<p>Production of cationized silica dispersion, comprises dispersing dry processed silica and a cationic resin in a polar solvent to produce a cationized silica dispersion. The concentration of dissolved silicic acid in the cationized silica dispersion at 25 [deg]C is measured and controlled to 200 ppm or less in terms of SiO 2. An independent claim is included for a cationized silica dispersion prepared by the process.</p> |
