    • The present invention relates to pigments comprising (A) a platelet-shaped substrate (S), (B) a coating comprising two different metal oxides having a difference in refractive index of at least 0.1, wherein the metal oxide having a higher refractive indexis the metal oxide MOH and the metal oxide having a lower refractive index is the metal oxide MOL, wherein the amount of MOH and the amount of MOL changes (continuously), (C) a coating comprising metal oxides MOH and MOL, wherein the amount of MOH and the amount of MOL changes (continuously), and (D) optionally an outer protecting layer; a process for their production and their use in paints, ink-jet printing, for dyeing textiles, for pigmenting coatings (paints), printing inks, plastics, cosmetics, glazes for ceramics and glass. The pigments can show enhanced colour chroma while maintaining the lightness of coventional interference pigments, or vice versa.
    • 本发明涉及包含(A)片状基材(S)的颜料,(B)包含折射率差异至少为0.1的两种不同金属氧化物的涂层,其中折射率较高的金属氧化物为 金属氧化物MOH和具有较低折射率的金属氧化物是金属氧化物MOL,其中MOH的量和MOL的量(连续地)变化,(C)包含金属氧化物MOH和MOL的涂层,其中MOH的量 并且MOL的量(连续地)变化,和(D)任选的外部保护层; 用于油漆,喷墨印刷,染色纺织品,着色涂料(油漆),印刷油墨,塑料,化妆品,陶瓷和玻璃的釉料的生产过程。 颜料可以显示增强的色度,同时保持常规干涉颜料的亮度,反之亦然。
