PROBLEM TO BE SOLVED: To provide a high-gloss silver white interference pigment and a bright interference color high-gloss interference pigment which are stable and easy to prepare. [Solution] An interference pigment based on a coated flaky substrate, (A) a layer of SiO 2 having a layer thickness of 5 to 350 nm; (B) It consists of a high refractive index coating made of titanium dioxide with a refractive index n exceeding 1.8, and (C) alternating layers of high refractive index and low refractive index having a layer arrangement of TiO 2 —SiO 2 —TiO 2. At least one of the interference systems, An interference pigment characterized by optionally comprising (D) an outer protective layer, wherein the flaky substrate is a glass flake, a mica flake or an aluminum oxide flake.
