Abstract
The titanium dioxide pigment of this invention has on the titanium dioxide particle surface a coating layer comprising a polyhydric alcohol and a hydrolysis product of an aminosilane compound, has a dispersibility of not more than 20 kg/cm as judged in terms of resin pressure increase, and is excellent in hydrophobicity and dispersibility. The pigment is useful as a coloring agent for plastics which requires good lacing resistance and dispersibility.
