Abstract: The present invention relates to an aqueous blocked polyurethaneurea dispersion which is obtainable by reacting at least one polyisocyanate, one blocking agent for isocyanate groups, one polyamine having at least one carboxyl and/or carboxylate group, and water. Additionally provided by the invention are a coating composition comprising the aqueous blocked polyurethaneurea dispersion, the use of the aqueous blocked polyurethaneurea dispersion or of the coating composition for producing a coating, a coating obtainable using the aqueous blocked polyurethaneurea dispersion or the coating composition, and a method for producing the aqueous blocked polyurethaneurea dispersion.
