  • Polycarboxylic acid-containing aqueous coating agent having an improved effect pigment alignment
    Patent number: 12234372
    Abstract: Described herein are an aqueous coating composition including at least one anionically stabilized binder, effect pigment, polycarboxylic acid, and solvent, and a method for producing a multicoat paint system by producing a basecoat directly on a substrate, producing a clearcoat directly on the basecoat, and then jointly curing the basecoat and the clearcoat. At least one of the basecoat materials includes the aqueous coating. Also described herein are multicoat paint system obtainable by this method, and the use of at least one polycarboxylic acid in an aqueous coating composition for improving the effect pigment orientation, or for color matching.

  • Aqueous polycarboxylic acid containing coating composition with improved leveling properties
    Patent number: 12173179
    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 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.
