Abstract: [Problem] To provide highly anti-corrosive thin platelet-like metal pigments which have high corrosion resistance and good dispersibility even in a strong alkaline atmosphere thereby maintaining the inherent metallic luster of thin platelet-like metal substrates. [Solution] The highly anti-corrosive thin platelet-like metal pigments in which the surface of thin platelet-like metal substrates are treated with phosphoric acid compounds and/or boric acid compounds, and further coated with a layer containing hydrated tin oxide.

Abstract: Highly anti-corrosive thin-platelet like metal pigments having high corrosion resistance and good dispersibility characterized in that the inherent metallic luster of the thin-platelet like metal substrates is maintained without demanding the original surface smoothness are provided. The highly anti-corrosive thin-platelet like metal pigments comprising, on the surface of thin-platelet like metal substrates treated with phosphoric acid compounds and/or boric acid compounds, one or more coated layers containing one or more hydrated metal oxides of one or more metals selected from the group consisting of silicon, aluminum, zirconium, titanium and tin.
