Here, FIG. 1 is a perspective view of a stain prevention sheet according to the first embodiment of the present invention, FIG. 2 is an exploded side view thereof, FIG. 3 is a partial sectional view thereof, and FIG. 2
FIG. 7B is a cross-sectional view of the stain prevention sheet according to the embodiment, and FIG. 7B is a plan view of the stain prevention sheet according to the modification.

As shown in FIGS. 1 to 3, a dirt preventing sheet 10 according to a first embodiment of the present invention includes first to third release sheets 11 to 13 in a laminated state, First to third adhesive layers 14 to 16 provided on the intermediate portion of the first to third release sheets 11 to 13 and on the back surface side of the third release sheet 13 as the lowermost layer; And a belt-like sheet 17, 18 which is an example of an adhesion-suppressing layer attached to the back side of the second adhesive layer 14, 15. Less than,
These will be described in detail.

The release sheets 11 to 13 are made of PE
T (polyethylene terephthalate), polyester,
A thin resin sheet of polyethylene, polyvinyl chloride, polyvinylidene chloride or the like is used. It is more preferable that the resin sheet has high transparency, but it is also possible to slightly change the transparent color and the opaque color for each layer.
It is easy to determine the layer of the resin sheet. Also,
In order to distinguish each of the release sheets 11 to 13, it is also possible to write letters and symbols or the like.

[0008] The first to third adhesive layers 14 to 16 are
It is preferable to use an acrylic ester or a natural rubber-based adhesive. In this case, when the first release sheet 11 is peeled off, the second and third release sheets 12 and 13 are peeled off at the same time. , The third adhesive layer 1
6> The second adhesive layer 15> The adhesive strength is preferably weakened in the order of the first adhesive layer 14, whereby the first adhesive layer
From the release sheet 11 in this order. The adhesive strength of the adhesive layers 14 and 15 may be reduced by appropriately adding impurities to the same adhesive, or the type of the adhesive may be changed.

Then, the second and third release sheets 12, 1
3, the first and second release sheets 1 on the surface
Release coating layers 19 and 20 are formed in order to prevent an adhesive from remaining when 1 and 12 are peeled off. As the release coat layers 19 and 20, a polyamide-based or nitrocellulose-polyamide-mixed system is used, so that even if the release sheet on the upper surface is peeled off, the surface becomes smooth.

The band-like sheets 17 and 18 have a width of 1-2.
It is made of a thin sheet of about 0 mm, and suppresses the adhesive force of the adhesive in the attached portion. As a material, it may be a paper material, a thin synthetic resin layer such as polyester, polyethylene, polyvinyl chloride, polyvinylidene chloride,
It may be a printing ink layer or a coating film layer. It is preferable to provide a plurality of belt-like sheets 17 and 18 at a mounting pitch of 5 to 20 cm. In addition, upper and lower belt-like sheets 1
The mounting positions of 7, 18 may be overlapped, but if they are overlapped, the part is easily peeled off. Therefore, it is preferable to change the mounting position within a range of about 0.5 to 8 cm.

It is also possible to arrange the upper and lower belt-like sheets 17, 18 in an intersecting state. In this case, the position where the first release sheet 11 is peeled can be clearly distinguished. Further, a synthetic resin sheet having low adhesiveness is used for the belt-shaped sheets 17 and 18 themselves, and the back sides (see FIG. 2) of the belt-shaped sheets 17 and 18 are joined to the lower release coating layers 19 and 20. It is also possible to do so. In this case, it is also possible to use a normal synthetic resin sheet or paper for the belt-shaped sheets 17 and 18 and apply an adhesive having a weak adhesive force to the back surface, and furthermore, to apply the back surface (and the front surface) of the synthetic resin sheet to the front surface. Treatment can also be used to improve adhesion. The belt-like sheets 17 and 18 can use a transparent synthetic resin layer. For example, by forming a colored synthetic resin layer, a printing ink layer, and a coating film layer, the color and / or pattern can be changed. There is an advantage that it can be made different from each other and can be easily identified from the outside, thereby making it easy to confirm the peeling position.

On the back side of the third adhesive layer 16, a release paper 21 which is peeled off during use is adhered. The release paper 21 is made of a relatively thick paper, and has a release coat layer formed on the surface so that it does not firmly adhere to the third adhesive layer 16.

When using the stain prevention sheet 10 configured as described above, first, the stain prevention sheet 10 is cut in accordance with the wall surface to be stuck. Then, the release paper 21 on the back side is peeled off and adhered to the wall surface so that air or the like does not remain inside. In this state, the construction is completed. If the surface of the first release sheet 11 is soiled by use, a cut such as a razor is made at the end of the portion where the belt-shaped sheet 17 is located, and an adhesive tape is applied to the surface of the first release sheet 11 on one side. Then, the first release sheet 11 is peeled off, and then the first release sheet 11 on the other side is peeled off by the same procedure. Thereby, the second release sheet 1
2 is exposed. If the second release sheet 12 is soiled, the same procedure is used to remove the second release sheet 12 from the portion of the belt-shaped sheet 18.
Is peeled off.

Next, referring to FIG.
The stain prevention sheet 23 according to the embodiment will be described. In the stain prevention sheet 23, the stain prevention sheet 23 is applied to the back side of first to third release sheets 24 to 26 made of a transparent or translucent synthetic resin sheet. In the first to third adhesive layers 27 to 29, the adhesive force of the adhesive becomes weaker in order toward the surface. In addition, release coating layers 30 and 31 are provided on the surfaces of the second and third release sheets 25 and 26 so that the adhesive on the surface does not adhere. Therefore, when using the stain prevention sheet 23, after cutting to a predetermined area, the release paper 32 on the back side is peeled off and adhered to the wall surface. Then, when the surface becomes dirty, an adhesive tape or the like is stuck to the surface of the first release sheet 24, and only the first release sheet 24 is peeled off to expose the second release sheet 25. Next, when the surface of the second release sheet 25 becomes dirty, the second release sheet 25 is peeled off in the same procedure. As shown in FIG. 4 (B), the adhesive is not applied to all or some of the corners of the square antifouling sheet 23, or the peeling section 33 is provided with an extremely weak adhesive force even when applied. The first and second release sheets 24 and 25 can be further easily separated.

In the above embodiment, the release sheet is 3
Although the case of layers has been described, the present invention is applicable to two layers or four or more layers. Also, it is free to put a printed pattern or the like on the release sheet. Furthermore, the adhesion suppressing layer also includes a thread, a string, a piano wire, a tex, and a thin tape, and in this case, it is preferable that these ends protrude from the periphery of the release sheet. , The surface release sheet can be peeled off. More preferably, a thread, a string, a piano wire,
By changing the color of the adhesion suppressing layer composed of one or more of a tape and a thin tape and, if possible, changing the printing, the adhesion suppressing layer of each layer can be distinguished.
