Abstract
The invention relates to aqueous, binder-free pigment preparations containing at least one anionic fatty amide of formula (I), where R is a linear or branched, saturated or unsaturated C7 to C17-aliphatic hydrocarbon group, A is an anionic group, such as a sulphate, phosphate or methyl-carboxylate group or a sulfosuccinic acid half-ester group, and n represents a whole number between 1 and 30.
Claims17
An aqueous binder-free pigment preparation comprising
- (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 anionic fatty acid amide of formula (I),
- where
- R is a linear or branched, saturated or unsaturated C7 to C17 aliphatic hydrocarbyl moiety,
- A is an anionic group, and
- n is an integer from 1 to 30, and
- (G) water,
- wherein the pigment preparation is free from polymers or resins dissolved or dispersed in a suitable solvent and dries physically, chemically, thermally, oxidatively or by radiative curing.
