Abstract (en)
[origin: WO2018172476A1] The present invention relates to an aqueous pigment paste comprising at least one color pigment (a) and at least one polymerizate (b) which can be produced by the sequential radical emulsion polymerization of three monomer mixtures (A), (B) and (C) of olefinically unsaturated monomers in water. The invention also relates to an aqueous basecoat which can be produced by admixing the pigment paste with at least one aqueous binder-containing component that is suitable for producing the basecoat. The invention further relates to a method for producing a multi-layer paint using said basecoat and to a use of the polymerizate (b) for dispersing color pigments within an aqueous pigment paste.
