簡便に製版される利点を備えている。Background of the Invention As one of the base papers for stencil printing, a thermoplastic synthetic resin film such as a polyester film or other synthetic resin film and a porous ink-permeable sheet adhered to one surface of the synthetic resin film are used. Heat-sensitive stencil printing paper made of a polymer with a support is known, and this type of stencil printing paper has a component such as carbon black that absorbs heat and generates heat on the other side of the synthetic resin film. original sheets having an image portion containing the image portion are superimposed with the image surface thereof being a bonding surface with the synthetic resin film,
The synthetic resin film is melted or changed by the heat generated in the image area of the original sheet by irradiating the porous support with light, especially light rays containing a large amount of infrared radiation, from the side of the porous support while in close contact with the original sheet. A perforated image having a shape corresponding to the shape of the original image is produced on the synthetic resin film, and the heat-sensitive stencil printing base paper has the advantage that it can be easily plated by a heat-sensitive copying method.

である。 The sheet-like porous support adhered to one side of the synthetic resin film of the base paper for heat-sensitive stencil printing is
This is essential for reinforcing the synthetic resin film and preventing the inner part of the perforated image with a closed loop part, such as the letters O and P, formed on the synthetic resin film from falling off, and for heat-sensitive stencil printing. When a polymer of a base paper and a manuscript sheet is sandwiched between a light-transmitting plate called a stage glass and a pressure plate and plate-made by light irradiation, the manuscript is placed between a synthetic resin film and a stage glass. A heat insulating layer is formed to prevent the heat generated in the image area of the sheet from dissipating to the stage glass, and the heat generated in the image area is effectively transmitted to the synthetic resin film to form a perforated image. Contributing and useful.

える。 Conventionally, porous supports used in the above-mentioned type of heat-sensitive stencil printing base paper include Japanese paper,
Nonwoven fabrics, woven fabrics (screen mesh), etc. are used, and these porous supports form a heat insulating layer as described above and effectively contribute to the formation of perforated images, but at the same time, they are used for plate making. In particular, when the porous support is Japanese paper or nonwoven fabric, the thickness of the fibers, the size, shape, and distribution of the porous openings are uneven, and the fibers are spread in the thickness direction. Because there are many irregularly overlapping parts,
The light transmittance is non-uniform and low, which is not desirable for forming a perforated image faithful to the original image on the synthetic resin film. In addition, the porous support as described above obstructs the passage of printing ink during printing, causing blurring of the printed image, which has an undesirable effect on obtaining a high-quality printed image.

ている。 The base paper for heat-sensitive stencil printing using a porous support made of woven fabric is characterized by the thickness of the fibers of the porous support,
The size, shape and distribution of the porous openings are uniform, and the fibers do not overlap irregularly in the thickness direction, so it is suitable for heat-sensitive stencil printing including porous supports made of Japanese paper or non-woven fabric. Compared to base paper, the light transmittance is uniform and high, and a good perforated image can be formed. Moreover, it has high resolution, and can form a delicate and clear printed image with less blurring.
However, the woven fabric for the porous support used in heat-sensitive stencil printing base paper generally has a fiber diameter of 0.01
Since it is produced by spinning thin fibers of ~0.1 mm into a relatively high mesh, the production cost is high. It is more popular than heat-sensitive stencil printing base paper made of Japanese paper or non-woven fabric.

用原紙のコストを高謄させることがない。Effects of the Invention In the heat-sensitive stencil printing base paper constructed as described above, a striped support is formed on one side of the synthetic resin film by a large number of fibers arranged in only one direction, and the support The body has no overlapping fibers at all and has regular slit-like openings between the fibers, compared to a woven fabric support that has lattice-like openings between the fibers. The transmittance of light rays during plate making and the transmittance of printing ink during printing are higher and more uniform, and as a result, this base paper forms perforated images that are faithful to the original image and has high resolution. It is possible to form high-quality printed images with excellent properties and no blurring. The support of the heat-sensitive stencil printing base paper according to the present invention has only fibers arranged in one direction, and the inner part of the perforated image having a closed loop part is formed by appropriately determining the spacing between the fibers. to effectively prevent it from falling off. Since this support is composed of fibers arranged in stripes in only one direction, there is no need for spinning, and since the fibers are arranged in stripes in only one direction, it can be easily produced. It has better properties than screen mesh, and does not increase the cost of stencil printing base paper.

