    摘要: The invention relates to a non-dusting, homogeneous pigment preparation which is distinguished by the fact that it comprises at least 40% by weight of one or more effect pigments and 0.5-59.5% by weight of a modified colophony resin, based on the pigment preparation, and the use thereof, in particular for the production of dry preparations. The pigment preparation according to the invention and the dry preparations produced therefrom are particularly suitable for the pigmenting of paints, coatings, powder coatings, printing inks and plastics.
