ABSTRACT:
Fillers and pigments, such as clay, titanium dioxide, calcium carbonate, silicas, and silicoaluminates, can be rendered cationic by treating the fillers or pigments with the reaction product of a polyamine or polyamide and epichlorohydrin. The resulting water soluble cationic fillers or pigments are useful in the paper industry as fillers for paper and can also be utilized in coating paper.
