摘要：
The invention relates to goniochromatic luster pigments which are based on titanium dioxide-coated siliceous platelets heated in a reductive atmosphere. Said luster pigments contain at least one multilayer consisting of A) a colourless coating with a refractive index n ≤ 1.8 and B) a coating containing iron (III) oxide which absorbs visible light selectively, with a refractive index n ≥ 2.0. The invention also relates to the production and use of these pigments.
