Claim:
A pigment preparation comprising (a) 50% to 99% by weight of at least one pigment, (b) 1% to 50% by weight of an additive based on polyalkylene glycols, and (c) 0% to 10% by weight of an auxiliary selected from the group consisting of fillers, flame retardants, preservatives, light stabilizers, pigmentary and nonpigmentary dispersants, surfactants, antioxidants, defoamers, resins and antistats, all based on the overall weight of the pigment preparation, wherein the additive based on polyalkylene glycols is of formula (I) where Z′-[-(AO—) n —B-T-X—Y] m —Z (1) wherein AO is a C 2 -C 10 -alkyleneoxy unit, wherein A may be the same or different and n is greater than 1, B is a C 2 -C 10 -alkylene radical, T is —NR 1 —, where R 1 is a covalent bond to X, a hydrogen atom, a C 1 -C 18 -alkyl radical, a C 3 -C 7 -cycloalkyl radical, benzyl or a substituted or unsubstituted C 6 -C 18 -aryl radical, where the substituents are halogen, methyl, ethyl, propyl, butyl, methoxy, ethoxy, propoxy, butoxy, nitro or CF 3 , X is one of the groups where R is a hydrogen atom, a C 1 -C 18 -alkyl radical, a C 3 -C 7 -cycloalkyl radical, benzyl, or a substituted or unsubstituted C 6 -C 18 -aryl radical, where the substituents are halogen, methyl, ethyl, propyl, butyl, methoxy, ethoxy, propoxy, butoxy, nitro or CF 3 ; R 2 is a C 1 -C 18 -alkylene radical, a C 3 -C 7 -cycloalkylene radical, a substituted or unsubstituted C 6 -C 18 -arylene radical or a chemical combination thereof and the substituents are halogen, methyl, ethyl, propyl, butyl, methoxy, ethoxy, propoxy, butoxy, nitro or CF 3 ; or X is one of the following groups: wherein Y is a chemical bond or —NR 3 —, where R 3 is a covalent bond to X, a hydrogen atom, a C 1 -C 18 -alkyl radical, a C 3 -C 7 -cycloalkyl radical, benzyl or a substituted or unsubstituted C 6 -C 18 -aryl radical, where the substituents are halogen, methyl, ethyl, propyl, butyl, methoxy, ethoxy, propoxy, butoxy, nitro or CF 3 ; Z′ is an amino group, Z is a radical of the formula (AO) n —B-amino, n is a number between 1 and 200; and m is a number between 1 and 100.
