2. Description of the Related Art Conventional posters, stickers, labels,
When sticking a sticking material such as a display board or a light-shielding film to an adherend such as a bulletin board or window glass, apply a strong adhesive to the place where the product is to be stuck, or stick it, Alternatively, it is well known how to bond products to which a sticky adhesive has been applied beforehand, and conventional products were not interested in peeling after use, so peel those products after use. In some cases, after removal, the trace of gluing of an adhesive or the like remains on the sticking surface of the adherend, and peeling is difficult, which may damage the adherend. Further, it was almost impossible to reuse the patch after peeling.

[0003]

As a use different from the conventional purpose, a poster made of a sheet or film made of a material such as vinyl chloride or synthetic paper,
Adhesive products such as stickers, labels, light-shielding films, etc. can be adhered to an adherend such as a bulletin board or window glass without using an adhesive, and can be easily peeled off from the adherend when used, and the sticking The purpose is to enable the wood product to be reused repeatedly.

[0004]

[Means for Solving the Problems] As a method therefor, an adhesive agent or the like is provided by providing a fine mesh-shaped suction cup layer (4) on the entire attaching surface (2) to which the adhesive material (1) such as a sheet or film is attached. It is possible to hold the adhesive material (1) such as a sheet or film on an adherend (8) such as a bulletin board such as a glass plate, an iron plate, a plastic board or the like, without using. On the back surface (2), which is the surface to which the adhesive material (1) such as a sheet or film of soft or hard polyvinyl chloride or synthetic paper is attached, dissolve the polyvinyl chloride resin in a mixed solution and apply a plasticizer, etc. The ink-like substance (3) that has been made flexible and flexible by printing is printed with a fine mesh-like sucker type continuous pattern (4) by a screen printing method, and the back surface of the patch (1) ( The problem can be solved by a method of installing the suction cup layer (9) on the whole of 2).

[0005]

ACTION 1 As claimed in claim 1, polychlorinated as a material for the suction cup layer (9) installed on the back surface (2) of the transparent or opaque vinyl chloride resin or synthetic paper, which is the adhesive surface of (1). Flexibility and flexibility by adding a plasticizer (10) such as dioctyl phthalate to a substance obtained by dissolving a vinyl resin (13) using a mixed solvent (14) such as ethyl acetate, methyl ethyl ketone, etc. The ink-like substance (3), which is used as a sucker material by adjusting the degree, is printed with a mesh-like sucker-shaped continuous pattern (4) by a method such as screen printing using the ink-like substance (3) and dried. By providing the fixed sucker layer (9), the sheet (5) with a sucker is manufactured.

[0006]

In the second aspect, when a sheet or film of polyolefin resin such as polyethylene resin or polypropylene resin or polyester resin is used as the patch (11), polyvinyl chloride resin is used as the base material. Since the ink-like substance (3) which is a sucker material is difficult to be fixed, the adhesive material (1) used as a pre-process for fixing and printing the sucker material which is the ink-like substance (3)
Ink or paint (6) made of a component suitable for the material of 1), for example, epoxy resin, urethane resin or sulfide rubber, is printed or applied on the entire surface (12) on which the suction cup layer (9) is to be printed. An adhesive layer (7) of suction cup material is provided and dried and fixed.

[0007]

[Function 3] The above polyvinyl chloride resin (13) is used as a material for the suction cup on the adhesive layer (7) of the suction cup material printed by the above-mentioned process
An ink-like substance (3) that becomes a sucker material by adjusting the flexibility and flexibility by adding and blending a plasticizer (10) such as dioctyl phthalate to a substance dissolved in a mixed solvent (14) such as ketone Using the ink-like substance (3) as the sucker material, a mesh-like sucker-shaped continuous pattern (4) is printed by a method such as screen printing, dried and fixed, and the sucker layer (9) is installed. By this, a sheet with a suction cup (5)
Is manufactured.

[0008]

[Embodiment 1] As an embodiment of claim 1, a transparent or colored soft vinyl chloride sheet (1) having a thickness of about 0.3 mm or the like is printed with a suction layer (9) on the back surface (2). PVC material (13)
Is adjusted to the state (3) of the printing ink with a mixed solvent (14) of ethyl acetate, methyl-ethyl-ketone or the like. The ink-like substance (3) serving as the sucker material is made of polyvinyl chloride as a base material, for example, a screen ink "SS7GK type medium" manufactured by Toyo Ink Mfg. Co., Ltd. or "LO" manufactured by Seiko Co., Ltd.
V type medium "or" VS, XG medium "manufactured by Teikoku Ink Mfg. Co., Ltd. can be mixed and used. Sucker material (3) with the above-mentioned ink as it is
Since it is not suitable for a sucker because the hardness is high when the ink is dried and fixed, a plasticizer such as dioctyl phthalate or tricresyl phosphate (1
It is necessary to add 0) appropriately to give flexible flexibility, so it is appropriate to add about 20 to 50% of the plasticizer (10) such as dioctyl phthalate to the above ink 100. is there. The mixing ratio of the plasticizer is the mixing ratio of the solvent contained in the ink, the size and weight of the patch (1), and the type and thickness of the continuous pattern (4) printed on the suction cup type.
It is determined by considering the degree of flexibility depending on the conditions such as shape and adhesive strength, but when newly manufacturing the ink-like substance (3) which will be a dedicated suction cup material, the compounding ratio of the solvent can be reduced. The compounding ratio of the plasticizer (10) can also be reduced.

