Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention enables direct printing by a printer using a thermal printer such as a word processor, and can be used to print a simple printing machine such as a hobby printing machine. The present invention relates to a heat-sensitive stencil original plate that can be attached to a printer (for example, a printout manufactured by Riso Kagaku Kogyo Co., Ltd., hereinafter referred to as a simple printing machine) and can print about several hundred sheets.

<Prior Art> Recently, simple printing of about 100 sheets, such as New Year's cards, has been carried out using heat-sensitive stencil paper made of a combination of a porous sheet and a thermoplastic resin film. In this case, the following method was used to create the manuscript using a word processor. In other words, you can print out the edited version from a word processor and then use it directly as a manuscript, or you can retake the edited version using RPC and use it as a manuscript, and then place a stencil on top of the original. Flash plate making was performed from above using a bulb flash or the like. Another method is to directly print out postcards one by one using a word processing sensor. However, such methods require various troublesome efforts and time, and
It also costs money. There was a problem.

<Problems to be Solved by the Invention> According to the conventional technology, there is no suitable original plate that can be printed directly by a printer such as a word processor and immediately printed by attaching it to a simple printing machine, and the appearance of one is desired. was.

The present invention aims to solve such problems.

Means for Solving the Problems> The present invention addresses the above-mentioned circumstances! As a result of careful consideration,
By attaching a flexible reinforcing base material to the thermal stencil paper and applying it to a word processor for printing,
A printing original plate is obtained, and one side of an ink-impermeable sheet is adhered to one side of a flexible reinforcing base material in advance to create an original plate that can be directly printed on. flexibility supplement.

It has been found that it is possible to easily print about 100 sheets by cutting out only the printing area of the strong base material and using a simple printing machine.

The specific outline of the thermal stencil original plate of the present invention is as follows.

A flexible heat-sensitive stencil base paper in which at least an adhesive layer and a thermoplastic resin film layer are sequentially provided on one side of the porous sheet, and cuts are provided on the other side of the porous sheet to cut out the printing area. This is a heat-sensitive stencil original formed by adhering a frame portion of a reinforcing base material and adhering one side of an ink-impermeable sheet to at least one side of the frame portion of the reinforcing base material. If the thermoplastic resin film layer has a material with mold releasability such as a fluororesin or silicone resin, it is left as is, but if it is not, a stick prevention layer is separately provided on its surface.

Next, as a flexible reinforcing base material, the thickness is 50 to 600μ,
Stiffness 3~l 50gf-cs (However, JIS P8
Paperboard stiffness test method by 125 load bending method), plastic film, and plastic foam sheet are applicable.

As the porous sheet of the heat-sensitive stencil paper used here, paper, non-woven fabric, or woven fabric made mainly from natural fibers such as mitsumata, kozo, Manila hemp, and synthetic fibers such as rayon, polyvinyl alcohol, and polyester are used. .

The adhesive layer is not particularly limited, but suitable materials such as polyester resin, polyvinyl acetate resin, polyvinyl chloride resin, polyacrylic resin, etc. can be used. Of course, it is not limited to this.

Examples of the thermoplastic resin film layer include the following.

Homopolymers, copolymers, and blends of polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, polyvinyl acetal, polystyrene, polycarbonate, polyester, polyamide cellulose acetate, ethyl cellulose, acrylic resin, fluororesin, silicone resin, etc.

Examples of ink-impermeable sheets include plastic sheets that are incompatible with ink, such as polyester, fluororesin, silicone resin, vinylidene chloride resin sheets, and paper;
Processed paper, metal foil, woven fabric, etc. are appropriately selected and used.

The present invention will be described below with reference to the drawings. As seen in the cross-sectional view of FIG.
A thermoplastic resin film layer 3 and an optional stick prevention layer 4 are sequentially provided to constitute a thermosensitive stencil paper A.

