The invention relates to a solid pigment preparation which contains, based on the total weight of the preparation (A), at least 60 wt.-% of a pigment component containing at least one pigment and/or a filler, (B) 1 to 39 wt.-% of at least one nonionic water-soluble surface-active additive which is based on polyethers selected from the group consisting of ethylene oxide homopolymers; ethylene oxide/propylene oxide block copolymers, the terminal blocks consisting of ethylene oxide entities; adducts of ethylene oxides with mono- or bifunctional amines or alcohols, the length of the ethylene oxide chain being selected such that the adduct is water-soluble; and adducts of ethylene oxide/propylene oxide block copolymers with mono- or bifunctional amines or alcohols, the terminal block consisting of ethylene oxide entities; (C) 1 wt.-% to 39 wt.-% of at least one nonionic surface-active additive which is based on polyethers selected from the group consisting of propylene oxide homopolymers; ethylene oxide/propylene oxide block copolymers, the terminal blocks consisting of propylene oxide entities; adducts of ethylene oxides with mono- or bifunctional amines or alcohols, the length of the ethylene oxide chain being selected such that the adduct is water-insoluble; and adducts of ethylene oxide/propylene oxide block copolymers with mono- or bifunctional amines or alcohols, the terminal block consisting of propylene oxide entities; and (D) 0 wt.-% to 10 wt.-% of an additive component containing at least one further additive which differs from the additives of components (A) and (B), the sum of the weight percentages not exceeding 100 wt.-%. The invention further relates to a method for producing the same and to methods for dyeing high-molecular materials. |
