The heat-sensitive stencil printing base paper used in the above-mentioned conventional stencil printing method generally has several μm on the surface of an ink-permeable support.
It is formed by laminating a thin thermoplastic film of about m with an adhesive or the like, but recently, in order to improve the image quality of printed matter, a plate making method using a thermal head has become mainstream,
In addition, the size per one dot tends to be miniaturized. Also, the amount of heat per dot tends to be small, and higher performance is required for the heat-sensitive stencil printing base paper. Conventionally, a biaxially stretched polyethylene terephthalate (PET) film or the like is widely used as a thermoplastic film.
T) In order to obtain a sufficient print density by thermally perforating a film or the like, it is necessary to increase the energy supplied to the thermal head. Conventionally, the adhesive between the thermoplastic film and the ink-permeable support has been generally bonded using an adhesive. However, since an adhesive resin or the like exists between the thermoplastic film and the ink-permeable support, the heat is not applied. There is a disadvantage that the thermal perforation of the plastic film is impaired, and that it penetrates between the fibers of the ink-permeable support and impedes the permeation of the ink.

By using the heat-sensitive stencil printing base paper according to the present invention, a heat-sensitive stencil printing base paper having excellent performance and sensitivity can be provided even when the energy supplied by the thermal head is small. In addition, as a method of bonding the ink-permeable support and the thermoplastic film, the support-side surface of the thermoplastic film is heat-fused and then heat-fused with the ink-permeable support, so that the heat-sensitive stencil printing base paper is a thermoplastic film. It is possible to provide a heat-sensitive stencil printing base paper having excellent performance and sensitivity without impairing the heat-perforability of a portion. A particularly excellent heat-sealing method is a method in which a heated ink-permeable support is brought into contact with the surface of the thermoplastic film on the support side and is melted by heating. By this method, the ink on the support-side surface of the thermoplastic film is produced. It is possible to prevent thermal melting of the non-contact portion of the permeable support, and to provide a heat-sensitive stencil printing base paper having excellent performance and sensitivity without impairing the thermal porosity of the thermoplastic film portion. When the temperature of the ink-permeable support to be heated is higher than the melting temperature of the thermoplastic film to be heat-fused by more than 5 ° C. , the thermal perforation of the thermoplastic film is reduced by the contact of the heated ink-permeable support. Significantly worsens. In particular, when it is significantly deteriorated, the thermoplastic film is in a state of being perforated by the ink-permeable support, and cannot be used as a heat-sensitive stencil printing base paper. When the temperature of the ink-permeable support to be heated is lower than the melting point of the thermoplastic film to be heat-fused, the thermoplastic film does not melt due to the contact of the heated ink-permeable support, Thermal fusion of the plastic film and the ink-permeable support is not possible. Therefore, the temperature of the ink-permeable support to be heated is 0 to the melting point of the thermoplastic film to be heat-sealed.
By being characterized by a high temperature of 5 ° C., it is possible to provide a heat-sensitive stencil printing base paper having excellent performance and sensitivity without impairing the thermal porosity of the thermoplastic film portion. When thin paper mainly composed of natural fibers is used as the ink-permeable support to be heat-sealed, the heat-sealing property between the thermoplastic film and the ink-permeable support is not possible due to poor fusion property with the thermoplastic film. . When thin paper made mainly of synthetic fiber is used as the ink-permeable support to be heat-sealed, the fusion property with the thermoplastic film is good, and the heat-fusion of the thermoplastic film and the ink-permeable support is possible. Thus, it is possible to provide a heat-sensitive stencil printing base paper having excellent performance and excellent performance in sensitivity and adhesiveness without impairing the heat piercing property of the thermoplastic film portion.
