The present invention relates to aqueous dispersions comprising multistage-prepared polymers of olefinically unsaturated compounds and to the preparation and use thereof, in particular in the field of automobile coating.

Aqueous dispersions containing polymerizates produced in multiple stages and coating agent compositions containing same

Provided herein is a method for producing a multicoat paint system on a metallic substrate by producing a basecoat or a plurality of directly successive basecoats directly on a metallic substrate coated with a cured electrocoat system, producing a clearcoat directly on the one or the topmost of the plurality of basecoats, and subsequently jointly curing the one or the plurality of basecoats and the clearcoat, wherein at least one basecoat material used for producing the basecoats includes at least one aqueous dispersion which includes a polymer whose preparation includes successive radical emulsion polymerization of three mixtures of olefinically unsaturated monomers.

Method for producing a multi-layered coating

Provided herein is a mixer system for producing refinish compositions, more particularly for the sector of automotive finishing, including at least mutually different components (1), (2), and (3), namely component (1) as base varnish, component (2) as tinting base, and component (3) as rheology module, with at least one of components (1) to (3) including at least one aqueous dispersion including at least one polymer prepared by multistage emulsion polymerization, and at least one of components (1) to (3) including at least one aliphatic monoalcohol having 5 carbon atoms and/or at least one aliphatic monoalcohol having 6 carbon atoms.
