    摘要： 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.

    摘要： The invention provides titanium dioxide pigments for plastics resin compositions which are excellent in dispersibility, light resistance, and weather resistance and little cause surface imperfection. In particular, the invention provides a titanium dioxide pigment suitable for general-purpose plastics resin compositions which can attain excellent dispersion and lacing resistance even when blended in a high concentration; a titanium dioxide pigment suitable for engineering plastics resin compositions which can attain dispersion properties, silver streaking resistance, inhibition of reduction in molecular weight, and thermal discoloration resistance at high levels; a process for the production of the pigments; and resin compositions containing the pigments. A titanium dioxide pigment for plastics resin compositions, characterized in that each titanium dioxide particle has a dense hydrous silica coat covering its surface and an organic compound coat formed on the silica coat not through an interlayer.
