  • Patent number: 8883879
    Abstract: Pigment granules including a support material which is coated with one or more flake-form effect pigments by means of an adhesion promoter. The effect pigments may be, for example, pearlescent pigments, interference pigments, metal-effect pigments, multilayered pigments having one or more transparent, semi-transparent or opaque layers, goniochromatic pigments, holographic pigments, coated BiOCL flakes, uncoated BiOCl flakes, and LCP pigments, and mixtures thereof. A process for the production of pigment granules includes mixing one or more flake-form effect pigments, a support material, at least one adhesion promoter, and optionally one or more additives simultaneously or successively with one another. The pigment granules may be used for the pigmenting of application media, in particular paints, plasters, coatings, powder coatings, plastics, and in particular as scatter and effect granules, for example for the decoration of wallcoverings.
