Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be easily applied to indoor walls, windows, signboards, outdoor windows, and cars of stores and the like, and can be easily peeled off if necessary. The present invention relates to a poster sheet for advertisement that also has good storage stability when reused. Note that, in the present invention, the advertisement poster sheet is used in a broad sense, and includes not only advertisements and advertisements but also all types of printed displays.

[0002]

2. Description of the Related Art Conventionally, paper or plastic film used for advertising posters, sales promotion POPs, etc. is used.
When affixing to a wall, window glass, or signboard, it is often attached with a thumbtack or four corners with tape.

On the other hand, it has been a long time since so-called glued advertising posters having an adhesive applied to the entire back surface so that they can be stuck anywhere can be used. However, the biggest drawback of this is that it is difficult to apply it beautifully due to the incorporation of air and the generation of wrinkles (wrinkles) when it is attached to a window glass, a wall or the like.

[0004] To facilitate this difficult task,
Generally, a method of spraying and spraying soapy water on a window glass, a wall, or the like of an adherend, spraying the poster with glue thereon, and extruding the soapy water with a squeegee and pasting it is common. However, this method is good when the advertising poster is resistant to water, such as a plastic film, but cannot be applied to a paper poster that is weak to water.

As another method for facilitating the pasting operation, a method has been adopted in which the adhesive force of a glued advertisement poster or the like is extremely weakened so that the poster can be peeled off even if the pasting fails. However, it is necessary to have a professional with experience in that way to paste beautifully so that there is no air mixing or wrinkling, and this is a task that cannot be done by an amateur who pastes for the first time.

[0006] On the other hand, if it is possible to peel off the poster once pasted, it is often desired to peel it off and use it again. However, if the adhesive is sticky, there is a lot of dirt attached. It is not possible at present.

[0007]

As described above, the biggest drawbacks of glued advertising posters and the like are the difficulty in pasting and the inability to reuse them.

[0008] The present invention is an invention relating to a revolutionary method for solving the difficulty of sticking work. In particular, a large-sized glued advertising poster of 1 to ³ m ² is easily accessible to amateurs, and
The present invention relates to an epoch-making invention that can be applied in a short time.

[0009] Yet another problem with glued advertising posters and the like is that once glued advertising posters have been peeled off, they cannot be reused, but the present invention is also a fundamental improvement.

In other words, in view of the above-mentioned drawbacks, the present invention is an epoch-making glued advertisement having both ease of sticking work and reusability of an advertising poster or the like once used and peeled off. The purpose is to provide a poster for use.

[0011]

[Means for Solving the Problems] In order to solve the above-mentioned conventional problems, the present invention uses a micro suction cup having an adsorbing function instead of an adhesive when attaching an advertisement poster or the like. By using it instead, it is possible to construct an advertising poster sheet with a micro suction cup that can be easily applied and applied by an amateur, has good storage properties after use, and can be reused.

In the advertising poster sheet with micro suction cups of the present invention, a rough ink-jet coating layer is formed on one side of the printing sheet, and a micro suction cup is formed on the other side, and peeling is applied to the micro suction cup. As the film, an elastic and smooth ultra-thin film is used.

That is, the present invention is configured as follows.
The first invention is a 10- to 100-micron thick, often 2.
Forming an inkjet coating layer 1 of 0-30 microns;
An infinite number of fine and soft concave depressions having a diameter of 5 to 100 microns are formed on the back surface of the printing sheet 2.
With a micro suction cup for ink jet printing, a flexible micro suction cup 3 having a thickness of 00 micron is formed, and a release film 4 having a thickness of 10 to 100 micron for protecting the micro suction cup 3 is attached to the back surface of the micro suction cup 3. Features an advertising poster sheet.

The second invention is characterized in that, in the first invention, a surface protection film 8 is adhered to the surface of the ink jet coating layer 1.

A third invention is characterized in that, in the first or second invention, the release film 4 is made of a stretchable, smooth and ultrathin film.

According to a fourth aspect of the present invention, in the first or second aspect, the ink jet coating layer 1 has a rough surface, and when the advertisement poster sheet is wound up for reuse, the ink jet coating layer 1 It is characterized in that the rough surface and the micro suction cup 3 are slidably slidable and wound up hard.

