ABSTRACT:
A stable aqueous pigment slurry and a process for preparing same. The slurry contains about 50 to 90 wt. %, based on the weight of the slurry, of a pigment such as titanium dioxide and about 0.2 to 3.0 wt. %, based on the weight of the slurry, of a smectite clay such as bentonite, hectorite or montmorillonite. Preferably, the pigment slurry also contains about 0.1 to 2.0 wt. %, based on the weight of the slurry, of a dispersant. The process involves admixing a pigment slurry and a smectite clay slurry and preferably also the dispersant by milling the three components together under high shear conditions.