紙は必要最少限の強度を備える。 Since the heat-sensitive stencil printing base paper according to the present invention has continuous fibers in only one direction, the tensile strength in the direction perpendicular to the extending direction of the fibers is lower than that in the extending direction. , the direction of action of the tensile force acting on the stencil printing base paper during printing is the printing direction, for example, when the stencil printing base paper is wound around the plate cylinder of a rotary printing press, it is mainly applied in the circumferential direction of the plate cylinder. Therefore, the tensile strength actually required for stencil printing base paper is only in one direction, and therefore, the direction in which the fibers extend can be adjusted as appropriate depending on the conditions of use during printing of stencil printing base paper. By selecting this, the heat-sensitive stencil printing base paper of the present invention has the minimum necessary strength.

補強がなされる。 In the heat-sensitive stencil printing base paper of the present invention, if the synthetic resin film has a property of melting under heat like a thermoplastic synthetic resin film, the perforated image corresponding to the original image formed by melting A bridge is formed by the melted residue of the synthetic resin film between adjacent fibers, which partially connects the two fibers, which prevents the fibers from moving laterally in the perforated image, and also prevents the fibers from moving in the perforated image. The fibers are reinforced by entangling the molten residue of the synthetic resin film.

The polymer with the original sheet 5 arranged with the image surface joined to the side is placed between the stage glass and the pressure plate 7, with the heat-sensitive stencil printing base paper 1 facing the stage glass 6. This is carried out by sandwiching and pressing the polymer, and in this pressed state, a light beam containing a large amount of infrared radiation is irradiated toward the polymer from the stage glass 6 side. When the polymer is irradiated with a light beam 8 containing a large amount of infrared radiation, a larger amount of light energy is absorbed in the image area 5a of the original sheet 5 than in other parts, and this instantaneously changes into thermal energy. Then, the image section 5a starts to generate heat.

る。 Synthetic resin film 2 of heat-sensitive stencil printing base paper 1
Since the support is only the fibers 3 arranged in stripes, the transmittance of the light rays 8 through the heat-sensitive stencil printing base paper 1 is extremely high, and therefore a relatively large amount of light rays is transmitted to the image area 5a of the original sheet 5. irradiation, so that sufficient heat is generated in the image area necessary to melt the synthetic resin film 2 or to perforate it by other thermal effects. As the heat generated by the image area 5a is transmitted to the synthetic resin film 2 that is in close contact with the image area 5a, the portion of the synthetic resin film 2 that is in close contact with the image area 5a is melted or perforated due to thermal influence, and the third As shown in the enlarged figure, the thermoplastic synthetic resin film 2 is covered with an original image area 5.
A perforation image 9 having a shape corresponding to the shape of a is formed.

行われる。 As clearly shown in FIG. 2, the fibers 3 form a heat insulating air layer 10 between the synthetic resin film 2 of the heat-sensitive stencil printing paper 1 and the stage glass 6 during plate making. This heat insulating air layer 10 prevents the heat transferred from the image area 5a of the original sheet 5 to the synthetic resin film 2 from being transferred to the stage glass 6 and dissipating, thereby performing thermal plate making with high energy efficiency.

る。 When the distance between the adjacent fibers 3 becomes large, the synthetic resin film 2 comes into direct contact with the stage glass 6 between the fibers, so the distance between the adjacent fibers is set with this point in mind. It is preferable that the pressure plate 7 is made of a material such as the material of the pressure plate 7, the material of the document sheet 5, etc.

好ましくは0.5mm以下であつてよい。 If the synthetic resin film 2 is a thermoplastic material that melts under heat, the perforated image 9 of the synthetic resin film 2, as shown in FIGS. The melted residue 11 of the film 2 is entangled with the fibers 3, and the melted residue forms bridges 12 between the adjacent fibers 3, partially connecting them to each other. This bridge 12
This ensures mechanical strength in the direction perpendicular to the extending direction of the fibers 3 in the perforated image 9 of the heat-sensitive stencil printing base paper 1. Bridges 12 caused by the melted residue 11 of the synthetic resin film 2 become more difficult to form as the distance between adjacent fibers increases.In order for this bridge to be effectively formed, the distance between adjacent fibers must be Although it varies depending on the material and the film thickness, it is preferably 0.5 mm or less. Therefore, in order to meet all the requirements mentioned above, the spacing between adjacent fibers may more preferably be 0.5 mm or less.
