Claim:
Pigment granules comprising a support material which is coated with one or more flake-form effect pigments by means of an adhesion promoter, wherein the one or more flake-form effect pigments comprise a flake-form support coated with one or more layers selected from the group consisting of transparent layers, semitransparent layers, opaque layers, and a combination thereof, wherein the support material is a polymer particle, a solid glass bead, a hollow glass bead, or mixtures thereof, and have particle sizes of 0.05-50 mm, and wherein the adhesion promoter comprises an emulsion selected from the group consisting of an ethylene-acrylic acid (EAA) emulsion, a low-chlorinated polypropylene emulsion, a non-chlorinated polypropylene emulsion, and a wax emulsion, wherein the granules comprise: 0.1-50% by weight of the one or more effect pigments, 50-99.5% by weight of the support material, 0.1-10% by weight of the adhesion promoter, and 0.05-10% by weight of one or more additives, based on the pigment granules, where the total proportion of all components in the pigment granules is 100% by weight.
