Abstract (en)
[origin: WO9532335A1] An inorganic filler composition and a method for the use thereof wherein the inorganic filler has been pre-treated with an anionic treating agent and a cationic polymer to produce a dual treated inorganic filler. The surface-treated inorganic filler materials of the present invention are particularly suitable for use in papermaking processes where sizing and other properties, such as strength and optical performance are important.
