DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dirt-preventive pressure-sensitive adhesive sheet, and more particularly to a dirt-preventive pressure-sensitive adhesive sheet to be adhered to a flat surface such as a wall surface, a window glass, etc., which requires dirt prevention.

[0002]

2. Description of the Related Art Conventionally, as the above-mentioned dirt-preventing pressure-sensitive adhesive sheet, a pressure-sensitive adhesive layer is provided on one side of the sheet, and a release paper or the like is coated on the surface of the pressure-sensitive adhesive layer and the other side of the sheet to protect the pressure-sensitive adhesive layer. A dirt-preventive pressure-sensitive adhesive sheet is used in which the pressure-sensitive adhesive layer is wound in the form of a roll with the surface of the pressure-sensitive adhesive layer as an inner winding surface or in a folded shape. However, in this dirt-preventive pressure-sensitive adhesive sheet, the bonding operation is performed while the peeling paper is gradually peeled off and the inner pressure-sensitive adhesive layer surface is pulled out after deciding the position to be bonded at the time of bonding. , And it was difficult to attach the sheet without impairing the appearance.

In addition, a roll-shaped dirt-preventive adhesive having a water-repellent coating layer of silicone or the like provided with an adhesive layer on the inner winding surface and a water-repellent coating layer of the inner winding surface on the outer winding surface so that the inner adhesive surface does not transfer to the outer winding surface. There is also a sheet, but also in this case, when sticking, the sticking work must be performed while gradually pulling out the inner pressure-sensitive adhesive layer, so workability is poor, and bubbles are easy to enter, and the same problem as above Have a point.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems in a dirt-preventive pressure-sensitive adhesive sheet to be pasted on a dirt-preventive surface. An object of the present invention is to provide a dirt-preventive pressure-sensitive adhesive sheet that allows a sheet to be adhered without causing air bubbles and without impairing the appearance.

[0005]

According to a first aspect of the present invention, there is provided a dirt-preventive pressure-sensitive adhesive sheet which is wound in a roll shape, and has an adhesive surface on an outer winding surface of the sheet. A material layer is provided, and a coating layer for preventing transfer of the adhesive material is provided on the inner winding surface.

Further, in the stain-preventive pressure-sensitive adhesive sheet according to the second aspect, a protective coating of an adhesive layer is provided on an outer peripheral surface of the roll-shaped sheet.
The dirt-preventing pressure-sensitive adhesive sheet according to claim 4, wherein a mark indicating the position of the rear-end of the roll is provided at the end of the rolled sheet. The surface is provided with a notch or perforation for cutting.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a dirt-preventive pressure-sensitive adhesive sheet according to the present invention. In addition,
These aspects are intended to illustrate one preferred embodiment of the present invention and do not limit the invention.

The antifouling pressure-sensitive adhesive sheet of the present invention is shown in FIGS.
As shown in FIG. 1, a sheet 1 is wound into a roll, and a known adhesive layer 2 is provided on an outer winding surface 4, and an inner winding surface 5 is provided.
Is provided with a coating layer 3 for preventing transfer of the pressure-sensitive adhesive layer 2 so that the pressure-sensitive adhesive layer 2 is not transferred when wound into a roll.

As a material of the sheet 1, a transparent plastic film such as a polyester film is preferably used, but a laminated material composed of an aluminum foil and various plastic films can also be used. A sheet on which a square or other pattern is printed can also be used.

A known adhesive is applied to the adhesive, and the adhesive layer 2 may be provided on the entire surface of the outer winding surface 4. May be. The coating layer 3 is preferably formed by applying water-repellent silicone or the like.

A sheet provided with an adhesive layer on one side and a coating layer on the other side may be formed by rolling a paper tube or the like as a core tube 9 so that the adhesive layer has an outer winding surface and the coating layer has an inner winding surface. In order to protect the adhesive layer 2 exposed on the outer peripheral surface, an adhesive layer such as a release paper or a release film is provided on the outer peripheral surface of the roll R as shown in FIG. Two protective coatings 6 are provided. As the protective coating 6, it is important that the texture of the sheet, the printed pattern of the sheet, and the like can be confirmed at the time of sale. Therefore, a transparent coating is preferable. Is also good.

For convenience in use, as shown in FIGS. 1 and 2, the rolled sheet 9 has
It is preferable to provide a mark 7 indicating the position of the end of the winding. Mark 7
Is displayed by attaching an appropriate mark seal or by printing. It is preferable that notches or perforations 8 are provided on the surface of the sheet at a predetermined pitch as shown in FIG. Instead of the notch or the perforation 8, the sheet may be provided with a printing pattern that also serves as a cutting mark, such as a grid pattern.

When using the above-mentioned dirt-preventive pressure-sensitive adhesive sheet of the present invention, after removing the protective coating 6 of the roll R, the sheet is peeled off from the mark 7 at the trailing end of the rolled sheet 1 to remove the wall surface or the like. On the sheet sticking surface, determine the sticking position and temporarily fix to that position. Next, the core tube 1 of the roll R
For example, a rotation holder for a commercially available carpet cleaning tape is inserted into the wall 0, and the sheet is attached to the wall while the roll R is pressed against the wall and rotated.

In the dirt-preventive pressure-sensitive adhesive sheet of the present invention,
Since the pressure-sensitive adhesive layer is formed on the outer winding surface, the pressure-sensitive adhesive layer surface is sent out to the wall surface each time the roll R rotates. Therefore, the sticking operation is easy, and the roll R is uniformly pressed on the wall surface, so that the entrapment of air bubbles can be avoided. A dedicated rotation jig may be prepared as a rotation holder for the roll R, but any jig can be used as long as the jig can be inserted into the core tube 10 and pressed and rotated. Is also good.

After sticking while sending out to a predetermined length,
The sheet is cut from the notch and perforation 8. When the cutting mark is displayed in a print pattern, cut with scissors or the like according to the mark. After use, the protective coating 6 is put on the roll R and stored. It is also possible to omit the mark 7 by winding the length of the rolled sheet by the length used once.

[0016]

Embodiments of the present invention will be described below. Example 1 Polyester film (polyethylene terephthalate)
An adhesive (acrylic rubber adhesive) is applied on one side (thickness: 50 μm) in a streak shape in the flow direction (longitudinal direction), and silicone is applied on the other side, and the adhesive layer and the adhesive layer are rolled, respectively. Forming a coating layer for preventing adhesion, using this as a core tube with a paper tube,
The adhesive layer was rolled up so that the outer layer had an outer winding surface, and the coating layer had an inner winding surface, and a protective coating was provided on the outer peripheral surface with a transparent release film to produce a stain-resistant adhesive sheet.

When the obtained antifouling pressure-sensitive adhesive sheet was adhered to a wall according to the above-mentioned procedure, the sheet could be extremely easily adhered to the wall without involving air bubbles. The sticking surface of the sheet had no irregularities, was extremely smooth, and had an excellent appearance.

[0018]

According to the present invention, there is provided an antifouling pressure-sensitive adhesive sheet which can be easily bonded, does not involve air bubbles, and can be bonded without impairing the appearance.
