More Information
Summary:The invention relates to pearlescent pigments, comprising a substantially transparent, platelet-shaped substrate, having a density [delta]s, and at least one optically effective coating having a density [delta]M, wherein the substrate has a mean size d50 of n 3 to 8 [mu]m, and a mean height hs of 40 to 110 nm. The invention further relates to a method for the production of the pearlescent pigments, and the use thereof.
