It is related to.

点があつた。(Prior art) Generally, this type of base paper is constructed by laminating a porous support and a thermoplastic synthetic resin film. Conventional thermoplastic synthetic resin films include polyester, polyvinyl chloride, and vinyl chloride. −
Vinylidene chloride copolymer, polyethylene, polypropylene, etc. are used. However, when a film made of the above-mentioned material is used and a thermal head of a thermal printer, thermal facsimile, etc. is used to perforate the film, the thermal head and the film are thermally fused, causing sticking noises during printing, and
There were problems such as irregular printing or damage to the heat-sensitive stencil paper. Therefore,
In order to prevent the thermal adhesion, some films have a release layer on the film surface, but with this, the molten material of the release layer forming agent adheres to the thermal head, significantly reducing the drilling performance of the thermal head. There was a drawback.

面積しか穿孔されないことがわかる。 Furthermore, when conventional heat-sensitive stencil paper perforated by a thermal head is printed on a rotary mimeograph machine, it is easy to tell at a glance that the characters on the printed matter are rough and are made up of a collection of dots, but the original printing of a thermal printer etc. Characters on printed matter obtained by means (thermal transfer carbon ribbon, heat-sensitive coloring paper, etc.) are delicate and difficult to distinguish whether they are formed by dots or not. This is because the thermal transfer carbon ribbon is melted by the thermal energy generated in each dot of the thermal head and spreads over an area larger than the size corresponding to the dot when it is transferred to the paper to be printed, or
It is thought that the printed characters become delicate because the area that is thermally colored by the thermal energy generated in each dot of the thermal head is larger than the size of the dot. However, with conventional heat-sensitive stencil paper that uses thermoplastic synthetic resin films such as polyester and polyvinyl chloride, when observing the perforated areas, the thermal energy generated in each dot of the thermal head is small, so the size of the dots varies. It can be seen that only the corresponding area is perforated.

Furthermore, the opening of the perforation should be sufficiently larger than the dot of the thermal head so that a clearer print can be obtained.

Natural fibers such as Manila hemp, paper mulberry, Japanese mulberry, and pulp may be used alone or in combination, and other materials capable of absorbing the molten resin of the polyvinylidene fluoride film can be used. And their basis weight is 6~

さは2μ以上9μ以下がよい。 As the polyvinylidene fluoride film of the present invention, a biaxially stretched film is used, and the stretching ratio varies depending on the thickness of the film, but it is preferably 100 to 300% in both the longitudinal and transverse directions. Further, since the thermal energy generated by a normal thermal head is about 2 mjoule per dot, if the film thickness exceeds 9 microns, the perforations formed by the dots will be insufficient. On the other hand, the thickness of the film
If it is less than 2μ, the perforation becomes too good, resulting in openings that are larger than necessary than the size of the dots in the thermal head, and the characters formed by the dots become thick and unclear. Therefore, the thickness of the polyvinylidene fluoride film in this invention is preferably 2 μm or more and 9 μm or less.

性もよい。(Function) When the heat-sensitive stencil paper having the above-mentioned structure is attached to a thermal printer or the like to make a plate, heat fusion between the vinylidene polyfluoride film and the thermal head is prevented, and the molten resin of the film is transferred to the thermal head. There is no risk of it sticking. Furthermore, the openings in the stencil paper obtained after plate making are perforated to a size larger than the size of each dot of the thermal head, and the printing clarity is good.

られた。 The heat-sensitive stencil paper is mounted on a desktop word processor ("Deskword" (model JX-20) manufactured by Silver Seiko Co., Ltd.) equipped with a thermal head 3, and the thermal head 3 perforates the film 2 to allow the ink to pass through. An opening 4 was formed for the purpose. At this time, the polyvinylidene fluoride film 2 and the thermal head 3 were not thermally fused and the plate making work could be carried out without any trouble. Furthermore, although two sheets of heat-sensitive stencil paper were made in succession, the molten resin of the film 2 did not adhere to the thermal head 3, and the perforation performance of the thermal head 3 did not deteriorate. Furthermore, when the stencil paper obtained after plate making was attached to a rotary mimeograph machine (Gestetner 4170) and printed, a printed matter was obtained that was comparable to printed matter directly printed with a thermal printer.

Furthermore, when holes were perforated using a thermal head in the same manner as in Examples, the molten resin of the film adhered to the thermal head, and the film was torn due to fusion. Furthermore, when the paper was attached to a rotary mimeograph machine and printed in the same way as in the example, the characters that had been perforated normally were rough and had noticeable dots, and the prints were less clear than those printed directly with a thermal printer. .

In addition, the porous support is made of tetrafluoroethylene resin (TFE), tetrafluoroethylene-6

る。Effects of the Invention As detailed above, this invention prevents thermal adhesion between the thermal head and the base paper by laminating a porous support and a polyvinylidene fluoride film with a thickness of 2μ to 9μ. In addition, since there is no need for a release layer, there is no risk of the molten material adhering to the thermal head, and the thickness of the base paper can be reduced accordingly. It has excellent effects in that it can be easily manufactured, and furthermore, printed matter can be obtained that is comparable to printed matter directly printed with a thermal printer.
