SOLUTION: Provided is a composite oxide brown pigment represented by a composition formula xFeO-yAlO-zTiOand comprising a pseudo-brookite type crystal structure, in which x, y and z satisfy the following relation: x+y+z=1, 0.55≤x≤0.9, 0≤y≤0.4, and 0.05≤z≤0.35.EFFECT: We can provide a novel brown-type composite oxide pigment that can be used in a wide range of application areas such as road paving material, and building material including tile, concrete and mortar, paint, plastic material, or cosmetic, and that can solve the problems, which the conventional brown pigment holds, such as a point having magnetism, or a point having poor dispersibility in plastic, and yet that does not contain harmful elements.SELECTED DRAWING: None |
