AQUEOUS EFFECT-PIGMENT PASTES CONTAINING A POLYMERIZATE, AND BASECOATS PRODUCED THEREFROM

The present invention relates to an aqueous effect-pigment paste comprising at least one effect 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, and to an aqueous basecoat which can be produced by admixing the effect-pigment paste with at least one aqueous component containing a binder, said component being suitable for producing the basecoat. The invention also relates to a method for producing a multi-layer paint using said basecoat and to the use of the polymerizate (b) for dispersing effect pigments within an aqueous effect-pigment paste. La presente invención hace referencia a una pasta de pigmento de efecto acuoso que comprende al menos un pigmento de efecto (a) y al menos un polímero (b) que se prepara mediante la sucesiva polimerización de emulsión radical de tres mezclas de monómero (A), (B) y (C) de monómeros olefinicamente insaturados en agua, a un material de capa base acuosa que se prepara al mezclar la pasta de pigmento de efecto con al menos un componente que contiene un aglutinante acuoso adecuado para preparar el material de capa base, a un método para producir un sistema de pintura multicapa mediante el uso de este material de capa base y para uso del polímero (b) para pigmentos de efecto dispersante dentro de una pasta de pigmento de efecto acuoso.
