Abstract (en)
[origin: WO2015010016A1] 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 a zwitterionic polymer side chain comprising anionic and cationic groups. The dispersing agent may provide efficient pigment wetting and dispersion using relatively low and thus economical pigment amounts, with good opacity and good hiding characteristics, especially in titanium dioxide-containing coating compositions
