Alkoxylates And Amine-Containing Inorganic Pigment Dispersions

摘要

The invention relates to aqueous pigment preparations containing (A) 30 to 75 wt. % of at least one inorganic white or colored pigment or a mixture of different inorganic white or colored pigments; (B) 0.01 to 15 wt. % of at least one alcohol alkoxylate of the formula (I),;;in which R1 is a linear or branched alkyl or alkenyl group with 8 to 22 carbon atoms, m is a whole number from 1 to 20, and n is a whole number from 1 to 20; (C) 0.01 to 5 wt. % of at least one amine of the formula (II),;;in which R2 is a linear or branched alkyl or alkenyl group with 8 to 22 carbon atoms, said alkyl or alkenyl group being the same as or different from R1, A is an iminopropyl group —NH—CH2—CH2—CH2—, an oxyethyl group —O—CH2—CH2—, or an oxypropyl group —O—CH2—CH(CH3)—CH2—, and a is a whole number from 0 to 5, wherein the compound of formula (II) can be present in the form of an ammonium salt; and (E) water.
