Dispersing agent from renewable raw materials for binding agent-free pigment preparations

摘要

The invention relates to aqueous, binding agent-free pigment preparations, containing (A) 1.0 to 75.0 wt % of at least one organic or inorganic white or colored pigment or a mixture of various organic and inorganic white or colored pigments, (B) 0.01 to 8.0 wt. % of at least one phosphatide of formula (I), wherein R represents a group containing a carbon, hydrogen, oxygen atom and optionally a nitrogen and sulfur atom group, (C) 0.01 to 12.0 wt. % of a polyhydroxy fatty acid amide of formula (II) in which R3CO represents an acyl group of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmoleinic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid, behenic acid or erucic acid or their technical mixtures, R4 represents a hydrogen atom or a C1 to C4 alkyl group and q represents 3 and 4.;

1. An aqueous, binder-free pigment preparation comprising
(A) 1.0 to 75.0 wt % of at least one organic or inorganic white or chromatic pigment or a mixture of different organic and inorganic white or chromatic pigments, (B) 0.01 to 8.0 wt % of at least one phosphatide of the formula (I),  in which
R is an aliphatic radical comprising a total of up to 50 atoms selected from the group consisting of carbon, hydrogen, and oxygen atoms, and optionally nitrogen and sulfur atoms, (C) 0.01 to 12.0 wt % of a polyhydroxy fatty acid amide of the formula (II)  in which R3CO is an acyl radical of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitoelic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, pertroselinic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid, behenic acid, or erucic acid, or of technical mixtures thereof, R4 is a hydrogen atom or is a C1 to C4 alkyl group, and q is 3 or 4, and (G) water.
