Abstract

PROBLEM TO BE SOLVED: To easily and accurately do work for pasting a large size of adhesive sheet including a wall sheet. SOLUTION: To easily make adjustment of the position and direction of pasting an adhesive sheet 1, a positioning part 3a which is relatively inferior in adhesion and effective for repasting is formed at the center of the adhesive face 3 on the back of a surface material 2. In executing, the positioning part 3a is pasted to determine the attitude of the adhesive sheet 1, but separated and readjusted, if defective. Then, the adhesive sheet 1 is gradually pasted toward the peripheries.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive sheet such as wallpaper or sliding paper, and more particularly, to a pressure-sensitive adhesive sheet that can be easily and accurately attached, and a method of applying the same.

[0002]

2. Description of the Related Art There is a wallpaper in which release paper is adhered to the back surface of a surface material via an adhesive layer so that the application operation can be easily performed even in ordinary households. According to this configuration, the sticking operation can be easily performed only by peeling off the release paper and pressing it.

However, if the user is not accustomed to it, it is difficult to apply it neatly so that air does not enter the inside (so as to prevent unevenness in the application). Therefore, a wallpaper as disclosed in JP-A-60-88197 has been devised. This wallpaper is made by making a vertical cut in the release paper so that the adhesive layer can be exposed little by little.Pull off the release paper in the middle and paste it, and then paste it in the end in order I have to.

However, in this configuration, since the adhesive strength (initial tackiness) of the adhesive layer is strong, it is difficult to re-attach once it has been applied. In other words, it was surprisingly difficult to achieve the correct posture, and sufficient attention was required.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to form a positioning portion which can be easily re-attached to an adhesive layer so that the attaching operation can be performed easily and accurately. .

Means for that purpose is an adhesive sheet in which an adhesive surface is formed on the back surface of the surface material and a release paper is adhered to the adhesive surface, and a part of the adhesive surface has, for example, low initial tackiness. It is a pressure-sensitive adhesive sheet having a positioning portion that can be easily reattached.

The positioning portion may be formed, for example, with reduced adhesive strength.

Further, in order to facilitate the work, it is preferable that the release paper is divided into at least a portion corresponding to the positioning portion and another portion.

In order to obtain an adhesive sheet for use on walls and sliding doors,
The surface material is formed for wallpaper or fusuma paper.

[0010] Further, at least an adhesive sheet having a positioning portion which can be easily re-attached to the adhesive layer on the back surface of the surface material is attached to the positioning portion on the surface to be attached, and the posture is determined. Characterized in that it is a method of applying a pressure-sensitive adhesive sheet.

[0011]

According to the above construction, in the pasting operation, after the release paper is peeled off, the positioning portion formed on the adhesive layer is first adhered to determine the posture of the adhesive sheet. If defective, the positioning portion is peeled off and the posture is determined again. Then, the whole may be pasted so as to prevent sticking unevenness.

Since the positioning portion can be easily re-attached, correct positioning can be performed. For this reason, the desired and accurate attachment can be easily performed. Moreover, the positioning portion can be peeled off after pasting once, and does not damage the base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view of an adhesive sheet 1 used as wallpaper or fusuma paper. This adhesive sheet 1 forms an adhesive surface 3 by applying an adhesive to the back surface of a sheet-like surface material 2 formed for wallpaper or fusuma paper, and a release paper 4 is formed on the adhesive surface 3.
Are bonded together.

As shown in FIG. 1, a part of the release paper 4 is peeled off from a part of the adhesive surface 3 to form a positioning part 3a which can be easily re-attached. The fact that it is easy to reattach means that it can be peeled off relatively easily without remaining on the ground surface even after pasting once and without damaging the ground surface, and it is possible to paste again is there. For example, it is formed of an adhesive having a low adhesive strength. The formation position is, for example, an intermediate portion in the width direction, and is formed by applying a pressure-sensitive adhesive having a low adhesive strength to the appropriate width and band shape. The adhesive having a low adhesive strength may be, for example, an adhesive having a strength of about 150 to 250 g / inch when the other portion 3b has an adhesive strength of about 1500 to 2500 g / inch.

In order to stick the pressure-sensitive adhesive sheet 1 thus constructed to the surface 5 to be stuck (wall surface or sliding door), after the release paper 4 is peeled off, first, as shown in FIG.
On the surface 5 to be attached. At this time, the adhesive sheet 1
The position is determined, and if defective, the positioning portion 3a is peeled off and the position is determined again. Then, the whole may be pasted so that the pasting unevenness does not occur. Positioning unit 3
Since a can be easily re-attached, a can be correctly positioned.
For this reason, the desired and accurate attachment can be easily performed.

In order to facilitate the attaching operation, at least the positioning portion 3a as shown in FIG.
And the part corresponding to the other part 3b may be separated from the release paper 4. The release paper 4 may be divided by forming the cuts 6 only in the release paper 4 after the formation of the adhesive sheet 1. At this time, the release paper 4 may be displayed with the indication of the positioning portion 3a, the indication of the order of peeling, and the like. At the time of pasting, the release paper 4a corresponding to the positioning portion 3a is peeled off, and after performing correct positioning, the release paper 4b corresponding to the other portion 3b can be peeled off and pasted. There is no possibility that the part 3b other than the part 3a is accidentally stuck to the surface 5 to be stuck, and the positioning work is easily performed.

As shown by the imaginary line in FIG. 3, the release paper 4b other than the release paper 4a corresponding to the positioning portion 3a is
Put a plurality of cuts 7 so that it can be divided into narrow widths,
If the bonding operation is performed while being peeled off little by little from the intermediate portion side, the operation of bonding the portion 3b other than the positioning portion 3a can be performed carefully, and a beautiful bonding state without unevenness can be obtained.

FIG. 4 shows a positioning section 3a having a predetermined width so that the adhesive sheet 1 can be stuck little by little.
Are formed at predetermined intervals.

In order to form the positioning portion 3a which can be easily re-attached, a pressure-sensitive adhesive having a low adhesive strength is used as described above. However, it may be performed using a re-adhesive adhesive material that can be attached, or it can be performed depending on the application area and application method of the adhesive. In FIG. 5, the same adhesive as that of the portion 3b other than the positioning portion 3a is formed by applying a parallel line at a predetermined interval. In FIG. 6, the same adhesive as that of the portion 3b other than the positioning portion 3a is formed by applying a large number of dots.
