Document Type and Number:
Japanese Patent JP6972101
Kind Code:
B2
Abstract:
Described herein is an aqueous basecoat material including at least one aqueous polyurethane-polyurea dispersion (PD) with polyurethane-polyurea particles present in the dispersion and having an average particle size of 40 to 2000 nm and a gel fraction of at least 50%, and also including at least one aqueous dispersion (wD) which includes a polymer prepared by a successive radical emulsion polymerization of three different mixtures (A), (B), and (C), of olefinically unsaturated monomers. Also described herein are multicoat paint systems produced using the basecoat materials.
