Modified inorganic pigments, methods of preparation, and compositions containing the same

摘要: A functionally modified pigment particle is prepared by mixing a flocculated of kaolin clay or calcium carbonate with modifier having charge sites opposite in sign to the pigment. Preferably, an aqueous suspension filter cake particles. The non-dispersed, partially dispersed neutralization strong base such as sodium carbonate. has pH range 6-9. Preferred modifiers are water insoluble dispersible latex binder, alkali soluble organic inorganic polymeric non-film forming plastic pigment, optical brightener, fluorocarbon, combination thereof. When mixed cake, become electrostatically bound
