  • Patent number: 4914148
    Abstract: Basecoating compositions for preparing multilayered protective and/or decorative coatings comprise aqueous dispersions which contain(a) as film-forming material one or more polyurethane resins having an acid number of from 5 to 70, which has been prepared by preparing from(A) liner polyetherdiols and/or polyesterdiols having a molecular weight of from 400 to 3,000(B) diisocyanates and(C) compounds which contain two groups which are reactive toward isocyanate groups, one or more of the compounds used as component C having one or more groups capable of anion formation which have preferably been neutralized before the reaction with a tertiary amine,an intermediate which as terminal isocyanate groups and whose free isocyanate groups have subsequently been reacted with a polyol which contains three or more hydroxyl groups, preferably a triol,(b) pigments and(c) further customary additives.

  • Patent number: 4413036
    Abstract: A two-layer metal-effect coating, composed of a base layer which contains metal pigments and of a clear top coating, at least the base layer being obtained from a coating agent which contains as the film-forming binder a polymer resin which was obtained by copolymerizing olefinically unsaturated compounds, wherein the polymer resin is obtained by copolymerizing(a) 1.0 to 50.0% by weight of acrylonitrile, methacrylonitrile or a mixture thereof(b) 0.1 to 10.0% by weight of a compound having 2 or more polymerizable olefinic double bonds;(c) 40.0 to 98.9% by weight of other copolymerizable compounds, and(d) up to 5% by weight cellulose ester; with the total amount of the components a, b, c and d being 100% by weight.
