PURPOSE:To enhance affinity between an ink and a porous tissue paper and reduce waste in trial printing, by applying a surface active agent to the porous tissue paper, in a heat-sensitive stencil paper consisting of a laminate of a film and a porous tissue paper. CONSTITUTION:A polyester film 5 and a porous tissue paper 2 consisting, for example, of polypropylene fibers of 0.03 denier are laminated on each other by using polyvinyl acetate 3, then the resultant laminate is impregnated with a solution of a surface active agent from the side of the tissue paper 2, and is dried at a temperature at which the film 5 is not denatured. Pelex NBL, Emalgen 105, Emal 80 or the like may be used as a surface active agent, which is appropriately selected in accordance with the materials of the ink 7 and the porous tissue paper 2. |
