Abstract

The invention concerns a water-soluble polymer dispersant in which the polymer is formed from one or more olefinically unsaturated monomers and contains acid groups, which are carboxylic or sulfonic acid groups. The polymer has a polydispersity value below 1.5 and its molecular weight, defined as fully neutralized sodium salt, is between 1000 and 5000. The invention also concerns a pigment dispersion in a water-containing medium, which contains as dispersant for the pigment the aforementioned water-soluble dispersant. The invention also concerns a water dispersion paint that contains a pigment, a binder for the paint and the aforementioned dispersant for the pigment.
