Pigments granules

摘要

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.

主权项

1. Pigment granules comprising at least one support material which is coated with at least one flake-form effect pigment by means of at least one adhesion promoter, wherein:
a) the support material comprises solid polymer beads, hollow polymer beads, solid glass beads or hollow glass beads which have a particle size D50 of 15 to 299 μm, and the proportion of flake-form effect pigment in the pigment granule is 40-90% by weight, or b) the support material comprises solid glass beads or hollow glass beads which have a particle size D50 of 3 to 1000 μm, and the proportion of flake-form effect pigment in the pigment granule is from more than 50% to 75% by weight; and c) the at least one adhesion promoter comprises 1 10% by weight of the granule and is selected from the group consisting of: ethylene-acrylic acid emulsions (EAA), acrylate dispersions, polyurethane dispersions and acrylate-polyurethane copolymer dispersions.
