POLYMER PARTICLES ADSORBED TO SULFATE-PROCESS TITANIUM DIOXIDE

摘要

Provided is an aqueous dispersion of particles of sulfate-process titanium dioxide, wherein polymeric particles are adsorbed onto said particles of titanium dioxide, wherein said polymeric particles comprise polymerized units of one or more P-acid monomer. Also provided is an aqeuous dispersion, wherein said aqueous dispersion is a grind made by a process comprising making a mixture that comprises water, polymeric particles, and particles of sulfate-process titanium dioxide, wherein said polymeric particles comprise polymerized units of one or more P-acid monomer, and wherein the volume ratio of said polymeric particles to said particles of sulfate-process titanium dioxide is 2.5:1 to 10:1.