As shown in FIG. 2, the flexible reinforcing base material B has a cut 5 between the frame portion 6 and the printing area 7, and the other side of the porous sheet of the heat-sensitive stencil paper A and the frame portion. They are glued together and integrated.

Next, the ink-impermeable sheet C is stacked on the flexible reinforcing base material B, and at least one side of the center of each frame is adhered.

The adhesive area is determined by the machine that attaches the original plate, but if you want to have more variety, you can use ethylene vinyl acetate hot melt adhesive or PVC adhesive on the two sides (frame part) that form the rectangle of the original plate. If you use double-sided adhesive tape on two sides and make it removable, you can attach it to a simple printing machine whether it is a vertical type or a horizontal type, and it is versatile. This is advantageous.

To specifically explain the steps of plate making and printing using the original plate of the present invention, first, printing is performed using a word processor, and then the printing area of the flexible reinforcing base material is cut and removed from the cut line, and then printed on a simple printing machine. , it is possible to print several hundred sheets easily and clearly. Note that the cuts in the flexible reinforcing base material may all be made with the same perforations, but the efficiency of the removal work in the printing area may be improved by making large cutting lines at some corners or complete cutting lines at the negative sides. can be increased.

<Example> Examples will be described below.

Example 1 Polyester film (
A saturated polyester resin (Vylon 200. manufactured by Toyobo Co., Ltd.) was used as an adhesive. Isocyanate (curing agent)
] using a wire bar (0,3n+φ) to form an adhesive layer so that the coating amount is 1.0 gird,
Manila magi (basis weight 11g) is made from this into a porous sheet.
/rrr, thickness 40μll1) by the s7 laminate method.

Next, a room temperature curing silicone resin [Toray Silicone PRX 305 (base resin), Toray Silicone SH23K (curing agent) manufactured by Toray Silicone Co., Ltd.] was applied as a stick prevention layer on the polyester film in a coating amount of 0.05 g/
A base paper for heat-sensitive stenciling was prepared by coating and drying the mixture to give a RD.

On the other hand, card paper with a thickness of 180 μm and a stiffness of 23 gf-cm is used as a flexible reinforcing base material, and cuts (perforations) are provided at the border between the frame portion and the printable area, and these are used for the heat-sensitive stencil plate. The base paper and frame are fully laminated and reinforced.

Next, layer a 20 μm thick polyester film (ink-impermeable sheet) on this card paper, and
The sides were adhered to obtain a heat-sensitive stencil original plate of the present invention.

If you use this to print with a word processor, there will be no steps and you can easily attach it to the machine and print.Next, the printable area of the flexible reinforcing base material is cut away from the perforations and printed on the porous sheet. I was able to expose the part, attach it to a simple printing machine (if the attachment is loose, use an appropriate piece of cardboard as a cutter), and print easily. For example, when printing was performed using Print Gocco manufactured by Riso Kagaku Kogyo Co., Ltd., it was possible to print 100 clear prints that were faithful to the original.

Example 2 A porous sheet made of polyester fiber (basis weight 12 g) was coated with 1.0 g of saturated polyester resin [Vylon 200 manufactured by Toyobo Co., Ltd. Isocyanate (curing agent)] as an adhesive. /rd so that
A heat-sensitive stencil original plate of the present invention was obtained in the same manner as in Example 1 except that an adhesive layer was formed by coating using a wire bar (0.3 tmφ).

Using this, printing was carried out using a word processor in the same manner as in Example 1, and then 100 sheets were printed using a simple printing machine. As in Example 1, it was possible to obtain clear printed matter that was faithful to the original □.

<Effects of the Invention> According to the present invention, since the flexible reinforcing base material is stacked and integrated with the porous sheet, printing by a word processor can be easily performed, and furthermore, the printing area of this base material can be printed immediately before printing. Since it can be cut out and printed, it is simple and inexpensive, and moreover, it is possible to print about several hundred sheets clearly.
