Description

The present invention is a so-called back-attached display object in which a sheet display object is attached to the back surface of a transparent window glass such as a store, a transparent window glass of a car, a transparent resin plate, etc., illuminated with a fluorescent lamp from the back side, and the display object is viewed from the front side. The present invention relates to a back-coated micro sucker display that can be repeatedly applied and peeled off by printing an image on a micro sucker with an ultraviolet curable ink jet printer and leaving at least a residual portion that is not output printed.

Conventionally, display materials such as advertising posters are mostly used on the surface of adherends, so-called front display materials, but transparent window glass is used to avoid rain or wind and prevent it from being intentionally removed. There are many display objects that are backed with an adhesive on the inside and viewed from outside the window glass. In this case, the display is attached so that it adheres to the glass as much as possible, but there is a gap between the glass and the display, and it becomes a lining display with a loss of aesthetics when viewed from the outside of the window glass. End up.

For display objects lined on the window glass, a back-sticking adhesive display object, which is shown with a fluorescent lamp from the back side, is often used. However, the biggest drawback is that when pasted on a window glass, if the display area becomes large, bubbles will be mixed and wrinkles will not be applied cleanly. If a fluorescent lamp is applied from the back side, the bubbles will be mixed with wrinkles. There is a difficulty that it is raised and cannot be used as a backed display for lighting. If you can peel off the backed display using an adhesive, you may want to remove it and reposition it or reuse it.However, the adhesive will stick, the glue will remain, and there will be a lot of dust. Currently, it cannot be used or stored. In this way, the disadvantage of the back-sided adhesive display with the adhesive applied to the printed surface of the display is that when it is attached to the window glass, a large number of air bubbles are mixed between the window glass and the adhesive surface, resulting in a large number on the surface. It appears as a convex bulge, and there is a difficulty that amateurs can not stick beautifully. Also, once the poster is affixed, the adhesive remains on the glass surface. To remove it, it must be removed using toluene, thinner, gasoline, etc., which requires a lot of work.

In the present invention, a foamed acrylate copolymer emulsion is coated on one side of the backing of the backing display object to form a micro sucker, and output printing is performed on the micro sucker with an ultraviolet curable ink jet printer. The present invention relates to a back-coated micro sucker display that can be attached and peeled off by leaving at least a remaining portion that is not output printed, and can easily deaerate air bubbles that have been embraced at the time of application. As a method for solving these drawbacks, Patent Document 1 discloses that a water-based inkjet receiving layer is locally formed on a micro sucker formed by applying and drying a foamed acrylic ester polymer emulsion, and water is applied only to this portion. A method is disclosed in which a water-based ink is landed by an ink jet printer, and is attached to a window glass or the like by the adsorption force of a micro sucker in another portion where the water-based ink receiving layer is not applied. This method has the inconvenience that only the portion provided with the water-based ink receiving layer can be printed. In Patent Document 1, an image is once formed on a transfer paper by an electronic copying machine, the image is thermally transferred onto the surface of the micro sucker layer, and the backing is applied by the suction force of the micro sucker in a portion where the image is not transferred. A method of enabling is also disclosed. However, the toner image surface output by the electronic copying machine is naturally attached to the back surface and brought into close contact with the glass surface. However, after 3 months of close contact, the toner is transferred to the glass surface and is removed with a solvent. It can only be removed with a difficult task. The present invention uses a UV curable inkjet printer to output print on a micro sucker formed by coating and drying a foamed acrylate polymer emulsion on a support, and the output printing surface is a window glass or transparent resin plate It is related with the backing micro sucker display thing which is stuck on and peeled off repeatedly, and does not embrace bubbles at the time of pasting construction.

The development of inkjet printers has been remarkable over the past decade, starting with water-based inkjet printers that land on water-based inks, followed by solvent inkjet printers that land on solvent inks, and see the emergence of UV-curable inkjet printers three years ago. At the same time, the development of the media applied to each of them further expands its uses. Many patents have been filed as media for micro-suction cups. The feature of UV curable inkjet printers is the use of UV curable ink that instantly dries with UV, eliminating the need for thermal drying required for water-based inks and solvent inks, greatly reducing the work time from printing to processing. it can. In addition, the ultraviolet curable ink landed on the medium does not release the organic solvent, and the landed ink immediately cures 100%, enabling output printing with a buildup of 10 μm to 15 μm. When output printing is performed on the micro sucker, as shown in FIG. 4, the surface of the micro sucker rises 10 μ to 15 μ, and the adsorbing power of the micro sucker portion that is output and printed by the air entering from the raised gap disappears. Furthermore, since the raised ink has come out on the surface, it does not become a light print like water-based ink and solvent ink, but becomes a vivid printed matter. The UV curable inkjet printer media can be used for output printing not only on thin sheet-like supports such as paper and resin films, but also on plate-like supports having a thickness of about 10 mm.