A screen printing method is suitable as a method for printing the ink or the like (3) which is the above-mentioned sucker material.
As a condition of the sucker layer (9) to be printed, the larger the volume of the hollow chamber inside the single sucker, the higher the degree of vacuum when pressure-bonded or the degree of adhesion when depressurized, and thus the meat of the sucker material to be printed. It is a good condition that the height is as thick as possible. As the plate (15) used for screen printing, it is appropriate to use a very thick plate (16) for making plate of about 70 to 150 mesh per inch, and in the plate making by the direct plate making method, the back surface (17) of the plate is used. ) Is usually applied to about 10 μm.
It is desirable to increase the thickness of 8) to about 20 to 50 μm. If necessary, if a plate-making photosensitive sol film (18) is also provided on the surface (19), which is the scraping surface of the squeegee of the screen plate, to increase the plate thickness, the thickness of the sucker to be printed increases and the suction force is increased. Good conditions can be obtained.
Further, when the carbon tissue (20) is used for the plate making of the screen printing plate by the indirect plate making method, a good result can be expected because the carbon tissue film is thicker than the photosensitive sol film of the direct plate making method.

The shape of the sucker material printed by the above-mentioned method, the continuous pattern, etc. (4) are different in size shape and continuous pattern depending on the purpose of use, but the basic shape is a mesh shape such as a circle or an ellipse. Is the basic shape, but as an example of another special continuous pattern, a honeycomb shape such as a donut shape or a hexagonal shape is effective.

[0011]

Example 2 As an example of claim 2, polyethylene,
Polyolefin resin such as polypropylene, polyamide resin such as nylon, or polyethylene terephthalate resin such as polyester, such as a film or sheet (1
In 1), the adhesion and fixing conditions are not suitable for the polyvinyl chloride resin, which is the material for the suction cup, so the ink (6) suitable for each material and a method such as surface treatment should be applied to cover the entire surface of the suction cup. It is necessary to install the adhesive layer (7) of the suction cup material by printing or applying the adhesive layer (7) of (1) by a method such as printing or coating. Polyolefin or polypropylene film or sheet is surface treated by corona discharge or gas flame method and printed with epoxy resin ink, or pretreatment is omitted and sulfurized rubber ink is used. At (6), printing is performed and drying and fixing is performed. In this case, when the former surface treatment is performed, "SS17 manufactured by Toyo Ink Mfg. Co., Ltd.
Ink such as "-000 series, medium" or "POS, PRO" manufactured by Teikoku Ink Mfg. Co., Ltd. is suitable. In the case of omitting the latter pretreatment, "SSPPNK medium" manufactured by Toyo Ink Mfg. Co., Ltd.
Alternatively, the use of "PPG" manufactured by Teikoku Ink Mfg. Co., Ltd. is suitable, but it is unavoidable that the adhesive strength is slightly inferior to the former method.

Further, as an ink suitable for printing on a polyethylene terephthalate resin film or sheet such as polyester, "SS60-000 series, medium" manufactured by Toyo Ink Mfg. Co., Ltd., Teikoku Ink Mfg. Co., Ltd. "EG type, medium" or the like is suitable.

The sucker layer (9) is screen-printed by the method described in the above [claim 1] on the surface on which the adhesive layer (7) to which the sucker material is adhered in the previous step is fixed. The sheet with a suction cup (5) provided with is manufactured.

The sheet with a suction cup (5) produced by the above-mentioned method is used for a poster, a sticker, a display board, etc., by subjecting the surface to an appropriate display printing (21). In addition, if necessary, before the printing and fixing of the suction cup layer (9), an appropriate thin-walled display printing (21) is performed and the suction cup layer (9) is placed on the display print (21), so that it can be used for building window glass and automobiles. By sticking a sticker or a light-shielding film or other sticking material on the inside of the window glass, you can see the printed characters (21) printed on the sticker from the outside (21), and also on the transparent film or sheet from the surface. Similar effects can be obtained by printing and viewing from the adhesive surface on the back side.
