CATIONIC TITANIUM DIOXIDE PIGMENTS

摘要

A composition containing cationic pigment particles includes titanium dioxide particles to which are bound a first water-soluble cationic polymer and cationic polymer latex particles. In some embodiments the cationic latex is made by treating an anionic latex with a second water-soluble cationic polymer, which may be the same as or different from the first water-soluble cationic polymer. The compositions may be used in papermaking applications, both for internal addition and or coatings.
