Pigmentgranulat, enthaltend 40-65 Gew.-% Pigment und mindestens 10 Gew.-% einer Verbindung der allgemeinen Formel I CH3-(CH2)n-CH2-O-[(CH2)p-O]m-H, mit n = 8-18, p = 1-4 und m = 35-100, wobei das Gewichtsverhältnis der Verbindung der allgemeinen Formdes Pigmentes in m2/g multipliziert mit 0,0021 g/m2 ist und die massengewichtete mittlere Korngröße des Pigmentgranulates < 20 µm beträgt. Das Pigmentgranulat kann hergestellt werden, indem man das Pigment und die Verbindung der Formel I in einem Lösungsmittel dispergiert und anschließend die erhaltene Dispersion trocknet. Sie können zur Einfärbung und/oder Antistischausrüstung in wasserbasierenden Farben- und Lacksystemen, Dispersionsfarben, Druckfarben, Tintensystemen und Beschichtungssystemen verwendet werden. The invention relates to a pigment granulate which contains 40 to 65% by weight of pigment and at least 10% by weight of a compound of general formula (I) CH3-(CH2)n-CH2-O-[(CH2)p-O]m-H, wherein n=8-18, p=1-4 and m=35-100, the weight ratio of the compound of general formula I to the pigment being the STSA surface area of the pigment in m2/g multiplied by 0.0021 g/m2 and the mass-weighted particle size of the pigment granulate being <20 μm. The pigment granulate can be produced by dispersing the pigment and the compound of formula I in a solvent and then drying the dispersion obtained. The pigments according to the invention can be used for dying and/or the antistatic finishing in water-based paints and lacquer systems, dispersion on paints, printing inks, ink systems and coating systems.
