Abstract

PROBLEM TO BE SOLVED: To improve function by stacking a design sheet formed by adhering a printed PET film to a designated surface of a metallized PET film to be removable in a designated state. SOLUTION: A printed PET film 2 formed by making a print 22 on one side of a polyethylene terephthalate(PET) film 21 and a metallized PET film 3 formed by evaporating an aluminum metal layer 32 on one side of a PET film 31 are adhered to each other with the printed surface and the metal surface opposite to each other to form a design sheet 1. Then, plural sheets 1 are stacked, with the films 2 up by a weak adhesive, and lined with released paper to provide a wall surface face sheet thereon. The released paper is removed from the wall surface face sheet to stick the sheet to the wall surface, and when the upper sheet 1 is soiled, the sheet is separated to expose the lower sheet 1 repeatedly. Thus, each design sheet has the metallic surface on the lower side, so that the print on the lower side can be made invisible. Futher, at the time of separation, the evaporated part and the printed part can be prevented from remaining on the other design sheet.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved wall decorative sheet which is used by being adhered to various walls and flat surfaces such as an inner wall of a room, a tile surface of a kitchen, a door of a refrigerator, and an inner wall of an elevator.

[0002]

2. Description of the Related Art Conventionally, in order to prevent dirt on a wall or the like or to easily remove adhered dirt, a laminate of a plurality of transparent films or sheets is pasted on a wall. A wall sheet of a type in which the surface of a film or a sheet is sequentially peeled off when the surface of the film or the sheet becomes dirty to reveal a new surface is on the market.

[0003]

However, since the wall sheet of this type is entirely transparent, if the wall surface of the base is dirty, the dirt appears on the surface as it is. Moreover, even if the film or sheet is peeled off to reveal a new surface, the wall pattern of the base does not change, and the pattern and color do not change as when the wallpaper is replaced, and the fresh feeling I can't get it.

As a solution to such a problem, there has been proposed a wall sheet in which two films which have been subjected to printing or vapor deposition are joined (registered utility model No. 3033224).
issue). That is, this wall sheet has a plurality of layers of transparent sheets adhered on a release paper by an adhesive, and a transparent sheet in which a polyethylene terephthalate film (hereinafter, referred to as a PET film) and an olefin film are joined to each other. In this case, the metal layer is applied to the entire surface or a part of the lower surface of one of the PET film and the olefin film constituting each transparent sheet on the release paper side. In addition, instead of metal vapor deposition, a wall sheet in which a transparent sheet coated with a colorant is adhered, and a wall sheet in which a transparent sheet coated with a metal and a transparent sheet coated with a colorant are mixed have been proposed.

However, this wall sheet still has a drawback. That is, the wall sheet is kept in close contact by eliminating the air layer between the transparent sheets. However, when vapor deposition or printing is performed on the lower surface of the olefin film, the surface becomes rough and the electrical characteristics are changed, and the adhesion of the lower transparent sheet to the PET film is deteriorated. If an adhesive is used instead of the air layer elimination in order to solve this difficulty, when the transparent sheet is peeled off, the vapor deposition and the coloring agent partially remain on the lower transparent sheet, which significantly impairs the appearance. Become. Therefore, in practice, evaporation or printing is limited to the lower surface of the PET film. In this case, if the entire surface is vapor-deposited, since the vapor-deposited surface of each transparent sheet appears on the surface, even if the old transparent sheet is turned, no change occurs. Also, when a colorant is applied, the color of the lower transparent sheet can be seen through, and it is difficult to determine what is being displayed.

[0006]

The present invention has been completed as a result of intensive studies to develop a wall decorative sheet which does not cause such defects. Hereinafter, the decorative wall sheet of the present invention will be described in detail.

[0007] The decorative wall sheet of the present invention includes a printed polyethylene terephthalate film (hereinafter referred to as a printed PET film) having one or more surfaces printed thereon, and a metal deposited on a part or the entire surface of one surface. A metallized polyethylene terephthalate film (hereinafter, referred to as a metallized PET film) to which a metal foil is adhered is adhered in a state where a printed surface and a metal surface are opposed to each other to form a picture sheet, and a plurality of the picture sheets are printed PET film. Are laminated so as to be peelable in a state where they are on the upper side, and an adhesive is applied to the back surface of the lowermost pattern sheet and is backed with release paper.

