Abstract

The present invention relates to pigment granules which are distinguished by the fact that they are based on a support material, where the support material is coated with one or more flake-form effect pigments by means of an adhesion promoter. The pigment granules according to the invention are preferably used for the pigmentation of application media, in particular paints, plasters, lacquers, powder coatings and plastics, and in particular as scatter and effect granules, for example for the decoration of wallcoverings.
