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.

Aqueous dispersions containing polymerizates produced in multiple stages with polyurethanes as well as coating agent compositions containing same

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

The invention relates to aqueous dispersions comprising multistage-prepared polymers, and also to coating material compositions comprising them, preparable by multistage polymerization of olefinically unsaturated monomers, using an emulsifier and a water-soluble initiator, under conditions of starved feed polymerization, and using particular monomer mixtures in the individual stages. The invention also relates to a pigmented aqueous basecoat material comprising the aqueous dispersion of the invention, to the use of the aqueous dispersion of the invention in aqueous basecoat materials for improving adhesion, to a process for producing a multicoat paint system on a substrate, and to a multicoat paint system produced in accordance with the stated process.

Aqueous dispersions containing multistage produced polymers and coating agent compositions containing the same

An aqueous coating material comprising at least one epoxy resin as binder and at least one polyamine as curing agent, wherein said epoxy resin or at least one of the epoxy resins
