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.
