Description of the Related Art A heat-sensitive stencil sheet is generally composed of a base paper obtained by laminating an ink-impermeable thermoplastic film directly or through an adhesive on a Japanese paper which is an ink-permeable porous support. Heat energy is applied to the film surface of the base paper to melt and perforate the film to form a plate of desired characters, figures, etc., and printing is performed using this plate. As this plate making method, a digital plate making method using a thermal head and a method of irradiating infrared rays or xenon flash light are already known. In particular, the digital plate-making method using a thermal head has advantages such as low printing cost when printing a large number of sheets and high-speed printing, as compared with electrostatic copying (PPC), and thus has rapidly spread. There is.

られない一つの要因となっていた。However, the conventionally used support for heat-sensitive stencil paper is often Japanese paper as described above, and in this case, the thermoplastic film produced at different places and the Japanese paper which is the support are used. Since it was necessary to integrate them, the heat-sensitive stencil sheet could not be manufactured as a series of operations in one place, and there was a difficulty in workability. In other words, the production of the heat-sensitive stencil sheet was very time-consuming, and this was one of the factors that prevented cost reduction.

A further object of the present invention is to provide a clear heat-sensitive stencil sheet without moire when the plate is made by a thermal head or the like.

好に行なうことができない。The ink-permeable, heat-resistant synthetic resin film used in the present invention has holes arranged in a row in which the pitches in the longitudinal and transverse directions are irregular, or holes in which the pore diameter is irregular. It may be a synthetic resin film which is a film having open pores or both of them and which has a heat shrinkage at 100 ° C. of not more than 1.0%. Especially, the pore size of this film is 5
Those in the range of 0 to 500 μm are preferable. Further, the open area ratio is preferably 20 to 60%. Porosity is 2
If it is less than 0%, the ink may not be sufficiently retained and the printed image may be faint. Further, when the porosity is more than 60%, the open part of the heat-resistant synthetic resin film which is the support,
The hole part of the thermoplastic film perforated by the thermal head formed on the upper part may partially overlap, and in this case, the diameter of the hole penetrating is larger than the hole part of the perforated thermoplastic film, This is because the printed image may be too large to obtain an accurate printed image. The thickness of the heat resistant synthetic resin film is preferably 5 μm or more.
This is because if the thickness is less than 5 μm, the obtained heat-sensitive stencil sheet has no strain and is easily broken. Also, in this case,
The transportability of the heat-sensitive stencil sheet deteriorates, and plate making and printing cannot be performed well.

It is only necessary that the synthetic resin film is a film having open pores or both of them, and that has a heat resistance of 100% or less at a heat shrinkage rate of 1.0% or less. Especially, the pore size of this film is 5
Those in the range of 0 to 500 μm are preferable. Further, the open area ratio is preferably 20 to 60%. Porosity is 2
Is less than 0%, ink Ru Kotogaa become blurred printing image can not sufficiently hold. Further, when the porosity is more than 60%, the opening part of the heat-resistant synthetic resin film as the support partly overlaps the opening part of the thermoplastic film formed by the thermal head formed on the support part. Sometimes
In this case, the diameter of the hole penetrating the hole of the thermoplastic film becomes larger than that of the hole, and the ink may be ejected too much to obtain an accurate printed image. The thickness of the heat resistant synthetic resin film is preferably 5 μm or more. This is because if the thickness is less than 5 μm, the obtained heat-sensitive stencil sheet has no strain and is easily broken. Further, in this case, the transportability of the heat-sensitive stencil sheet is deteriorated, and the plate making and the printing cannot be performed well.

とができる。Stencil sheet of the present invention according to the present invention, the support serving Lee
Since it is possible to manufacture a heat-resistant synthetic resin film that is transparent to ink and a thermoplastic film that is impermeable to ink, and to bond the both together in one place, as a series of operations,
Workability is greatly improved and cost can be reduced. In addition, since the film of the support has openings in which the arrangement in the longitudinal direction and the transverse direction is irregular and / or the pore diameter is irregular, it is possible to obtain a good printed image without the occurrence of moire.