The support 3 is a base material to which the micro suction cup 4 is bonded, and it may not necessarily be a transparent resin film, but may be translucent or opaque as long as it is not a display for electrical decoration. Select according to the purpose. The resin film preferably has a thickness of 500 μm or less in the present invention. Polyester film, PVC film, acrylic film, polypropylene film, polyethylene film, urethane film, and polycarbonate film are preferable. Among them, for a polyester film, a thick 75 to 200 μm transparent and easily adhesive polyester film (Toyobo A4300) having a high adsorbing power with a micro suction cup is preferable. For the PVC film, a soft film (Bandow Chemical WY02018) having a thickness of 80 to 150 μ containing 8 to 35 parts of a plasticizer is preferable. In the case of paper, it may be coated paper having a thickness of 80 μm to 150 μm, kraft paper, high-quality paper, kraft paper, or non-woven fabric that has been single-sided polylaminated. The resin plate may be transparent or opaque other than the display for electrical decoration. The thickness is preferably a foamed polystyrene plate, a vinyl chloride plate, a polypropylene plate, a polyethylene plate, or an acrylic plate having a thickness of 10 mm or less.

Although the micro sucker 4 is disclosed in Patent Document 6, the foaming agent, the thickener, the foaming agent, the curing agent, the pigment, and the plasticizer are added to the acrylic ester copolymer emulsion liquid in a certain ratio. After mixing, compressed air was fed through a mechanical foaming machine “Oaks mixer”, and the foaming ratio was 1.2 to 5 times (the weight per unit volume before foaming was divided by the weight per unit volume after foaming). (Numerical value) refers to a foamed sheet having a thickness of 50 μm to 1000 μm formed by applying a foamed acrylic emulsion liquid containing countless fine bubbles to the support 2 with a comma coater and drying. The micro sucker is an adsorbent foam sheet having a structure in which internal bubbles having a diameter larger than the diameter of the micro sucker are continuous with other bubbles by a small diameter tube. The micro-suction cup after application has innumerable fine concave depression holes but is not necessarily a perfect circle. The major diameter of the concave depression hole 19 is 300 microns or less, and the average number of concave depression holes of 30 μm to 100 μm is 95. % And 1 to 100,000 pieces / cm ² are formed per unit area. This fine and flexible concave recessed hole 19 exhibits negative pressure adsorption force, and as disclosed in Patent Document 6, by adding a plasticizer to the acrylate copolymer emulsion liquid, a smooth surface as well as certain unevenness is obtained. It comes to give the function of adsorbing well on the surface and repeatedly sticking and peeling. The negative pressure adsorption force is a suction force that is generated when the recessed depression hole and the adherend surface are pressed against each other and the sealed space formed by the concave depression hole and the adherend surface is in a reduced pressure state. On the other hand, when it is attached to an adherend such as the window glass 17, bubbles are embraced between the adherend and the micro sucker, but the embraced bubbles are absorbed by the concave depression holes 19 of the micro sucker 4 and disappear. This phenomenon is called deaeration, which is a characteristic of micro suckers. The surface of the micro sucker is transported while being in contact with two or three guide rolls in the output printing of the ink jet printer. However, the micro sucker is not sticky and therefore does not get caught in the guide roll and is smooth. It has the characteristic that it is conveyed. Needless to say, smooth transfer is not possible with an adhesive. The micro sucker is an adhesion mechanism generated by the negative pressure adsorption force exerted by the fine concave depression hole, and has a function of repeatedly sticking and peeling, which is difficult with an adhesive.
A micro suction cup having a foaming ratio of 1.2 times to 5 times is a foamed sheet. When light is applied from the back side, a concave depression hole of 30 μm to 100 μm diffuses light and becomes translucent. This brings about the effect as an electric display object.

