Abstract: A film for thermal porous printing paper and a thermal porous printing paper composed of the film and a porous support are disclosed. The film comprises a biaxially oriented polyester film having a crystal melting energy, Delta Hu, of 3 to 11 cal/g and showing a difference between the crystal melting completion temperature and crystal melting initiation temperature, delta Tm, of 50 to 100 deg.C. Hence it has such a high heat sensitivity that characters and solid images are distinctly recorded with substantially no unevenness in thickness or density of the images. In addition, since it eliminates the necessity of reducing the thickness of the film.

Abstract: A film for heat-sensitive mimeograph stencil and a heat-sensitive mimeograph stencil comprising a porous support and the film laminated thereon are disclosed. Since the film of the present invention has an energy of crystal fusion .DELTA. Hu of 3 - 11 cal/g and has a difference Tm in temperature of the crystal fusion-starting point and the crystal fusion-terminating point of 50.degree.C to 100.degree.C, the heat sensitivity is high, so that the characters and symbols or figures can be printed clearly, and the unevenness in the thickness and the light and shade of the printed characters may substantially be eliminated. Further, since it is not necessary to make the film thin, productivity and ease of handling may be promoted.
