    摘要： Process for preparing a dispersion comprising silicon dioxide particles and cationizing agents, by dispersing 50 to 75 parts by weight of water, 25 to 50 parts by weight of silicon dioxide particles having a BET surface area of 30 to 500 m2/g and 100 to 300 μg of cationizing agent per square meter of the BET surface area of the silicon dioxide particles, wherein the cationizing agent is obtainable by reacting at least one haloalkyl-functional alkoxysilane, hydrolysis products, condensation products and/or mixtures thereof with at least one aminoalcohol and water; and optionally removing the resulting hydrolysis alcohol from the reaction mixture. Also the process for preparing the dispersion, wherein the cationizing agent comprises one or more quaternary, aminoalcohol-functional, organosilicon compounds of formula III and/or condensation products thereof, wherein Ru and Rv are independently C2-4 alkyl group, m is 2-5 and n is 2-5.