Patent Literature 2, Patent Literature 3, and Patent Literature 4 report a method for creating a back-side display object that is produced by direct output printing on a micro suction cup using an inkjet printer for water-based ink or an inkjet printer for solvent ink. ing. However, as shown in Japanese Patent Application Laid-Open No. 2003-28400, the back-displayed display printed by this method is not printed on the surface because the printing ink is landed and sucked into the recessed hole on the surface of the micro-suction cup. It becomes printing. In addition, the water-based ink and the solvent ink are inevitably poor in drying properties and maintain fluidity immediately after output printing. When the ink is wound around the take-up roll 21 in the printer immediately after output printing, the undried ink is supported as shown in FIG. The other surface is transferred and contaminated, resulting in a defective product. Moreover, when many output prints are stacked, the undried ink is transferred to the other surface of the support and becomes a defective product. As a countermeasure, Patent Document 3 discloses a method for coating a transparent resin film on a micro sucker surface after printing. However, in this method, the coating of the micro sucker is not easy and the cost is high.

Further, as described in Patent Document 3, if the water-based ink and the solvent ink landed in the concave depression hole 19 of the micro suction cup are undried, the water-based ink and the solvent ink are applied to the window glass 17 or the transparent acrylic plate 17 that has been back-coated. Partially contaminates the window glass after it is peeled off. In particular, when backing is applied to a transparent acrylic plate, undried ink is transferred to the transparent acrylic plate in one week and cannot be used repeatedly. Needless to say, it is difficult to remove the transfer-contaminated ink. Patent Document 2 reports a method for producing a backing display by thermocompression bonding of a sheet printed with sublimation ink to a micro suction cup. This method has the advantage that the sublimation ink does not transfer and become contaminated on the window glass or transparent acrylic plate, but the image printed on the surface of the micro-suction cup after 3 months is pasted. It has the disadvantage that the outline is blurred and does not become a product.

Problems to be solved by the invention

As described above, (1) water-based ink or solvent ink landed in the concave depression hole of the micro suction cup with a water-based or solvent ink jet printer has a low printing density and falls into merchandise. (2) The printing ink output on the micro suction cup is When it is lined, it becomes difficult to remove it because it is transferred to window glass or a transparent acrylic plate, making it difficult to remove. (3) The output printed matter of an aqueous or solvent ink jet printer is immediately wound around a take-up roll 21 in the printer. In this step, the undried ink is transferred to the other surface 10 of the support 2 and soils the support. The three major drawbacks have been clarified. These are all disadvantages resulting from the poor drying properties of water-based and solvent inks.
In addition, in the back-sticking adhesive display, as described above, a large number of bubbles are mixed between the window glass and the adhesive surface, appearing as a large number of convex bulges on the surface, and applying a fluorescent lamp from the back side There is a problem that the bubbles are not exposed to light and cannot be used as an electric display.
An object of the present invention is to provide a backing display object that solves all of these four drawbacks.

In Patent Document 1, a toner image by an electrophotographic copying machine is once formed on a transfer paper, the toner image is further thermally transferred onto the surface of the micro sucker 4, and the window glass or transparent acrylic is used by using the suction force of the micro sucker. A method of backing a display object on a plate is disclosed. However, with this method, when the glass is covered with a window glass or a transparent acrylic plate and exposed to sunlight for 3 months, the toner adheres to the glass and the transparent acrylic plate and transfers to the glass surface, making it difficult to remove the toner. It has become clear that it will be a difficult task.

In addition, Patent Document 2 reports a method for producing a backing display by thermocompression bonding of a sheet printed with sublimation ink to a micro suction cup. However, an image printed on the surface of the micro suction cup has a sublimation ink. There is a defect that the outline of the image is blurred and does not become a product due to sublimation.
An object of the present invention is to provide a backing display that can solve these problems all at once.

Means to be Solved by the Invention

The present invention relates to a backing micro sucker display 5 that outputs and prints UV curable ink on a micro sucker surface with an ultraviolet curable ink jet printer as a method for solving the above-mentioned drawbacks in the backing micro sucker display. .
As shown in FIG. 8, the ultraviolet curable ink landed from the ultraviolet curable ink jet printer lands on an innumerable fine recessed hole 19 having a diameter of 5 to 300 microns formed on the surface of the micro suction cup, and is instantly cured by ultraviolet rays. At the same time, the ultraviolet curable ink that has landed on the periphery of the recessed depression 19 is also instantaneously cured. The UV curable ink is made of almost 100% UV curable resin that does not contain a solvent, and there is almost no solvent diffusing, and it is completely cured instantaneously.