That is, in the conventional wall sheet described above, when viewed from the release paper side, the printed PET film is printed on the lower surface side, and the metallized PET film is subjected to metal deposition or metal foil bonding on the upper surface side. ing. Therefore, the pattern sheet of the present invention is a film surface on both the front and back surfaces, and even if the pattern sheets are laminated so that they can be peeled off with an adhesive or the like, the vapor deposition or printed portion at the time of peeling remains on other pattern sheets. Not at all. In addition, since the lower surface of each of the design sheets is a metal surface, the print of the lower design sheet cannot be seen at all. Then, only the printing on the upper surface side is clearly visible.

The metallized PET film is generally metallized on one side of the film, but may be partially metallized in some cases. For example, in the case of stacking a plurality of pattern sheets, if the part with the upper part of the pattern sheet is made transparent and the characters and figures provided on the lowermost pattern sheet can be seen through, the corresponding part of the upper layer Requires a part that is neither printed nor deposited.

[0010] In the wall decorative sheet of the present invention, in addition to the above-mentioned pattern sheet in which the printed PET film and the metallized PET film are bonded, a pattern sheet in which a polyolefin film (hereinafter, referred to as a PO film) is further bonded to one surface thereof. Can also be used. In this case, one side of the picture sheet is a PET film and the other side is a PO film,
The close contact state can be maintained by eliminating the air layer between the picture sheets.

The printed PET film constituting the present invention is:
Using a polyethylene terephthalate film having a thickness of 5 to 50 μm, more preferably 6 to 38 μm,
It is printed with offset, flexo, silk, etc. The thickness of the printing layer is about 1 to 5 μm. The metallized PET film of the present invention has a thickness of 5 to 50.
A polyethylene terephthalate film of μm, more preferably 6 to 38 μm is used, and a metal such as aluminum is vapor-deposited or sputtered. The thickness of the metal layer is about 300 to 800 °. Or, the thickness is 5
Dry or wet laminated metal foil (eg, aluminum foil) of about 30 μm may be used.

The picture sheet of the present invention is obtained by bonding the printed PET film and the metallized PET film such that the printed surface and the metal surface face each other. Adhesion is performed by dry lamination using an adhesive or a polyethylene layer (10 to 20).
μm). Then, a plurality of the picture sheets (about 2 to 5 sets) are releasably laminated in a state where the printed PET film comes to the upper side, and
An adhesive is applied to the back surface of the lowermost pattern sheet and backed with release paper to finish the wall decorative sheet.

The lamination of the pattern sheets is usually performed using an adhesive. In this case, if the adhesive strength is too strong, it will be difficult to peel off, and if the adhesive strength is too weak, it will be carelessly rolled. Further, for example, when three sets of pattern sheets are laminated, the first set and the second set of the adhesive are applied to the second set and the third set.
Use of an adhesive having a lower adhesive strength than the adhesive of the set has an advantage of preventing the second set of picture sheets from peeling off when the first set of picture sheets is peeled off. In order to facilitate peeling of the picture sheet, it is preferable to provide a portion without an adhesive at a corner or the like, or to provide an ear for assisting peeling.

For lamination of the pattern sheets, a polyolefin film is adhered to one side of the pattern sheet, and the polyolefin surface is overlapped with the polyethylene terephthalate surface of another pattern sheet and pressurized to form an air layer between the pattern sheets. Elimination methods are also possible.

[0015]

Next, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of a picture sheet used in the present invention, and FIG. 2 is a cross-sectional view showing an example of a wall decorative sheet on which the picture sheets are laminated. The pattern sheet 1 is obtained by dry-laminating a printed PET film 2 and a metallized PET film 3 with the printed surface and the metal surface facing each other with an adhesive 4. Therefore, the picture sheet 1 of the present invention is characterized in that the printed surface clearly appears when the printed PET film 2 side is turned up, and that even when a plurality of the picture sheets 1 are stacked, the lower picture is not seen at all. In addition, since the front and back surfaces are the polyethylene terephthalate film itself, there is no fear that the printing ink layer or the metal vapor deposition layer will be peeled off when the picture sheet 1 laminated with the adhesive is peeled off. Note that the printed PET film 2 of this example has a thickness of 12
A printing 22 is applied to one side of a polyethylene terephthalate film 21 of about μm, and the metallized PET film 3 is formed by depositing an aluminum metal layer 32 on one side of a polyethylene terephthalate film 31 of about 25 μm in thickness.

