Abstract
In one aspect, the invention provides a titanium dioxide pigment. The titanium dioxide pigment comprises a plurality of titanium dioxide particles, and a polymer deposited on the titanium dioxide particles for inhibiting agglomeration of the titanium dioxide particles in an aqueous based coating formulation. The titanium dioxide particles have anchoring moieties associated therewith for facilitating anchoring of the polymer to the particles. The polymer is a copolymer having anchoring groups for attaching to the anchoring moieties associated with the titanium dioxide particles and hydrophobic end groups for attaching to the resin of the coating formulation. In another aspect, the invention provides a method of manufacturing a titanium dioxide pigment.
