Abstract
An iridescent multilayer pigment having at least two or more layers of metal oxides containing one or more metals selected from Ce, Sn, Ti, Fe, Zn and Zr which are coated onto the surface of thin platelet-like substrates. The inventive pigments show high brilliance and high chroma, in particular in cases in which thin platelet-like substrates having a fine average particle diameter are used. The pigment is useful in paints, printing inks, lacquers, plastics, dopants for laser marking, non-dusting pigment products, non-dusting pigment granules or cosmetics.
