摘要： Aqueous dispersions including multistage-prepared polymers of mixtures of olefinically unsaturated compounds are disclosed. The aqueous dispersions include at least one polyurethane containing olefinically unsaturated groups. Production and use of the aqueous dispersions, particularly in the field of automotive finishing, is disclosed. The disclosure further relates to an aqueous basecoat material including the multistage-prepared polymers, and also to a method for producing a multicoat paint system using the aqueous basecoat material.

摘要： 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.
