Abstract

540,148. Coated fabrics. RAITH, E. April 5, 1940, No. 6220. Convention date, April 6, 1939. [Class 140] [Also in Group XVI] Carbon paper is provided on the reverse side with a coating of chlorinated rubber having incorporated therein a fine insoluble powder, such as kieselguhr, argillaceous earth, chalk, lithopone or metal, for increasing the surface's friction and thereby preventing slipping of the copy sheet. The particles of powder are preferably of such size as to project from the surfaces of the coating.
