A b s t r a c t : The description relates to a physically drying water-based coating agent. It contains water, pigments, neutralising agents, conventional additives, small proportions of solvents and a binder mixture consisting of A) 10 to 90 wt.% polyurethanes with carbonate groupings and a glass transition temperature of <0°C based on reaction products of polyisocyanates with polyhydroxyl compounds, with a content of polyhydroxy polycarbonates and B) 90 to 10 wt.% of reaction products of carboxy-functional polycondensates and .alpha.,.beta.-olefinically unsaturated monomers with a glass transition temperature of >0°C in the form of an aqueous dispersion. The coating agent is particularly suitable for manufacturing lacquers for repairs in the motor vehicle sector.
