Abstract
A dry clay composition consisting of an alkaline earth bentonite is activated by mixing with an aqueous activating solution containing an alkali metal or ammonium salt of a sequestering agent selected from phosphonate, hydroxy carboxylic acids, amino carboxylic acids and di or tri carboxylic acids. Also claimed is a paper-making process comprising forming a cellulosic suspension, mixing an activated bentonite dispersion into the suspension, draining water from the suspension and drying the wet sheet obtained. The bentonite dispersion is made by the above process, optionally followed by dilution.
