    • The invention relates to a metal effect pigment, selected from the group consisting of aluminium in flake form, metal pigments in flake form having a copper content of 60 to 100 wt % and mixtures thereof, comprising a coating made of silicon oxide SiO
      x , where x is a number from 1 to 2, wherein the coated metal effect pigment contains both metal cations and anions containing phosphorus and/or sulphur, wherein the metal cations and the anions containing phosphorus and/or sulphur are each present independently of one another on the metal effect pigment surface and/or in the silicon oxide layer SiO
      x, and wherein the respective element ratio in at.% of metal cation MK and phosphorus P and/or sulphur S to silicon Si is defined according to formulas (I) and (II) 100% x (MK+P) / Si (I) and/or 100% x (MK+S) / Si (II) and overall is in a range from 0.5 to 35%. The invention further relates to the coated metal effect pigments which can be produced by means of the method according to the invention and also to the use thereof.
    • 本发明涉及金属效果颜料,其选自薄片形式的铝,铜含量为60至100重量%的薄片形式的金属颜料及其混合物,其包含由氧化硅SiO x制成的涂层,其中 x为1至2的数字,其中涂覆的金属效果颜料含有金属阳离子和含有磷和/或硫的阴离子两者,其中金属阳离子和含有磷和/或硫的阴离子彼此独立地在 金属效应颜料表面和/或在氧化硅层SiO x中,并且其中金属阳离子MK和磷P和/或硫S与硅Si的各自的元素比率按照式(I)和 II)100%×(MK + P)/ Si(I)和/或100%×(MK + S)/ Si(II),总体在0.5至35%的范围内。 本发明进一步涉及可以借助根据本发明的方法生产的涂覆的金属效果颜料,还涉及其用途。
