘要: Multilayer pearlescent pigments based on platelet-shaped transparent substrates with an optically active coating, where the optically active coating includes at least a) a nonabsorbing high-index layer A having a refractive index n≧1.8, b) a low-index layer B having a refractive index n 150 nm, c) an absorbing high-index layer C having a refractive index n≧1.8 and also, d) optionally an outer protective layer D, wherein the multilayer pearlescent pigments have a cumulative frequency distribution of the volume-averaged size distribution function, with the indices D10, D50, D90 and a span ΔD of 0.7-1.4, the span ΔD being calculated in accordance with the formula ΔD=(D90−D10)/D50. The disclosure further relates to a method for producing these multilayer pigments, and to their use.
