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 PA1 (a) 1.0 to 50.0% by weight of acrylonitrile, methacrylonitrile or a mixture thereof PA1 (b) 0.1 to 10.0% by weight of a compound having 2 or more polymerizable olefinic double bonds; PA1 (c) 40.0 to 98.9% by weight of other copolymerizable compounds, and PA1 (d) up to 5% by weight cellulose ester; with the total amount of the components a, b, c and d being 100% by weight.
