Abstract

The invention relates to an aqueous coating material. The aqueous coating material comprises 5-95% by weight (based on the overall binder content) of a binder component a) and 5-95% by weight (based on the overall binder content) of a binder component b). The binder component a) is obtainable by free-radical polymerization of an aqueous dispersion of a polyurethane resin with ethylenically unsaturated monomers and in the presence of a water-insoluble initiator. The binder component b) is obtainable by polymerizing ethylenically unsaturated monomers in an organic solvent or in a mixture of organic solvents and in the presence of a polyurethane resin and converting the resulting binder component b) into an aqueous dispersion.
