Highly anti-corrosive thin platelet-like metal pigments, a method of manufacturing the same, and metallic luster interference colored pigments which it based

PROBLEM TO BE SOLVED: To provide a highly corrosion-resistant flaky metal pigment which has high corrosion resistance even in a strongly alkaline atmosphere, has good dispersibility, and does not lose the metallic luster color unique to the flaky metal substrate. A surface of a flaky metal substrate such as aluminum flakes, titanium flakes, stainless steel flakes, and bronze flakes having a glittering feeling is treated with a phosphoric acid compound and / or a boric acid compound, and silicon, aluminum, zirconium titanium, and A highly corrosion-resistant flaky metal pigment coated with a layer containing tin hydrated oxide or the like.
