に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides heat-sensitive materials for perforating the strokes of characters and figures on a manuscript by heating with infrared irradiation, etc., to create an original plate for rotary printing presses, scroll printing plates, and stencil printing. This relates to base paper for stencil printing.

れる。If a manuscript with predetermined characters, figures, etc. written on it is superimposed on a heat-sensitive stencil printing base paper made of a laminate of a film and a support such as paper, and S is added to it by infrared irradiation, etc.,
The parts of the heat-sensitive stencil printing base paper that match the characters and figures of the original document absorb light and easily generate heat, and the film in those parts is melted and perforated by the heat generated.

のである。On the other hand, the physical properties of this film are the causes of wrinkles and curls during storage and plate making of heat-sensitive stencil printing base paper formed by the film and the stretching layer of the support (for example, paper). Therefore, a lot of research has been carried out on fill AK as a constituent element of heat-sensitive stencil printing base paper, and the present inventors have diligently investigated (
As a result of repeated IE research, we have discovered a film and its physical properties that can provide good perforation strokes without wrinkling or curling during storage and plate making, and by using this, we have achieved the present invention. It has been completed.

いのである。In the present invention, the type of film is limited to poly7 ethylene terephthalate. In other words, in heat-sensitive stencil printing base paper in which the film side is heated and melted by infrared irradiation or the like and perforations are made there, the film material must be made of as much heat as possible in order not to require excessive thermal energy during the perforation. The thinner the hole, the better, but in general, the thinner the hole, the more likely the flatness will be damaged by the heat during drilling, and the result will be a 7-hole hole that is even smaller.
One plate lacks the strength to withstand the force applied during TI plate printing, and as a result, the number of sheets printed per printing is extremely small, making it impossible to put it to practical use. Even if the polyethylene resin phthalate film is jiggly, its flatness will not be affected by the heat during perforation, and it has excellent printing durability. The polyester resin film used in the present invention, which is tested by providing paper, has a heat shrinkage rate ratio of /, 3 to 3 in the vertical and horizontal λ directions.
1. The thickness is 2.0 to 3. It must be something that satisfies jμ. That is, if the heat shrinkage ratio is outside the range of 7.3 to /, lf, the back hole ii! !
Distortion is likely to occur in the original, and therefore, in stencil printing using the original plate, it is not possible to produce clear prints of characters and figure pairs.

である。However, in the present invention, both the heat shrinkage ratio and the thickness of 20 to 3.3 microns must be satisfied at the same time. Zunawara, 3. If the film is thicker than 2.0μ, excessive thermal energy is required to melt and perforate it, and it is often difficult to reliably perforate the film with normal infrared irradiation. Polyethylene terephthalate [1] (Even if it is one, the original plate, which is subject to perforation, is strong enough to distribute light against the force exerted on the stencil printing machine.) Therefore, it is not possible to secure enough copies of IfiiJ for practical use.

If the heat shrinkage rate to satisfy /, g is extremely excessive, it will naturally be impossible to achieve the purpose of the present invention, but it is generally illusory, for example, as shown in Table 1 below. The one that shows the measured value of the heat shrinkage rate is used.

、格子状等部分的な塗布方法もとられる。AB - In the present invention, a base paper for heat-sensitive stencil printing is completed by laminating a polyethylene telescope film that satisfies each of the above requirements to a support. Although there are no limitations, when using an adhesive, it is necessary to use an adhesive that does not change in quality due to heating when perforating the polyester film, and to apply as little as possible. Depending on the case, partial coating methods such as mesh or grid pattern may also be used.

どおりの穿孔が１１量られる。Next, as a support, there is no shortage of materials that can change depending on the heat generated by the film when perforating the polynisdel film and that can transmit printing ink.Generally, thin paper, especially fine-mesh Shape paper is used. However, even if it does not meet the above conditions, it is also possible to use cloth, knitted fabric, mesh-like gauze, etc., which do not meet the above conditions. If the parts of the film that overlapped with the original's strokes were heated by closely stacking them and irradiating infrared rays from the support side, the number of perforations that corresponded to the characters and figures of the original would be 11. It will be done.
