A process for producing the heat-sensitive sheet suitable for the production of a stencil is described which is a simple process, makes it possible to readily form a porous substrate layer having a good fiber dispersibility on a thermoplastic resin film without intervening any adhesive layer and allows to carry out a single production line from beginning to end. The process comprises: a process characterized by dispersing polyester binder fibers on the surface of a thermoplastic resin film by an electrostatic flocking process, thermally compressing so as to form a porous substrate layer on a heat-sensitive sheet; another process comprises electrostatically flocking polyester binder fibers on the surface of a releasing member, then superimposing a thermoplastic resin film on the fibers-flocked surface on the releasing member, thermally compressing the superimposed film, and removing the releasing member to obtain a heat-sensitive sheet; and another process characterized by electrostatically flocking polyester binder fibers on the surface of a thermoplastic resin film and thermally compressing the fibers-flocked film to form a porous substrate layer on the thermoplastic resin film. <IMAGE> |
