Abstract
A polymer-encapsulated pigment dispersion is prepared from a mixture of (a) a carrier; (b) pigment particles; and (c) a polymeric dispersing agent having a polymer backbone, and an alkali-swellable copolymer component. The dispersing agent may provide efficient pigment wetting and dispersion using relatively low and thus economical dispersant amounts, and subsequently enable formation of polymer-encapsulating pigment dispersions that, when used in coatings, provide good opacity and good hiding characteristics, especially in titanium dioxide-containing coating compositions.
