USE OF HIGH MOLECULAR WEIGHT SULFONATE AS SECONDARY DISPERSANT FOR STRUCTURIZED KAOLIN

摘要

This invention relates to a heat-stable dispersed aqueous slurry of chemically bulked hydrous kaolin clay pigment and an effective amount of dispersant comprising water soluble anionic sulfonate, the bulked clay being one obtainable by adding cationic material to hydrous kaolin clay in the presence of water to flocculate said clay.
