摘要:
Phosphoric acid ester as dispersing agents in binding agent free-pigment preparations. The invention relates to aqueous, binding agent free-pigment preparations, containing (A) 1.0-75.0 wt.-% of at least one organic or inorganic white or coloured pigment or a mixture of different organic and inorganic white or coloured pigments, (B) 0.01 to 8.0 wt. % of at least one phosphoric acid ester of formula (IV), wherein R represents a linear or cross-branched, saturated or unsaturated C8 to C18− aliphatic hydrocarbon group, M represents a hydrogen atom or a sodium, potassium or ammonium ion, n is an integer of between 0-20 and m is an integer of between 0-20, (C) 0.01-12.0 wt.-% of a non-ionic surfactant which is a fatty acid ethanol amide ethoxylate of formula (V), wherein a represents an integer of between 3-50, and R1 represents C7−-C21− alkyl or -alkenyl and (G) water.