Unlike water-based inks and solvent inks, the UV curable ink 7 landed in the concave depression 19 and lost its adsorption power. Of course, the ultraviolet curable ink landed around the concave depression hole also lost the adsorption power of the micro sucker. Let In order to prevent the backside display from falling off despite the disappearance of the suction force of the micro sucker, it is necessary to leave a residual portion 14 on which the micro sucker is not printed in output printing. This is because the suction force of the remaining portion 14 not printed by the micro suction cup does not disappear. For example, in the case of full-color solid output printing, the remaining portion 14 not printed by the micro sucker does not remain, so the adsorption power is completely lost, and the display object falls off when it is backed. On the other hand, a printed matter without solid printing naturally has a residual portion 14 which is not printed on the output of the micro sucker. Therefore, even if it is attached to a glass plate or a transparent resin plate, the display matter is supported by the adsorption force of the residual portion 14. It will not drop out.
In addition, a large number of air bubbles mixed between the unprinted residual part and the glass are absorbed and disappeared by the concave depression holes of the micro suction cups, and do not appear as convex bulges on the surface. When a fluorescent lamp is applied from the back, the bubbles are not lifted by light, and the display object is free from defects.
Output printing of UV curable ink landed from UV curable ink jet printers has been described. However, in screen printing and offset printing, some devices have a drying oven that prints a micro sucker with UV curable ink and cures with an UV lamp. The present invention is also applicable to screen printing and offset printing.

I found out that I was dropped from. Table 1 shows the presence / absence relationship between the ratio of the remaining area of the unprinted portion and the dropout of the micro sucker display when the backing micro sucker display (A4 size) has its own weight of 20 g and its own weight of 50 g.
The micro sucker display is composed of PVC film 100μ (thickness) and PVC film 500μ (thickness) / micro sucker (thickness 80μ) / release paper. The release paper is peeled off and the micro sucker is made with UV curable ink. Output printing was performed at a buildup thickness of 12 microns. The expansion ratio was 2.0.

○ Do not fall off by backing on a smooth glass plate. × Remove and paste onto a smooth glass plate. Adsorption force is based on JISZ0237.

In the test of Table 1, the unprinted residual part 8 does not have to be in a specific part of the micro suction cup. For example, in the case of A4 size, even if the printed part 15 is solid as shown in FIG. If the remaining portion 8 that is not output printed is 5%, there is no dropout. Further, as shown in FIG. 6, even if there are residual portions 8 that are not printed, even if they are scattered, the total area is 5% or more. However, it is easily guessed that the area ratio of the remaining portion 8 is required to be 5% or more so that the weight of 50g or more does not fall off, but if it exceeds 90%, the output printed portion 15 becomes too small and the display object is displayed. No longer fulfills its role.

