【発明の詳細な説明】 （産業上の利用分野） 本発明は感熱性孔版原紙に関し、特に熱可塑性合成樹脂
フィルムと多孔性支持体とからなる光照射により製版さ
れる感熱性孔版原紙に関する。Description: TECHNICAL FIELD The present invention relates to a heat-sensitive stencil sheet, and more particularly to a heat-sensitive stencil sheet which is made by light irradiation and comprises a thermoplastic synthetic resin film and a porous support.

性支持体のいずれかを着色する方法が知られている。(Prior Art) In a heat-sensitive stencil sheet made of a thermoplastic synthetic resin film and a porous support, which are used for conventional transcription printing and screen printing, the sensitivity of the heat-sensitive stencil sheet to light is improved, or the light irradiation time is increased. A method of coloring either a thermoplastic synthetic resin film or a porous support is known in order to reduce and improve the reproducibility of an image.

は、合成樹脂フィルムと多孔性支持体を貼り合わせる接
着剤の少なくとも１つを着色する方法が示されている。For example, Japanese Patent Publication No. 46-27509 discloses a method of coloring a synthetic resin film, and Japanese Patent Publication No. 54-33173 discloses a method of coloring at least one of a porous support or an adhesive for bonding a synthetic resin film and a porous support. It shows how to do it.
（発明が解決しようとする問題点） 上記従来技術において、着色された感熱性孔版原紙は、
着色されていない感熱性孔版原紙と比べて、3H位の薄い

得られる。(Problems to be Solved by the Invention) In the above-mentioned prior art, the colored heat-sensitive stencil sheet is
Compared to uncolored heat-sensitive stencil paper, images written with a thin pencil around 3H, images written by people with weak writing pressure, etc. are well perforated, which means that the heat-sensitive stencil paper has increased perforation sensitivity. However, when printed, excellent image reproducibility (resolution) is obtained.

射により原稿の画像部で発生した熱が着色された合成樹
脂フィルムに迅速に吸収され、合成樹脂フィルムが穿孔
されやすくなるためと考えられる。Although the reason for the increase in sensitivity has not been clarified yet, when the colorant of the colored heat-sensitive stencil base paper is irradiated with light, the colorant absorbs the light and generates heat, and the entire base paper is appropriately heated. It is considered that the synthetic resin film is easily perforated, or the heat generated in the image portion of the original by light irradiation is quickly absorbed by the colored synthetic resin film, and the synthetic resin film is easily perforated.

ため、着色されて穿孔感度が増大している上記の感熱性

を多発させてしまうためと考えられる。However, on the other hand, it has such an effect, but when you make and print a manuscript copied with a PPC type copier or a manuscript written with a relatively dark pencil, small black spots (pinholes) appear in places other than the image area. There was a problem that many occurred. The reason for this is that in these originals, there are many small dots (dirt) that are invisible to the toner and pencil powder in areas other than the image area, and are therefore colored to increase the perforation sensitivity. It is considered that these small dots are also perforated in the stencil sheet, and pinholes frequently occur.

It is to provide a heat-sensitive stencil sheet.

FIG. 6 is a schematic diagram showing a state in which a document being copied by a C copying machine is superimposed. The original 7 having the image area E is placed on the film side of the heat-sensitive stencil sheet in which the thermoplastic synthetic resin film is adhered to the porous support made from the uncolored fiber 3A and the colored fiber 3B. It is shown in the installed state. A large number of small dots (dirt) S of the document are seen around the image area E of the document 7. Fibers colored in colors other than white
In the heat-sensitive stencil sheet using the porous support containing 3B, since the colored fiber portion 3B is present, the film portion adjacent to that portion is easily perforated. On the other hand, since the invisible small dots (dirt) S of the document that cause pinholes are very small with respect to the image E, the probability of being close to or overlapping with the colored fiber portion 3B is much less than that of the image E. Become. In other words, since the image E is much larger than the small point S, the colored fiber will definitely cross this portion.
Since the small point S is small, the colored fiber hardly crosses it. As a result, the base paper portion in contact with the image E easily absorbs heat and the sensitivity is improved, while the small point S portion has the normal sensitivity and the occurrence of pinholes due to the increased sensitivity can be prevented. Further, in a manuscript written with a thin pencil, since there are many portions (colored portions) of the heat-sensitive stencil sheet that are easily perforated in the image area E, perforation is made in a sufficiently readable state. be able to.
