Abstract: An aqueous dispersion comprising at least one copolymer, the copolymer being preparable by initially charging an aqueous dispersion of at least one polyurethane, and then polymerizing a mixture of olefinically unsaturated monomers in the presence of the polyurethane, where a water-soluble initiator is used, the metered addition of the olefinically unsaturated monomers is effected in such a way that a concentration of 6.0% by weight, based on the total amount of olefinically unsaturated monomers, in the reaction solution is not exceeded over the entire duration of the reaction, and the mixture of the olefinically unsaturated monomers comprises at least one polyolefinically unsaturated monomer. The invention further relates to the use of the aqueous dispersion for production of coating materials, to a process for producing the aqueous dispersion, to a basecoat comprising the aqueous dispersion, and to the use of the basecoat for coating of automobile bodies and/or parts for installation on automobile bodies.