◎は完全にインク移転なし、○は僅かの移転痕跡が見られる ×インク移転あり
平滑度は王研式測定による。吸着力はＪＩＳ０２３７による。吸着力の単位はＮ／２５ｍｍ
以上の結果よりインクジェットプリンターで出力された裏張りミクロ吸盤表示物５は水性インクであれ、溶剤インキであれ支持体の表面平滑度が粗な上質紙、不織布は未乾燥インクのインク転移汚染が少ない。表面平滑度が高い支持体、例えばキャストコート紙、ポリラミ紙は未乾燥インキの転移汚染が発生する。一方、シリコーン樹脂を塗布して剥離処理された支持体剥離処理ポリエステルフイルムの場合、水性インクであれ、溶剤インクであれ表面平滑度が高いにもかかわらず未乾燥インクが支持体２の他の面１０への転移汚染することはない。紫外線硬化インクは各種支持体に対して未乾燥インクの転移汚染は発生してない。本考案は以下に示す如く支持体の他の面が剥離処理された裏貼りミクロ吸盤表示物に関する。
ミクロ吸盤に紫外線硬化型インクジェットプリンターで出力印刷後、出力印刷された出力印刷物は図２如く巻き取りロール２１に巻き取られるのであるが、この時巻き皺の発生もなくきれいに巻き取りロール２１に巻かれるには、支持体の他の面と出力印刷されたミクロ吸盤４との間に一定の滑りが必要になってくる。表面平滑度が粗な支持体である上質紙、不織布の場合は良く滑り合うので絞まったロールが出来上がるのであるが、表面平滑度が高い支持体、例えばキャストコート紙、ポリラミ紙はポリエステルフイルムの場合は滑り合わないため巻き皺１３が発生した巻取りロール２１になる（図９）。表面平滑度が高いポリエステルフイルムにおいて巻き皺を無くす方法は、ポリエステルフイルムの表面に滑りやすい剥離処理剤１１を施すことである。本考案はトーレシリコーン（株）の剥離剤ＳＲＸ２１１を剥離処理剤として使うことにより巻き皺の無い、絞まった巻き取りロール２１を得ることが出来た。剥離処理剤はシリコーン樹脂、フッ素樹脂が良い。
出力印刷されない残留部分が７０％以上になると吸着力７０％以上残存していることになり、支持体２の他の面１０とミクロ吸盤１との吸着力は高く滑りにくい。従って出力印刷されない残留部分８の割合が高まるほど巻き取りロール２１内でのミクロ吸盤１と支持体２の他の面１０との滑りが悪くなり巻き皺が発生し易くなる。この意味でポリエステルフイルムの表面に滑りやすい剥離処理を施すのが良い。ミクロ吸盤のポリエステルフイルム面に対する吸着力は０．４５Ｎ／２５ｍｍに対して剥離処理したポリエステルフイルム面に対する吸着力は０．０４Ｎ／２５ｍｍと１／１０と小さくなる。このことは巻き取りロール２１を展開してミクロ吸盤表示物を引っ張り出すに、ポリエステルフイルム支持体の他の面が剥離処理されていると抵抗がなく引っ張り出し易くなる。Table 4 shows the results of confirming the presence or absence of occurrence of ink transfer contamination on the various supports 2 in the micro sucker display with 70% remaining portion 14 not printed on the micro sucker by various ink jet printers. The color laser printer is the result of checking the presence or absence of toner transfer contamination on the support by stacking 10 A4 size output prints immediately after output printing.

◎: No ink transfer, ○: Slight trace of transfer is observed × Ink transfer: Smoothness measured by Oken's method. Adsorption power is based on JIS0237. Unit of adsorption power is N / 25mm
Based on the above results, the backing micro sucker display 5 output by the ink jet printer is water-based ink or solvent ink, and the high-quality paper having a rough surface smoothness of the support, the nonwoven fabric has less ink transfer contamination of undried ink. . Supports with high surface smoothness, such as cast coated paper and polylaminated paper, cause transfer contamination of undried ink. On the other hand, in the case of a support release-treated polyester film that has been subjected to a release treatment by applying a silicone resin, the undried ink remains on the other side of the support 2 regardless of whether the aqueous ink or solvent ink has high surface smoothness. No transfer contamination to 10. The ultraviolet curable ink does not cause transfer contamination of the undried ink to various supports. The present invention relates to a backed micro-suction cup display in which the other surface of the support is peeled off as shown below.
After the output printing is performed on the micro sucker by the ultraviolet curable ink jet printer, the output printed product is wound around the winding roll 21 as shown in FIG. In order to be removed, a certain amount of slip is required between the other surface of the support and the micro-suction cup 4 that has been output printed. In the case of fine paper and nonwoven fabric with a rough surface smoothness, it will slide well because it slides well, but the support with high surface smoothness, for example, cast coated paper, polylaminated paper is a polyester film Since they do not slide together, the winding roll 21 in which the curl 13 is generated (FIG. 9). A method for eliminating curling in a polyester film having a high surface smoothness is to apply a slippery release agent 11 on the surface of the polyester film. In the present invention, by using the release agent SRX211 of Torre Silicone Co., Ltd. as a release treatment agent, it is possible to obtain a squeezed take-up roll 21 free from curl. The release treatment agent is preferably a silicone resin or a fluororesin.
When the remaining portion that is not printed out is 70% or more, the adsorption force of 70% or more remains, and the adsorption force between the other surface 10 of the support 2 and the micro suction cup 1 is high and is difficult to slip. Accordingly, the higher the ratio of the remaining portion 8 that is not output printed, the worse the slippage between the micro suction cup 1 and the other surface 10 of the support 2 in the take-up roll 21, and the more likely the wrinkle is generated. In this sense, it is preferable to perform a slippery peeling treatment on the surface of the polyester film. The adsorption force of the micro suction cup to the polyester film surface is 0.45 N / 25 mm, and the adsorption force to the peeled polyester film surface is 0.04 N / 25 mm, which is 1/10. This means that when the take-up roll 21 is expanded to pull out the micro sucker display, if the other surface of the polyester film support is peeled off, there is no resistance and it is easy to pull out.

