Abstract

The present invention provides methods of preparing a titanium dioxide pigment having improved gloss properties which involves heating an aqueous slurry of base titanium dioxide pigment to a temperature below about 75 °C, coating the base titanium dioxide pigment with a silica compound at a temperature below about 75 °C to form a silica coated titanium dioxide pigment; and coating the silica coated titanium dioxide pigment with an alumina compound at a temperature below about 75 °C to form the titanium dioxide pigment having improved gloss.
