    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.
