ABSTRACT:
The invention relates to a pigment preparation containing (a) 50-99 percent by weight of at least one pigment, (b) 1 to 50 percent by weight of an additive based on polyalkylene glycols, and (c) 0 to 10 percent by weight of an auxiliary agent from among the group comprising fillers, fire retardants, preservatives, light-stability agents, pigmentary and non-pigmentary dispersing agents, surfactants, antioxidants, foam inhibitors, resins, and antistatic agents, the percentages being in relation to the total weight of the pigment preparation. The additive that is based on polyalkylene glycols corresponds to formula Z′-[-(AO—)n1—B-T-X—Y]m—Z (1), wherein AO represents a C2-C10alkyleneoxy unit, B represents a C2-C10alkylene radical, and T represents —NR—, X represents one of the groups (formula), and Y represents a chemical bond or —NR3—.
