Disclosed are high solids content bentonite clay coating formulations for use in the production of receiver sheets for carbonless copying systems. The formulations comprise an acid-leached bentonite-type clay and an inactive clayey material such as chalk or a mixture of chalk and kaolin. The formulations are effective for use in the "on machine" blade coating of a paper substrate to more efficiently produce receiver sheets for carbonless copy systems. |
