  • Patent number: 8915998
    Abstract: 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 ?m. 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.