The invention's effect

The backed micro sucker display 6 output and printed by an ink jet printer using water-based ink or solvent ink is inevitably light in color, and undried ink is transferred and contaminated on the other surface of the support in the take-up roll in the printer. To do. In addition, the micro-suction display displayed on the window glass and the transparent acrylic plate will cause ink transfer contamination on the window glass and the transparent acrylic plate in 3 months. In the case of the back-sticking adhesive display, many bubbles are mixed during the sticking work. On the other hand, according to the back-coated micro sucker display printed with the UV curable ink jet printer using the UV curable ink of the present invention, ink transfer contamination does not occur even inside the printer, and it was embraced during construction The bubbles are absorbed by the recessed depressions 19 and disappear. Furthermore, no ink transfer contamination is observed on the adherend even after two years have been applied to the glass surface and the transparent resin plate surface.

In the present invention, the micro sucker 1 formed on one surface 10 of the support 4 is output printed with an ultraviolet curable ink using an ultraviolet curable ink jet printer, and at least a residual portion 8 that is not output printed remains, and is repeatedly applied and peeled off. This is a back-fitted micro sucker display 5 to be displayed.

FIG. 4 is a cross-sectional view of the backing micro sucker display 5 that has been peeled off the release paper 3 from the micro sucker label 6 (FIG. 3) and output printed with the ultraviolet curable ink 7.
First, the production method of the micro sucker label 6 is acrylic copolymer DICNAL MEP20 100 kg, foam stabilizer DICNAL M40 10 kg thickener DICNAL MX 10 kg crosslinker GX 20 kg (both Dainippon Ink and Chemicals) plasticizer FBXP (Dahachi Chemical) 7 ka A foamed acrylic emulsion liquid having a foaming ratio of 2.0 times was prepared by mixing air into the acrylic copolymer emulsion mixed with the above through a mechanical foaming machine “Oaks mixer”. Using a 1300 mm wide comma coater, 160 g / m ² was applied to the back side of a transparent 75 μ polyester width 1270 mm (Toyobo product A4300) having a smoothness of 10,000 and a gloss of 95% to form a micro sucker 4 by drying at 140 ° C. for 3 minutes. Then, 30 μm stretchable polyethylene film (TDM-1 Tama Poly Co., Ltd.) was laminated on the micro sucker 4 as a release film 3 to produce 600 m of the micro sucker label 6 and stored for 3 weeks. The micro sucker was formed with about 100,000 concave depressions 19 having a diameter of 5 to 300 μm / m ² .

The polyethylene film which is the peeling film 3 of the micro sucker label 6 is peeled off by hand, and the ultraviolet curable ink 7 is applied to the surface of the micro sucker 4 which is exposed with an ultraviolet curable ink jet printer (available from NUTEMPo Nour Japan Co., Ltd.). Simultaneously with the output printing, the back-coated micro sucker display 5 in which the ink was cured by the ultraviolet irradiation lamp 16 was output and printed by 13 m and wound up on a take-up roll 21 in the printer. The output printing was a single color printing of a floral pattern. This was a design pattern in which the remaining portion 8 that was not output printed was about 50%. The output-printed back-coated micro sucker display 5 was unwound after 13 minutes by unwinding the take-up roll 21 and taken out 13 m to confirm the presence or absence of ink transfer contamination on the support. No transfer contamination was seen. The UV curable ink 7 landed on the micro suction cup hardens and closes the concave depression hole 19 and has a thickness of about 12 μm, and the adsorption force of the output printed portion 15 has completely disappeared, but the output is not printed. The adsorption power of part 8 was completely alive.
One day after output printing, if the air that has been embraced by pressing the backed micro-suction display 1m with the squeegee so as to contact the window glass 17 is degassed, the unprinted residual portion 8 is adsorbed on the glass surface and the micro-suction display is displayed. 5 was neatly backed without falling off. It was stuck or peeled off repeatedly for alignment, but it was adsorbed well each time. When the fluorescent lamp was illuminated from the inside of the window at night, it became a beautiful display for electric decoration due to the diffused reflection effect of the micro sucker.
The window glass 17 hits well on the western side, and after 3 months, the micro-sucking display 5 for backing was peeled off by hand, but it was easily peeled off. There was no transfer contamination of the ultraviolet curable ink to the window glass 17.

