Title (EN) CATIONIC TITANIUM DIOXIDE PIGMENTS
(FR) PIGMENT CATIONIQUE A BASE DE DIOXYDE DE TITANE
Abstract:
(EN) 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.
(FR) L'invention concerne une composition comportant des particules de pigment cationique, qui comprend des particules de dioxyde de titane auxquelles sont liés un premier polymère cationique hydrosoluble et des particules de latex polymère cationique. Dans certains modes de réalisation, le latex cationique est fabriqué par le traitement d'un latex anionique avec un deuxième polymère cationique hydrosoluble, qui peut être identique ou différent par rapport au premier polymère cationique hydrosoluble. Ces compositions peuvent être utilisées dans des applications de fabrication de papier, en tant qu'additif interne ou solutions de couchage.
