Abstract: Disclosed herein is an aqueous coating composition including an anionically stabilized binder,a color pigment, a polycarboxylic acid, and optionally a solvent. Further disclosed is a method for producing an inventive aqueous coating composition by adding a solution of polycarboxylic acid in a solvent to a coating composition including an anionically stabilized binder and color pigment.Additionally disclosed is a method for producing a multicoat paint system by producing a basecoat layer or at least two directly consecutive basecoat layers directly on a substrate optionally coated with a first coating layer, producing a clearcoat layer directly on the basecoat layer or the topmost basecoat layer, and jointly curing the basecoat layer(s) and the clearcoat layer. At least one of the basecoat materials includes the aqueous coating composition disclosed herein and/or an aqueous coating prepared by the disclosed method. A multicoat paint system obtainable by the method is additionally disclosed.
