ABSTRACT:
Disclosed are novel organic pigments adapted particularly for use as fillers for paper. The organic pigments are finely divided particles obtained by graft copolymerizing an ethylenically unsaturated monomer, such as styrene, onto a water-soluble cationic prepolymer in an aqueous solution and in the presence of a free-radical polymerization initiator.
