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 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.

Composition de charge inorganique et procédé d'utilisation de ladite composition, ladite charge inorganique ayant été pré-traitée avec un agent de traitement anionique et un polymère cationique, afin d'obtenir une charge inorganique possédant un double traitement. Ces charges inorganiques s'utilisent avantageusement dans des procédés de fabrication de papier, où l'encollage, ainsi que d'autres propriétés, telles que la résistance et l'aspect optique, présentent une importance.
