摘要:
The present invention relates to a process comprising the steps of a) contacting an aqueous dispersion of a TiO2 slurry containing adsorbing dispersant with an adsorbing latex to form a mixture, wherein the pH of the mixture of the TiO2 slurry and adsorbing latex are sufficiently high to inhibit interaction between the TiO2 and the adsorbing latex; then b) lowering the pH of the mixture of step a) sufficiently to promote interaction between the TiO2 and the adsorbing latex, thereby forming a composite. The process of the present invention provides for improved hiding and reduced grit for coatings compositions.

摘要:
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
