摘要:
A printing ink, preferably ink-jet ink, containing pearlescent pigments and at least one of at least one solvent, at least one radiation-curable component and at least one binder, wherein the pearlescent pigments comprise a substantially transparent platelet-shaped substrate having a density ρS and at least one optically active coating having a density ρM, and the pearlescent pigments have a d90 value for a cumulative frequency distribution of a volume-averaged size distribution function with a range from 3.5 to 15 μm. The invention further relates to a process for producing the printing ink.

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.