[0017]

In the present invention, the micro sucker 3 is a dispensing solution in which fine bubbles are generated while mechanically blowing air into an acrylic emulsion liquid, and is applied to the back surface of the printing sheet 2 by a comma coater coating machine. Is sufficiently dried to form a foamed resin coating layer having a thickness of 100 to 1000 microns. On its surface are formed concave depressions 5 having a countless number of suction cups having a diameter of 5 to 100 microns.

The printing sheet 2 of the present invention refers to paper, synthetic paper, vinyl chloride film, polyester film, etc., on which the ink jet coating layer 1 can be formed. Inkjet coating layer 1
Is a coating layer that is formulated to absorb fine water-based ink particles 7 instantaneously and suppress bleeding of the ink, that is, a coating layer in which a specific inorganic pigment is solidified with a resin, and the surface thereof is a pigment. Most of the particles are roughened. As an example of the printing sheet 2, an extremely smooth sheet may be used as seen in ink jet printer paper of a commercially available computer.

The micro suction cup 3 has a diameter of 5 to 100.
It is made of a mixture of innumerable microbubbles of micron size and a flexible resin, for example, acrylic resin, and has innumerable microscopic depressions 5 formed in the surface thereof as shown in FIG. The countless fine concave depressions 5 exhibit a so-called pressure-sensitive suction force, and any surface may be used as long as the surface to be attached is smooth, and has a feature of pressure-sensitive suction. In addition, the advertising poster 6 having the micro suction cup 3 as an adsorption element can be easily peeled off by hand and does not have stickiness like an adhesive, so that it matches human physiology.

Although the micro suction cup 3 has begun to be used as an application of an adhesive tape, the present invention is characterized in that the ink jet coating layer 1 and the micro suction cup 3 are formed on both sides of the printing sheet 2, respectively. As a result, until now, only the professionals on the road could stick and construct,
This makes it possible to reuse an advertising poster after peeling, which has been difficult with a large advertising poster extending several meters wide. That is, the roll-up and unwinding of an advertising sheet can be performed by the inkjet coating layer 1 of the present invention. Was made smoother by making the surface substantially rough and the micro suction cup 3 slidably in contact with the rough surface during winding.

This will be described in detail.
And the like may be stored in a roll shape as shown in FIGS. 4 (A), (B) and (C). However, in the case of conventional glued advertising posters, for example, those pasted on glass or the like are manually peeled off for reuse, and rolled without a release paper, the exposed adhesive and inkjet coating layer Not only does it not roll neatly because it comes into contact and adhesion, but even if it could be wound, the adhesive part between the adhesive and the inkjet coating layer is forcibly peeled off when unwound, so the surface of the inkjet coating layer The prints were damaged due to the damage, and as a result, the advertisement poster could not be reused.

On the other hand, when the micro suction cup 3 of the present invention is formed on the back surface of the advertising poster instead of the adhesive, first of all, there is no stickiness, so that the surroundings are not inadvertently adhered. Very easy to handle. Also,
Since there is no stickiness, the wound storage is easy, and the winding is easily unwound and reused.

When the advertisement poster 6 is wound, the micro suction cup 3 comes into direct contact with the ink jet coating layer 1, but the micro suction cup 3 is adsorbed on the ink suction coating layer 1 because the surface of the ink jet coating layer 1 is extremely rough. They can be rolled without any slipping and tightening slightly, so they are extremely hard and compact. When the ink-jet coating layer 1 is extremely smooth, the suction force with the micro suction cup 3 increases and the winding becomes difficult. However, as compared with the case of the pressure-sensitive adhesive, the handling is easier and the storage after use is easier. There is a difference of cloud mud.

On the other hand, the advertising poster 6 with the micro suction cups
Is wrapped around, for example, a 3-inch core and stored in a package.
Since the thickness is relatively thick, 300 to 400 microns, 3
When wound around an inch core and stored, there is a risk that a wrinkle or a fold may occur due to a difference in the outer diameter of the wound advertising poster sheet. In order to prevent this, in the present invention, an elastic and smooth ultra-thin peeling film 4, specifically, a 15 to 50 micron thick polyethylene film, vinyl chloride film, polymethylpentene film or the like is used. are doing.

In particular, for winding the product using a non-stretchable polyester film for the printing sheet 2,
It is essential to use a peeling film 4 which expands and contracts following expansion and contraction of the micro suction cup 3. In addition, when the peeling film 4 which does not expand and contract following the product is used, wrinkles always occur. Therefore, in the present invention, a stretchable polyethylene film, polypropylene film, vinyl chloride film, or polymethylpentene film having a thickness of 15 to 50 microns is used.

