PURPOSE:To provide a metallic flake pigment having specific hiding power and excellent resistance to heat and corrosion and suitable for use as a pigment for metallic paint, consisting of a flaky powder composed of metallic titanium, a titanium alloy, metallic chromium or a chromium alloy. CONSTITUTION:A metallic flake pigment having hiding power of 1,000-15,000cm<2>/g comprises metallic titanium, a titanium alloy, metallic chromium or a chromium alloy. The pigment can be obtd. in the following manner. A flaky metallic powder obtd by a wet-process crushing method is classified and slurried. The slurry is subjected to solid/liquid separation. The filter cake is kneaded in a kneader or a ribbon mixer, and the metal content is adjusted to the predetermined value, thus obtaining the desired pigment. When the hiding power is outside the range defined above, it is difficult to use to pigment as one for paint.
