Abstract
The present invention relates to a low-viscosity pigment dispersion free from organic solvents and containing a fatty acid amidoalkoxylate as dispersing agent. The amidoalkoxylate is of the formula ##STR1## wherein R is an aliphatic hydrocarbon group having 7-22 carbon atoms, preferably 9-18 carbon atoms, A is an alkyleneoxy group having 2-3 carbon atoms, X is hydrogen or the group (A)n H, wherein A has the meaning stated above, n is a number of 1-15, the sum of all n being 3-20. The pigment dispersion can be used in paints based on water as well as organic solvents.
