Abstract: The present invention relates to an aqueous coating composition comprising at least one mixture (M) of at least one polymeric resin (P1) and at least one polymeric resin (P2), different therefrom, where (P1) is a polyamide and (P2) is a polyester which is at least obtainable by reaction of at least one polymerized aliphatic C12-C24-monocarboxylic acid with at least one diol and/or polyol, at least one binder (A) comprising at least one polymeric resin (A1), which is different from the polymeric resins (P1) and (P2), at least one pigment (B), where the polyamide used as polymeric resin (P1) has an acid number

Abstract: 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.