The decorative wall sheet 5 of the present invention is obtained by laminating a plurality of sets (three sets, 1a, 1b, and 1c in the figure) of the picture sheets 1 and backing them with a release paper 6. The picture sheets 1 are laminated so that the printed PET film of the picture sheet can be peeled off by the adhesive 7 having a low adhesive strength. In this case, if the adhesive 7a on the upper side has a lower adhesive strength than the adhesive 7b on the lower side, the pattern sheet 1 can be peeled off satisfactorily. Further, a stronger adhesive 8 is applied to the back surface of the lowermost pattern sheet 1 c and is backed with a release paper 6.

In using the wall decorative sheet 5, the release paper 6 is adhered to the wall while gradually peeling off. As a result, 3 walls on the kitchen and other walls and the inner wall of the elevator
The set (three layers) of the picture sheets 1 are fixed together.
When the topmost picture sheet 1a is dirty or damaged, or when one wants to get tired of the picture or to give a sense of the season, peel off the picture sheet 1a and remove the second set (second sheet) of the picture sheet 1b. Put on the table. Similarly, when the time comes, the picture sheet 1b is peeled off, and the third (third) picture sheet 1c is exposed. The picture sheets 1a, 1b and 1c may be of the same design or color, but it is better to change the color or the design to give a change.

When the entire surface of the metallized PET film 3 is metallized, the picture sheet of the lower layer cannot be seen at all. In this case, if the printing is partial, only the metal surface is visible at the unprinted portions. On the other hand, if some metallization is not used, especially printed PET
When the corresponding portion of the film 2 is not printed, the printed surface or the metal surface of the pattern sheet 1 under the film 2 can be seen through. Therefore, as shown in FIG. 3, a sign 9 such as "Beware of Fire" is printed on the third set of pattern sheets 1c, and the entire surface is metallized.
If printing or metallization is not applied to the corresponding portions 10a and 1b, a sign such as a precautionary note or a slogan is always visible in any of the picture sheets 1.

A picture sheet 11 shown in FIG. 4 is obtained by bonding a polyolefin film 12 with an adhesive 13 to one side, for example, the back side of the above-mentioned picture sheet 1. Therefore, the picture sheet 11 is made of a polyethylene terephthalate film having one side hard and a polyolefin film having a high flexibility on the other side.
When the air gap between the picture sheets is eliminated by pressing the pieces 1 together, the two adhere to each other and the picture sheets 11 can be laminated without using an adhesive. FIG. 5 shows a wall surface decorative sheet 14 in which three sets of the picture sheets 11 are stacked. Others are the same as FIG.

[0020]

As described in detail above, the decorative wall sheet of the present invention has a printed P on one or more of which is printed.
An ET film and a metallized PET film in which a metal is vapor-deposited on one side or a whole surface or a metal foil is bonded,
A printed sheet is adhered with the printed surface and the metal surface facing each other to form a picture sheet, and a plurality of the picture sheets are peelably laminated with the printed PET film on the upper side, and adhered to the back of the lowermost picture sheet. An agent was applied and backed with release paper.

Accordingly, since the lower surface of each pattern sheet is a metal surface, the printing of the other lower pattern sheet cannot be seen at all, and only the printing on the upper surface can be clearly seen. Each pattern sheet is not affected by other pattern sheets at all, so each pattern sheet is expressed in different colors with patterns representing the four seasons or the same pattern, even if the surface is dirty or not dirty The lower picture sheet can be turned up periodically so that the lower side of the picture sheet can be exposed, and the pattern change in the room or the inside of the elevator can be easily and reliably performed. Even if each picture sheet is laminated so as to be peelable with an adhesive or the like, vapor deposition and printed portions at the time of peeling are completely prevented from remaining on other picture sheets. And so on.
