Abstract: A modified clay paper coating composition comprising a montmorillonite clay having at least partially hydrolyzed aluminum chloride bonded thereto is made by treating montmorillonite clay with a non-aqueous solution of anhydrous aluminum chloride following by hydrolyzing with hot water. A paper substrate coated with this composition exhibits improved image light fastness when employed in a pressure-sensitive duplication system.
