  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 A 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°C to 100°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.

  本发明公开了一种用于热敏油印钢网的薄膜和一种热敏油印钢网，该钢网由多孔支撑物和层压在其上的薄膜组成。由于本发明的薄膜的晶体融合能 A Hu 为 3 - 11 cal/g，晶体融合起始点和晶体融合终止点的温度差 Tm 为 50°C 至 100°C，因此热敏性高，可以清晰地印刷字符和符号或数字，并且可以基本消除印刷字符的厚薄不均和明暗不均。此外，由于不需要将薄膜做得很薄，因此可以提高生产率和操作便利性。
