Abstract

PURPOSE: To obtain such a sticker having excellent handling property that air bubbles are hardly included between the sticker and the surface where the sticker is to be adhered and that the sticker can be easily peeled from the surface by specifying the layer structure of the sticker. CONSTITUTION: A vinyl chloride sheet 1 has a printed ink layer 3 which indicates the content such as advertisement and a transparent resin film layer 2 as a protective film layer on the ink layer 3. An adhesive layer 4 is formed on the back surface of the vinyl chloride sheet 1 and a release sheet 5 is attached to the adhesive layer 4. When the sticker is to be adhered on a wall or the like, the release sheet 5 is removed to expose the adhesive layer 4. The vinyl chloride sheet 1 is preferably 80-150μm thickness (more preferably 100-120μm), and the total thickness of the vinyl chloride sheet 1 and the transparent resin film layer 2 is 180-300μm (preferably 200-250μm).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sticker, particularly a sticker suitable for advertisement.

[0002]

2. Description of the Related Art Conventionally, an advertisement sticker used in the inside of a train car or the premises of a train station has a printed thin resin sheet provided with an adhesive layer on the back surface, which can be used on a wall surface or a glass surface. Pasted on.

[0003]

Unlike conventional hanging advertisements, the above-mentioned conventional advertising stickers are not frequently replaced, and are usually posted for a long period of time. Therefore, conventionally, the handling property of the sticker itself, the easiness of sticking it to the wall surface, the easiness of peeling it, etc. have not been regarded as a serious problem. However, assuming, for example, an advertising sticker that needs to be replaced as frequently as a hanging advertisement, the conventionally used stickers have the following problems.

That is, since the conventional advertising sticker has a very thin sheet, when the peeling sheet on the back side is peeled off and stuck to a wall surface or the like, the sheets are curled and the sheet parts are stuck to each other. However, there is a difficulty in handling. In addition, since the sheet is thin and easily deformed, there is a problem that bubble-like air easily enters between the wall surface and the like when it is attached to the wall surface and the aesthetic appearance is impaired. There is also the drawback that it is difficult.

In view of the above-mentioned problems of the conventional sticker, the present invention is excellent in handleability, and it is difficult for air bubbles to be taken in between the sticker surface and the sticker surface. It is an object of the present invention to provide a sticker structure suitable for an advertising sticker that can be peeled off and is frequently replaced.

[0006]

In order to achieve the above object, the present invention has the following constitution. (1) A vinyl chloride sheet having a thickness of 80 to 150 μm having a printing ink layer on the front surface and an adhesive layer on the back surface, and a transparent resin film layer formed on the surface of the vinyl chloride sheet, A sticker characterized in that the total thickness of the vinyl chloride sheet and the transparent resin film layer is 180 to 300 μm. (2) The sticker according to the above (1), wherein a release sheet is attached to the adhesive layer on the back surface of the vinyl chloride sheet.

[0007]

The sticker of the present invention has a thickness of 80 to 150 μm.
m vinyl chloride sheet and a transparent resin film layer formed on the surface of the vinyl chloride sheet, and the total thickness of the vinyl chloride sheet and the transparent resin film layer is 180 to 300 μm, so that the sticker itself has sufficient rigidity. Therefore, the handling property is good, and it is difficult to take in air bubbles in the space to be adhered, and furthermore, it can be easily peeled off from the surface to be adhered.

The vinyl chloride sheet is used as the base sheet of the sticker because the vinyl chloride sheet has a higher rigidity than other synthetic resin sheets, and is easy to handle as a sticker and prevents air bubbles from being taken in. Because it is effective. If the thickness of the vinyl chloride sheet is less than 80 μm, sufficient rigidity cannot be imparted to the sticker. On the other hand, if the thickness exceeds 150 μm, the rigidity becomes excessive, resulting in poor deformability of the sheet and making the sticker curved. It is not preferable because it is easily peeled off from the end portion when it is attached to the wall surface of. Therefore, the thickness of vinyl chloride sheet is 80 ~
The thickness is 150 μm, preferably 100 to 120 μm.

If the total thickness of the vinyl chloride sheet and the transparent resin film layer is less than 180 μm, the sticker cannot have sufficient rigidity, while the thickness is 30
If the thickness exceeds 0 μm, the rigidity becomes excessive and the sticker is less likely to be deformed, which makes it difficult to attach the sticker to a curved wall surface and the like, and is also likely to spontaneously peel from the end portion, which is not preferable. Therefore, the total thickness of the vinyl chloride sheet and the transparent resin film layer is 180 to 300 μm, preferably 20.
It is set to 0 to 250 μm.

1 and 2 show one embodiment of the present invention, in which 1 is a vinyl chloride sheet and 2 is a transparent resin film layer formed on the surface thereof. The vinyl chloride sheet 1 has a printing ink layer 3 on the surface thereof, which represents the content of advertisements and the like.
And the transparent resin film layer 2 as a protective film layer is provided on the upper side thereof. An adhesive layer 4 is provided on the back surface of the vinyl chloride sheet 1, and a release sheet 5 is attached to this adhesive layer. When the sticker is attached to a wall surface or the like, the release sheet 5 is peeled off to expose the adhesive layer 4.

The thickness of the vinyl chloride sheet 1 is 80 to
150 μm (preferably 100 to 120 μm), and the total thickness of the vinyl chloride sheet 1 and the transparent resin film layer 2 is 180 to 300 μm (preferably 200 to 250 μm).
m). The method for forming the transparent resin film layer 2 is as follows.
Either a method of laminating a resin film on the surface of the vinyl chloride sheet 1 or a method of directly forming a film layer on the vinyl chloride sheet 1 may be used. The pressure-sensitive adhesive layer 4 and the release sheet 5 are not particularly limited and may be known ones used in conventional stickers.

[0012]

According to the above-described sticker of the present invention, the sticker is excellent in handleability, it is difficult to take in air bubbles between the sticker and the sticking surface, and the sticker can be easily peeled off from the sticking surface. Therefore, it is particularly suitable as an advertising sticker that is frequently replaced.
