Abstract: The present invention relates to inorganic spherical pigments which are based on spherical particles having a particle diameter of 0.1-100 ?m and are coated on the surface with agglomerates selected from the group ZrO2, ZnO, Al2O3, TiO2, Fe2O3, Fe3O4, FeOOH and BaSO4 or mixtures thereof, and are optionally coated with a further layer (2nd layer) comprising a metal oxide, lake or Berlin Blue, and to the use thereof in paints, coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, in cosmetic formulations, as tracer, as filler and for the preparation of pigment preparations and dry preparations.

Abstract: The present invention relates to a method for the characterisation of pigments and fillers in which the luminance of a pigmented transparent medium is determined against a dark background. This measurement method is particularly suitable for determining the optical properties of cosmetic fillers.
