Abstract:
1. A solid pigment preparation, comprising, based on a total weight of the preparation: (A) at least 60% by weight of a pigment component comprising one or more pigments and optionally a filler; (B) 1% by weight to 39% by weight of at least one nonionic water-soluble surface-active additive having an HLB value of greater than 10 and comprising at least one polyether selected from the group consisting of an ethylene oxide homopolymer, an ethylene oxide-propylene oxide block copolymer with terminal blocks consisting of ethylene oxide units, an ethylene oxide adduct on at least one mono- or bifunctional amine or alcohol with a length of ethylene oxide chain being such that the adduct is water soluble, and an ethylene oxide-propylene oxide block copolymer adduct on at least one mono- or bifunctional amine or alcohol with at least one terminal block consisting of ethylene oxide units; (C) 1% by weight to 39% by weight of at least one nonionic surface-active additive having an HLB value of less than 10 and comprising at least one polyether selected from the group consisting of an ethylene oxide-propylene oxide block copolymer with terminal blocks consisting of propylene oxide units, and an ethylene oxide-propylene oxide block copolymer adduct on at least one bifunctional amine with a terminal block consisting of propylene oxide units; and (D) 0% by weight to 10% by weight of an additive component comprising at least one further additive other than additives of components (A) and (B), wherein a sum total of weight fractions does not exceed 100% by weight.
