| abstract |
The titanium dioxide pigment of the present invention comprises titanium dioxide particles, the coating layer containing the aluminum phosphate compound and the coating layer containing the hydrolyzate of the organosilane compound, on the surface of the particles, in which a difference in water content between 100°C and 300°C, determined by the Karl Fischer method, is not greater than 1500 ppm, and is thus excellent in light fastness, hydrophobicity and dispersibility. In particular, the titanium dioxide pigment of the invention is extremely advantageous as a colorant for plastics, which requires light fastness (resistance to discoloration) lacing resistance and dispersibility, to a high degree. |
