ABSTRACT:
A process for producing a heat-sensitive stencil sheet (7) is disclosed, which makes it possible to readily form a porous substrate layer having a uniform and dense fiber dispersion on a thermoplastic resin film (3). The process is characterized by electrostatically flocking staple fibers (5) of 0.1-3 denier on a thermoplastic resin film (3) coated with a binder and by thermally compressing them (14) to form a porous substrate layer on the film. Since the porous substrate layer, having a good fiber dispersion, can be formed directly on the film by the electrostatic flocking process, it is possible to make the production process shorter, reduce the production cost and to improve the visual quality of the printed matter.
