PROBLEM TO BE SOLVED: To obtain the subject inexpensive pigment capable of producing by a simple method, exhibiting appearance having bright color and having metal gloss by coating stainless flake surface with a titanium compound comprising water-containing titanium dioxide and titanium dioxide. SOLUTION: The surface of stainless flake (preferably having 0.3-0.9μm thickness and 20-30μm average particle diameter) is coated with a titanium compound comprising a water-containing titanium dioxide and titanium dioxide. The pigment is preferably obtained by adding an inorganic salt of titanium to water, dissolving the inorganic salt in water by heating the mixture until 50 deg.C, dispersing stainless flake into water so as to become 10wt.% disperse concentration, adding the inorganic salt of titanium to the dispersion to control concentration as titanium dioxide to <=7wt.%, boiling the dispersion while stirring to hydrolyze the inorganic salt of titanium and successively carrying out neutralization, water washing, drying, grinding and baking of hydrolyzed material.
