Abstract

Described herein are an aqueous pigment paste including at least one color pigment (a) and at least one polymer (b) which is preparable by successive radical emulsion polymerization of three monomer mixtures (A), (B) and (C) of olefinically unsaturated monomers in water, an aqueous basecoat material which is preparable by admixing the pigment paste to at least one aqueous binder-containing component suitable for preparing the basecoat material, a method for producing a multicoat paint system using this basecoat material, and use of the polymer (b) for dispersing color pigments within an aqueous pigment paste.
