PURPOSE: Provided is silver-colored luster pigments based on multiply coated platelet-shaped substrates, which has at least one layer sequence of TiO2, a colorless coating and another TiO2 layer. Luster or effect pigments are widely used in industry, especially in automotive coatings, decorative coatings, plastic, paints, printing inks and cosmetic formulations. CONSTITUTION: The silver-colored luster pigment comprises a multiply coated platelet-shaped substrate and at least one layer sequence of layer (A) a high refractive coating consisting of TiO2 which has a thickness of 5-200 nm, layer (B) a colorless coating having a refractive index(n) of 1.8 or less and a thickness of 10-300 nm, and layer (C) a high refractive coating consisting of TiO2 which has a thickness of 5-200 nm, and optionally layer (D) an outer, protective layer.
