  • Aqueous coating compositions pigmented with flake-form metallic effect pigments, processes for preparing them and use thereof for producing multicoat paint finish
    Patent number: 9249316
    Abstract: Disclosed are curable aqueous coating compositions comprising at least one polyurethane (A) as binder, at least one laminar metallic effect pigment (B), and at least one inorganic thickener C1) selected from the group of the phyllosilicates, and at least one organic thickener C2) selected from the group of the (meth)acrylic acid-(meth)acrylate copolymer thickeners and polyurethane thickeners, where the amount of B), based on the total binder content of the coating material composition is >9% by weight, the total solids based on the coating material composition is between 12.5% and 17% by weight, the total amount of the thickeners C1 and C2), based on the total binder content of the coating composition is <12.5% by weight, the weight ratio of C2) to C1) is >0.4, and the amount of B), based on the coating material composition, is between 1.2 and 2.3% by weight.
