本発明はフィルムと各孔性薄葉紙をラミネートした孔版
印刷用原紙およびその製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stencil printing base paper in which a film and a porous thin paper are laminated together, and a method for producing the same.
従来より孔版印刷用原紙に関しては、種々のものが提案

のである。Various types of base paper for stencil printing have been proposed in the past, but the main ones are thin thermoplastic films (vinylidene chloride films, polyester films, polypropylene films, etc.) and porous thin paper (natural fiber 2 synthetic paper). Fibers, semi-synthetic fibers, and mixtures thereof) are laminated together. The principle is to overlap the original and the base paper, irradiate them with infrared rays, and utilize the difference in heat absorption between the image and non-image areas of the original, and only apply to the areas that correspond to the image areas with good heat absorption. It perforates the film. A copy identical to the original can be obtained by placing the base paper made in this way in a mimeograph machine and ejecting ink from the porous thin paper side.

捷しくないものである。したがって、ウェットラミネー
ト法で製造された原紙は、若干感度が劣る傾向にある。Now, several methods have been proposed for producing such base paper. A common method is a dry lamination method, and a special method is a wet lamination method (Japanese Patent Publication No. 55-47997). The Wenotramine 1 method involves combining a film 1 and a porous thin paper (hereinafter referred to as backing paper) 2 as shown in Figure 1, impregnating the backing paper with an adhesive 3, and drying it in an oven 4. This is a method for manufacturing base paper 5. In this method, since the fibers constituting the backing paper are wetted with the adhesive solution during adhesion, it is necessary to mix a certain amount of bast fibers into the paper so that the paper can maintain its strength even when wet. Bast fibers are thick, flat, and have poor transparency, so they inherently do not allow light to pass through, making them unsuitable for use as plate-making materials. Therefore, base paper manufactured by the wet lamination method tends to have slightly inferior sensitivity.

。In the dry lamination method, as shown in FIG. 2, an adhesive 7 is applied to a film 6, the film is twisted to an appropriate tack and dried in an oven 8, and then a backing paper 9 is adhered to form a base paper 10. This method has disadvantages in that it is difficult to adjust the size of a suitable tank, and that the adhesive strength is extremely weak and printing durability is poor.

ある。In order to solve the above-mentioned drawbacks, the present invention first adheres with a first adhesive using a dry lamination method, and then applies a second adhesive solution from the porous thin paper backing side to the impregnated interlayer film. After the dry lamination method, which dries at a temperature below the temperature change, the wet lamination method is used to bond again, thereby eliminating the weak adhesive strength that is a drawback of the dry lamination method, and eliminating the weak adhesive strength that is a drawback of the wet lamination method. This eliminates the need for mixing certain bast fibers.

が好捷しく、アクリル樹脂などでは、製版度が劣った。In this case, the first adhesive may have a slightly higher softening point because it is a relatively thin adhesive layer and is close to the film surface, that is, close to the original document which is a heat source. In addition to the most preferred vinyl acetate resin, acrylic resin is also possible. Vinyl acetate resin, which has a low softening point, is preferable for the second adhesive because it has the thickness of the paper and is far from the film surface, that is, from the original manuscript, which is the heat source. The degree was inferior.

ある。The second adhesive is preferably a water-dispersed vinyl acetate resin (using water as a solvent) so as not to swell or dissolve the first adhesive layer, but an alcohol-based solvent or the like may also be used.

The primary base paper that has been primarily bonded by the dry lamination method is impregnated from the backing paper side using the apparatus shown in FIG. In FIG. 3, a primary base paper 11 (corresponding to 10 in FIG. 2) is impregnated with a second adhesive 12, and dried in a furnace 13 at a temperature below which the film does not change, thereby producing a base paper 14. It is a device. Of course, it is also possible to integrate the devices of FIGS. 2 and 3 into one piece.

Note that when the base paper was not impregnated with the second adhesive, it did not have a printing durability of 100 sheets or less. Also, at the time of plate making, the original manuscript

When a base paper was manufactured using vinyl acetate (Bond 5P210 manufactured by Konishi) as a second adhesive base (aqueous solvent), the base paper swelled due to the second adhesive as described above. A base paper with the same performance as in the example was obtained.Furthermore, as the first adhesive, Nippon Zeon's acrylic copolymer (〕・〕acrylic acid) was dissolved in a mixed solvent of methyl ethyl ketone and ethyl acetate, and the second adhesive was used as the first adhesive. When a base paper was manufactured using the above-mentioned polyvinyl acetate 88110 as an adhesive, a base paper having similar performance was obtained.
