Plastic substrate, comprising metal pigments, and method for their preparation, as well as corrected, ion protected metal pigments, and production method thereof

摘要

The present invention relates to a process for the production of corrosion-protected, in particular glossy, metal pigments, comprisinga) providing a carrier layer,b) applying at least one metal layer of a first metal, a first noble metal or a first metal alloy by means of vapor deposition or application of this first metal, of this first noble metal or of this first metal alloy, in particular in the vacuum, on a coatable surface of the carrier layer, andc) the introduction of at least one acid, of an oxide, said 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, an oxide, lithium-containing double oxide, oxide - hydrate, sulfide, halide, nitride, carbide, carbonitride, boride, silicide, oxyhalide and / or salt of the second metal, wherein the second metal an element of the 4. group and / or the 5. group of the periodic table of the elements or mixtures thereof which,d) ablpsen of the formed metal layer of the carrier layer ande) comminution of the separated metal layer with retention of metal pigments.The present invention further relates to the metal pigments obtainable by this process, as well as plastic - and paper products, as well as coating compositions, comprising the novel metal pigments. ..
