るようになっている。(Prior Art) Heat-sensitive stencil printing base paper, which is made by adhesively laminating a glass film that is easily perforated by heating and a base material such as porous thin paper or gauze that is permeable to ink, is widely used in the field of light printing. A thermal head is often used for perforation of this type of base paper. In order to increase the perforation plate-making speed with a thermal head, it is necessary to increase the output of the head, that is, to raise the operating temperature, but increasing the output is difficult due to the structure, so plate-making can be done with a low-output thermal head. Heat-sensitive stencil printing base papers with high heat sensitivity have become particularly desirable.

の１〜１０ミクロンの薄い延伸フィルムが用いられる。The heat-shrinkable plastic film used in the present invention is a thin plastic film that is easily perforated by heating. The material may be one of vinylidene chloride copolymers, polyesters, copolyesters, polyamides, copolyamides, etc., as described in JP-A-61-116595, JP-A-59-16795, etc. A thin stretched film of ~10 microns is used.

望ましい。These include diethylhexyl phthalate, phosphate ester-based tricresyl, tri-2-etherhexyl, triphenyl phosphate, and adipic-ester-based di-2-ethylhexyl adipate. The most preferred method for bringing the plasticizer into contact with the film is to incorporate it into the adhesive. If it is blended into the adhesive, the plasticizer can be easily brought into contact with the film and absorbed without using extra means for using the oJ plasticizer. In addition, it can be directly coated on a film or coated on an ink-permeable substrate and brought into contact with it. In the film of Bl plastic
The transition of \ usually takes some time, so some aging is performed. During aging, heating is desirable.

感度を向上させることができる。(Function) Plasticizers have the function of lowering the softening temperature of the film and lowering the melt flow viscosity, but it is very difficult to make a thin stretched film using a resin that has been mixed with multiple plasticizers in advance. Have difficulty. According to the method of the present invention, the plasticizer is contacted and absorbed after forming the stretched film, so there is no difficulty in forming the film, the softening temperature of the film is lowered, the melt flow viscosity is lowered, and the heat-sensitive stencil plate 1'' is printed. The drilling sensitivity of the original material can be improved.

がわかった。Example 1 A 2 micron thick heat-shrinkable biaxially stretched film of copolymerized polyester that does not contain a plasticizer and 8.51/17 L'' manila hemp tissue paper with high ink permeability were superimposed, and from the thin paper side, As a photopolymerization initiator, 5 parts of Irgacure 184 manufactured by Chinogu Geigy Co., Ltd. and 4 parts of dibutyl phthalate were used.
0%, polyvinyl acetate 15%, and UV curing adhesive (
A methanol bath solution containing 40% of Toagosei Aronix M1100) was applied with dry violet to dry it, and the adhesive was cross-linked and cured by applying ultraviolet rays from the film side. It was left for a week to age. The heat-sensitive stencil printing base paper obtained in this way was printed using the thermal head of a Casio Word HW100OJS printer manufactured by Casio Computer Co., Ltd., which is a commercially available personal word processor, at a density of 8 and under the conditions of business luck, and then printed on a printing machine Lingraph AP7200 manufactured by Riso Kagaku Kogyo Co., Ltd. When printed properly, a good image was obtained. Although the thermal head of a commercially available personal word processor does not have a moderate output, it was found that it was sufficient for plate making. For comparison, the mixing ratio of the adhesive was the same except that dibutyl phthalate was not mixed, and the coating lid was 1.2 + @ / m', that is, the upper tU, and the same as the above example, except that the upper tU was violet without dibutyl phthalate. A base paper was prepared in the same manner and an attempt was made to perform plate printing using the same by, but the perforations were insufficient and a complete image could not be obtained. In other words, it was found that this base paper could not be made into a plate using an f-maru head that did not have a very large output without causing the plasticizer to be absorbed by contact.
