It is also known that interference colors can be developed by controlling the thickness of the titanium dioxide coating layer of this pigment, but the coloring power is weak and it is unsuitable for use as a colored pigment. It is also known to further coat with an organic colored pigment to develop color, but this has drawbacks such as poor performance such as weather resistance.

成し、固溶させる方法がある。A method for forming a titanium dioxide coating layer in which nickel oxide and cobalt oxide or nickel oxide and antimony oxide are solidly dissolved on the surface of flaky mica particles is to first deposit a layer of titanium dioxide hydrate. There is a method in which a layer of colored metal oxide hydrate is then deposited, and these layers are fired simultaneously to form a solid solution.

ffi is preferably suspended at a concentration of 100-300 g/f and simultaneously or simultaneously with an aqueous solution of titanyl sulfate or titanium tetrachloride and an aqueous alkaline solution such as sodium hydroxide, potassium hydroxide or ammonia while maintaining the temperature at 80-100 °C. Alternate additions to bring the pH of the slurry from 4 to 9. Preferably, it is a method in which the titanium dioxide hydrate is hydrolyzed while being maintained at 6 to 8, and a required amount of the generated titanium dioxide hydrate is deposited on the surface of the mica particles. For this hydrolysis, urea may be used instead of alkali, or titanyl sulfate or titanium tetrachloride may be simply added to the slurry and heated to effect hydrolysis.
