    • The present invention relates to a method for producing corrosion-protected, particularly shiny, metal pigments, comprising a) providing a carrier layer, b) applying at least one metal layer made of a first metal, a first precious metal, or a first metal alloy by means of vapor deposition or applying said first metal, said first precious metal, or said first metal alloy, particularly in a vacuum, to a coatable surface of the carrier layer, and c) placing at least one acid, oxide, double oxide, oxide hydrate, sulfide, halide, nitride, carbide, carbonitride, boride, silicide, oxyhalide, and/or salt of a second metal in the metal layer by treating the metal layer with an aqueous system comprising at least one acid, oxide, double oxide, oxide hydrate, sulfide, halide, nitride, carbide, carbonitride, boride, silicide, hxyhalide, and/or salt of the second metal, wherein the second metal represents an element of the fourth and/or fifth group of the periodic system of elements or a mixture thereof, d) dissolution of the formed metal layer from the carrier layer, and e) disintegrating the dissolved metal layer while maintaining the metal pigments. The invention further relates to metal pigments obtainable using said method and plastic and paper products and coating compositions comprising the metal pigments according to the invention. The invention additionally relates to a method for producing particularly corrosion-protected, glossy plastic substrates comprising metal pigments, particularly metal pigments according to the invention, and plastic substrates obtainable using said method.
    • 本发明涉及一种方法,用于生产防腐蚀的,在包括:a)提供载体层特定光泽,金属颜料,b)将第一金属,第一贵金属或通过气相沉积的装置的第一金属合金中的至少一个金属层或沉积该第一金属, 此第一贵金属或第一金属合金,特别是在真空下,在载体层的可涂布的表面,以及c)引入至少一种酸,一种氧化物,双氧化物,氧化物水合物,硫化物,卤化物,氮化物,碳化物,碳氮化物,硼化物,硅化物, 卤氧化物和/或在金属层中的第二金属的盐通过用含有至少一种酸,一种氧化物,双氧化物,氧化物水合物,硫化物,卤化物,氮化物,碳化物,碳氮化物,硼化物,硅化物,卤氧化物和含水系统处理该金属层 /或第二金属的盐,其中 其第二金属是第4族和/或元素或它们的混合物的汽提从所述载体层中的金属层中形成的周期表,D)的5,和e的粉碎分离金属膜,得到金属颜料的元素)。 此外,本发明,通过该方法,以及塑料和纸制品,以及涉及含有本发明的金属颜料的涂料组合物得到的金属颜料。 此外,本发明根据本发明,金属颜料,以及由该方法得到的塑料基材涉及用于生产特别耐腐蚀,光泽的塑料基质,包含的处理,尤其如此。