1 g / m ² of a release treatment silicone resin (Toray Silicone SRX211) was applied to the other side of the support = transparent 75 μpolyester (Toyobo product A4300), dried at 140 ° C., and then foamed on one side of the transparent 75 μpolyester After applying a foam acrylic emulsion liquid with a magnification of 3.0 times to 160 g / m ^{2 and} uniformly drying at 140 ° C. for 3 minutes to form a micro sucker 4, 30 μm stretchable polyethylene film (TDM-1 Tamapoly Co., Ltd.) 300 m of the micro sucker label 6 was produced by laminating it on the micro sucker as a release film, and stored for one week. The micro suction cup was formed with about 50,000 fine recessed holes 19 having a diameter of 5 to 300 μm / m ² .
While peeling off the release film 3, 5 m could be wound up tightly on the take-up roll 21 with no generation of wrinkles while performing output printing on a micro sucker with an ultraviolet curable ink jet printer (MIMAKI Engineer UJV = 160). . The output printing was a two-color print with a heart pattern (FIG. 7). This was a design pattern in which the remaining portion that was not output printed was about 70%. The micro sucker display 5m wound up on the take-up roll 21 was coated with the release treatment agent silicone resin on the support, so that the support was slipped tightly with the micro sucker. Further, when the take-up roll was unfolded and the micro-suction cup display was taken out, the suction resistance of the micro-suction cup was small, and it could be easily taken out without causing ink transfer contamination to the other surface 10. One day after output printing, if the air bubble that is held by pressing the backed micro sucker display 1m with the squeegee so that it touches the window glass 17 is degassed, the remaining unprinted portion 8 is adsorbed to the window glass and the micro sucker display 5 was backed without falling off. It was stuck or peeled off repeatedly for alignment, but it was adsorbed well each time. When the fluorescent lamp was illuminated from the inside of the window at night, it became an electric display with no bubbles due to the diffused reflection effect of the micro sucker.

1 g / m ² of a release treatment silicone resin (Toray Silicone SRX211) was applied to the other side of the support = transparent 75 μpolyester (Toyobo product A4300), dried at 140 ° C., and then foamed on one side of the transparent 75 μpolyester 3 times magnification foamed acrylic emulsion liquid was applied 160g / m ² and dried uniformly at 140 ° C for 3 minutes to form micro sucker 4, and then 30μ stretchable polyethylene film (TDM-1 Tamapoly Co., Ltd.) was peeled off The film was laminated on a micro suction cup as a film to produce a micro suction label 6 of 1270 mm × 300 m and stored for one week. The micro suction cup was formed with about 50,000 fine recessed holes 19 having a diameter of 5 to 300 μm / m ² . 1270mm x 300m cut to A2 size (594x420mm), after removing the stretchable polyethylene film, the flower designed to be 30% of the unprinted residual part 8 on the exposed micro sucker surface The pattern was screen-printed with ultraviolet curable ink (product of Teikoku Ink Co., Ltd.) with a 100 mesh screen to complete 30 A2 size micro sucker displays 5. The ink was completely cured when irradiated with a UV irradiation lamp in a subsequent process for 10 seconds. One day after printing, when the backed micro sucker display is pressed against the window glass 17 with a squeegee and the air is embraced, the unprinted residual portion 8 is adsorbed on the glass surface and the micro sucker display is displayed. 5 was neatly backed without falling off. It was stuck or peeled off repeatedly for alignment, but it was adsorbed well each time. Illuminating a fluorescent lamp from the inside of the window at night resulted in a beautiful display for lighting.
