Abstract
Provided herein is a pigmented aqueous basecoat material including an aqueous polyurethane-polyurea dispersion (PD) having polyurethane-polyurea particles present in the dispersion, an average particle size (volume average) of 40 to 2000 nm, and a gel fraction of at least 50 wt %. The polyurethane-polyurea particles, in each case in reacted form, include: at least one polyurethane prepolymer containing isocyanate groups and including anionic groups and/or groups which can be converted into anionic groups, and at least one polyamine comprising two primary amino groups and one or two secondary amino groups. The aqueous basecoat material includes a specific solvent composition. Also provided herein is a method of using basecoat materials including the dispersion (PD) and multicoat paint systems produced using the basecoat materials.
