摘要：The present invention relates to an aqueous dispersion (P) comprising at leastone polymeric resin (P1) and at least one polymeric resin (P2) different therefrom, wherethe polymeric resin (P1) is a polyamide and the polymeric resin (P2) is a polyester which isat least obtainable by reaction of at least one polymerized aliphatic C12-C24monocarboxylic acid with at least one diol and/or polyol, (P) being obtainable bydispersing of (P1) in water or an aqueous medium in the presence of (P2), and where (P1)has an acid number <10 mg of KOH per g of polyamide, and (P) contains at most 25 wt %,based on the total weight of (P), of one or more organic solvents, and also to an aqueouscoating composition comprising (P), at least one binder (A) comprising at least onepolymeric resin (A1), which is different from the polymeric resins (P1) and (P2), and at
least one pigment (B) for at least partly coating a substrate with a basecoat film.
