[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tack sheet for makeup which is easy to apply.

[0002]

2. Description of the Related Art Tack sheets are often used for decoration of walls and ceilings because they can be constructed on site. The tack sheet is composed of a decorative sheet provided with a decorative layer on a base sheet such as a plastic sheet or paper, an adhesive layer applied to the back surface, and a release paper applied to the adhesive layer for easy storage and transportation. You.

[0003] When the tack sheet is installed, after positioning, the release paper may be peeled off and attached to an adherend such as a wall. You may get wrinkled on the tack sheet. In such a case, the tack sheet must be peeled off from the adherend and re-attached. This leads to a delay in the process, and it is generally difficult to peel off the tack sheet once adhered, often leading to breakage of the decorative sheet.

[0004] As a countermeasure, non-adhesive fine particles are thinly applied on the surface of the adhesive layer to reduce the adhesive strength, or an adhesive having a low adhesive strength is used. But,
If the adhesive strength is weak, there is a problem that the durability of the construction product is reduced.

[0005] In addition, construction methods have been devised so as not to shift the sticking position, but all of them are complicated and time-consuming, so that they are not practical.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tack sheet which can be constructed by a simple method and can be accurately adhered to a predetermined position without a skilled worker.

[0007]

As shown in FIGS. 1 and 2, the tack sheet according to the present invention is a tack sheet in which an adhesive is applied to the back of a decorative sheet (1) and a release paper (3) is applied thereto. Wherein the release paper (3) has a hole (31) for partially exposing the pressure-sensitive adhesive layer (2).

The release paper may be made of the same material as that conventionally used for the tack sheet, such as a synthetic resin sheet such as polyester or polyolefin, or a paper obtained by releasing a paper with a silicone resin. The shape of the holes provided in the release paper is arbitrary such as a circle, an ellipse, and a square. The arrangement and number of the holes are appropriately determined in consideration of the use of the tack sheet and the adhesive strength of the adhesive.

As shown in FIG. 1, the decorative sheet is a plastic sheet made of polyvinyl chloride or polyester such as polyethylene terephthalate, a metal foil of stainless steel, aluminum or the like, paper, or a laminate thereof. A PVC wallpaper formed by forming a polyvinyl chloride layer on a body, for example, a backing paper, is used as a base sheet (11), and printing of a pattern (12), vapor deposition of metal, embossing, kneading of a coloring agent, and the like are optionally performed. A decorative layer is provided in combination.

The pressure-sensitive adhesive is selected from known materials such as rubber-based and acrylic-based materials in consideration of the material of the adherend to which the decorative sheet and the tack sheet are to be attached.

[0011] The tack sheet of the present invention can be wound on a roll or cut into sheets to be stacked for storage and transportation in the same manner as the conventional tack sheet. In that case, further apply a non-perforated release paper on top of the perforated release paper so that the adhesive exposed from the holes of the release paper does not stick to the surface of the decorative sheet. Is preferred.

[0012]

The tack sheet according to the present invention is constructed according to the procedure shown in FIGS.

First, as shown in FIG. 3, while positioning the tack sheet, the tack sheet is temporarily bonded to the adherend (6) using the adhesive exposed from the holes of the release paper (3).

Next, as shown in FIG. 4, about half of the decorative sheet (1) and the release paper (3) are peeled off, and the release paper at the peeled portion is cut off.

Subsequently, as shown in FIG. 5, the decorative sheet (1) at the portion from which the release paper has been cut is permanently bonded to the adherend (6). At this time, the part where the release paper remains remains temporarily bonded to the adherend (6), so that the actual bonding can be performed without shifting the bonding position.

Finally, the release paper is peeled off from the remaining part of the decorative sheet, and the permanent bonding is performed. Also at this time, since the half of the decorative sheet is already fully bonded to the adherend, the remaining portion can be fully bonded without shifting the bonding position.

[0017]

[Effects of the Invention] The tack sheet of the present invention can be stuck to an accurate position even by a non-skilled worker by employing a construction method utilizing temporary adhesion of a part of the adhesive.