In FIG. 1, an advertising poster 6 has an ink-jet coating layer 1 having a thickness of 10 to 30 μm which can be ink-jet printed on the surface of a printing sheet 2. Particles 7 are impregnated. In addition, on the back surface of the printing sheet 2, a number of fine and flexible concave depressions 5 having a diameter of 5 to 100 microns are formed in an infinite number of 100 to 1000.
A flexible micro suction cup 3 having a thickness of micron is formed, and a back surface of the micro suction cup 3 for protecting the micro suction cup 3 is provided on the back surface of the micro suction cup 3.
It is configured by sticking a release film 4 having a thickness of 0 to 100 microns.

FIG. 3 shows an advertisement poster 6 according to the second embodiment.
Is shown. The difference between the advertising poster 6 of the second embodiment and the first embodiment is that a surface protection film 8 is adhered to the surface of the ink-jet coating layer 1 via a pressure-sensitive adhesive layer 9. Same as in the first mode.

FIG. 4 is an exploded perspective view of the advertisement poster 6 in which a predetermined display print 11 has been applied to the ink jet coating layer 1, and FIGS. 4 (B) and 4 (C) show the advertisement poster. 6 shows a state in which 6 is hard and compactly wound around a paper tube 10.

The advertisement poster 6 has been manufactured through the following steps, and will be described below. First, a polyester film (polyester printing sheet) 1280 mm (Mitsubishi Paper Mills) with an inkjet layer for printing already coated on the surface
Apply a 1 mm thick foamed acrylic emulsion liquid (manufactured by Dainippon Ink) onto the backside of the plate by blowing a myriad of bubbles mechanically, dry it in a drying oven at 150 ° C for 3 minutes, and cool it naturally. Thereafter, a polypropylene film having a thickness of 20 μm was coated on the micro suction cup formed to a thickness of 250 μm with a laminator to produce an advertising poster sheet 600 m with a micro suction cup.

The product is wrapped around a paper tube 10 by winding it in a length of 30 m, and after confirming that no wrinkles or the like have occurred, the product is unwound, and the product is applied to an ink jet printing machine CJ-70 (manufactured by Roland Corporation) to obtain a designated design. 1200mm × 2000mm
Were printed on the inkjet coating layer to complete two advertising posters with micro suction cups.

One of the sheets is to be stuck on the outdoor glass of a store, so that an outdoor waterproof film, a 50 micron transparent matte vinyl chloride film M-009PN80 (manufactured by Lintec) is applied on the ink jet coating layer 1 of the advertising poster sheet with a micro suction cup. Over-laminated, wound around a 3-inch core and delivered to the construction store. The other piece was wound around a 3-inch core without overlamination and delivered to the construction shop.

In the adhering work of the outdoor glass of the advertisement poster 6, one amateur store employee was in charge of the adhering work. The advertising poster 6 with the micro suction cup was attached to the window glass by suction without sticking to the worker's hand. Peeling was performed several times to correct the sticking position, but the sticking operation was completed in 15 minutes. When the same adhering work was performed on an advertising poster with an adhesive, it was about 60
It took a minute.

One week later, the attached advertising poster was easily peeled off again by store employees and easily wound up and stored in a 3-inch paper tube for reuse. Three months later, the package was unpacked and unwrapped, and was again attached to the same window glass by a store employee again, completing the task in 12 minutes.

Another advertising poster 6 with a micro suction cup, which was wound around a 3-inch core and delivered to the construction store without overlamination, was also pasted, constructed and reused by one store employee in parallel. The same results of easy workability, easy peelability, easy storage and the like were obtained. In particular, 3
After unpacking after a month, the unwinding of the winding is achieved by the suction force between the inkjet coating layer 1 having fine irregularities on the surface and the micro suction cup 3, despite the fact that the winding is hard and compact on a 3-inch paper tube. Was easily unwound without damaging the weak inkjet coating.

[0036]

As described above, according to the present invention,
In the past, instead of pasting of advertising poster sheets with adhesive glue, which could only be done by professionals of signboards and interior shops, pasting using advertising poster sheets with micro suction cups, even amateurs, It became clear from the construction test that the work can be finished beautifully and easily in a shorter time than experienced professionals. Furthermore, the advertising poster sheet with a micro suction cup of the present invention can be said to be an environment-friendly product because it can be easily peeled off, can be reused and stored, and can be used many times.
