とは、極めて困難であった。Heat-sensitive stencil printing base paper, which is made by adhesively laminating a plastic 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. Since this seed paper is perforated and printed by heating with a heat ray such as a xenon lamp or a thermal head, an adhesive that does not inhibit perforation and easily deforms at a relatively low temperature is used. On the other hand, printing machines using this type of base paper have also become more sophisticated and faster, and demands for the durability of the base paper have increased. In particular, strong organic solvents are often blended into the ink used, as strong print quality and quick drying properties are required, and this tends to weaken the adhesive strength of the adhesive, resulting in a reduction in the number of prints. In many cases, the printed characters often become deformed or blurred. In order to improve this solvent resistance, JP-A-61-116595 proposes a base paper using a specific urethane adhesive. According to this proposal, a base paper with good solvent resistance can be obtained, but in reality, if an attempt is made to sufficiently increase the solvent resistance with a urethane adhesive, the printing sensitivity will be considerably impaired. It has been extremely difficult to simultaneously obtain properties such as:

の溶剤はプラスチックフィルムを侵すことが多かった。Also, since urethane adhesives react with polar solvents such as alcohol, they are diluted with solvents that do not contain polar solvents such as ketones, esters, and aromatic hydrocarbons, but these solvents do not attack plastic films. There were many things.

のカールが著しかった。In particular, in the case of polyester films whose heat deformation temperature has been lowered by copolymerization or the like in order to improve thermal perforability, the sensitivity decreases and the laminate curls significantly due to contact with these solvents.

造方法に関するものである。The present invention provides a heat-sensitive stencil printing base paper in which an ink-permeable base material is laminated to a heat-shrinkable plastic film, and a solvent-resistant post-crosslinkable adhesive and a thermoplastic adhesive are used as the lamination adhesive. A heat-sensitive stencil printing base paper, a heat-shrinkable plastic film, and an ink-permeable base material are laminated using a solvent-resistant post-crosslinking adhesive, and then the ink-permeable base paper is laminated using a solvent-resistant post-crosslinking adhesive. The present invention relates to a method for producing a base paper for heat-sensitive stencil printing, which is characterized by infiltrating a thermoplastic adhesive from the side.

ド等の１０〜１ミクロンの薄い延伸フィルムである。The heat-shrinkable plastic film used in the present invention is a thin plastic film that is easily perforated by heating. Such films are disclosed in the above-mentioned JP-A-61-116595 and JP-A-59-16795.
A thin thermoplastic heat-shrinkable film such as that exemplified in Japanese Patent Application Publication No. 2003-100009 can be used. In particular, a film that has a relatively low melting temperature, high heat shrinkability, and whose melt viscosity easily decreases due to temperature rise is preferably used. Examples of suitable films are 10-1 micron thin stretched films of vinylidene chloride copolymers, polyesters, copolyesters, polyamides, copolyamides, and the like.

いられる。The ink-permeable base material used in the present invention is porous enough to allow the ink supplied from the ink-permeable base material side of the laminate to pass through well, and which has the main mechanical properties of the stencil paper. A material with sufficient mechanical strength can be used. Porous tissue paper, nonwoven fabric, gauze, etc. are used.

のアクリル系又はエポキシ系の接着剤等が用いられる。As the adhesive between the base material and the film, it is necessary to sequentially use a solvent-resistant post-crosslinkable adhesive and a thermoplastic adhesive. As the solvent-resistant post-crosslinkable adhesive, epoxy, urethane, light or electron beam crosslinkable acrylic or epoxy adhesives are used.

有する孔版原紙が得られることを見いだしたのである。All of these adhesives later undergo a crosslinking reaction to exhibit solvent resistance, but once solvent resistance appears, there is a tendency to reduce the sensitivity of perforation due to heat in the film, so they must be used in large quantities. It is not possible. Post-crosslinkable adhesives are
It is best to use as little amount as possible. If a post-crosslinkable adhesive is used in a small amount that does not significantly reduce the perforation sensitivity, the adhesion will be insufficient and the paper will easily peel off during handling, making it unusable as a stencil paper. However, we have discovered that by using a small amount of post-crosslinking adhesive and then bonding with a thermoplastic adhesive, a stencil paper with practically sufficient adhesive strength and perforation sensitivity can be obtained. be.

Polyacrylic acid ester, polyvinyl butyral, vinyl chloride, SBR, NBRl and others, saturated polyester,
A solution or emulsion of polyamide or the like is used. The method of laminating the film and the base material using an adhesive may be a dry lamination method, a wet lamination method, etc., but a particularly suitable method is the method described in Japanese Patent Publication No. 55-4.
As described in Japanese Patent No. 7997, a film and an ink-permeable base material are overlapped, and then an adhesive liquid is impregnated from the side of the ink-permeable base material to allow the adhesive to permeate the film surface and bond the film. It's a method. This method appears to produce an adhesive film of thermoplastic adhesive so as to effectively protect the outside of the crosslinkable adhesive joint.

と考えられる。[Function] Post-crosslinking adhesives must be applied in an amount greater than
It may flow and spread before crosslinking and hardening, making it difficult to develop adhesive strength. However, in the present invention, it is thought that an adhesive film of the thermoplastic adhesive is formed so as to protect the post-crosslinkable adhesive from the surroundings, and this protects the bonding points of the post-crosslinkable adhesive. It is believed that this creates a cross-linked and hardened junction. Furthermore, during printing, thermoplastic adhesives absorb the solvent in the ink and soften, resulting in a significant decrease in adhesive strength. However, in the case of the present invention, the solvent that has diffused from the emulsion ink is first absorbed into the thermoplastic adhesive. It is believed that it is effectively absorbed by the adhesive, distributed mainly in the thermoplastic adhesive layer, and serves to prevent the post-crosslinked adhesive from swelling and deteriorating.
