PURPOSE:To prevent a film from adhering by fusing with an original and prevent the clearness of images of a printed matter from being degraded, by laminating a porous base and a polyester film provided on its surface with a layer comprising a metallic salf of a fatty acid as a main constituent. CONSTITUTION:A porous base and a polyester film are laminated on each other by an emulsion or solution of a polyvinyl acetate resin or the like. Separately, a coating liquid is prepared by dissolving a metallic salt of a fatty acid in a solvent such as water, an alcohol and a hydrocarbon in a concentration of 0.5-3% at room temperature or with heating. Then, the coating liquid is applied to the polyester film, and is dried to provide a layer of the metallic salt of the fatty acid on the surface of the film, thereby producing a heat-sensitive stencil paper. Lithium, potassium, sodium or calcium salt or other metallic salt of stearic acid, pulmitic acid or other fatty acid is used as said metallic salt of the fatty acid. |
