  • Aqueous dispersion of at least two polymeric resins and aqueous coating composition comprising same for applying a topcoat
    Patent number: 10717110
    Abstract: The present invention relates to an aqueous dispersion (P) of at least two polymeric resins (P1) and (P2) which are different from one another, (P1) being a copolymer obtainable by copolymerizing ethylenically unsaturated monomers in the presence of at least one polyurethane resin having polymerizable carbon double bonds, and (P2) being a polyester having functional hydroxyl groups, which has an acid number of <25 mg of KOH per g of polyester, and (P) being obtainable by a process encompassing at least four steps (1), (2), (3), and (4), to an aqueous coating composition comprising the aqueous dispersion (P), to a process for at least partly coating at least one substrate metal surface, coated with at least one primer coat, with a topcoat, using the aqueous coating composition, and to an at least partly coated substrate obtainable by such a process.
