摘要
The present invention relates to a process for the production of metal effect lacquerings having improved weather-resistance by the multilayered lacquering of various substrates, using a clear layer as top coat and a lacquer containing metal pigments to form the outer layer of the multilayered lacquering which is covered by the layer of clear lacquer, characterized in that the clear lacquer used is one the main binder of which is a two-component system consisting of: (a) a polyol component consisting essentially of polyester polyols having a low aromatic component content and optionally also polyacrylate polyols; and (b) a polyisocyanate component having biuret and/or isocyanurate groups, as well as aliphatically-bound isocyanate groups which may be blocked with isocyanate blocking agents. The present invention also relates to the substrates coated with these lacquers.
