[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a record display paper, and more specifically, is attached to a wall or glass, etc.
The present invention relates to a recording display sheet mainly used as a display card or the like.

[0002]

2. Description of the Related Art In many cases, a display card is generally pasted through a glass of a wall or a show window. Some recent display cards can be pasted after word processing printing of characters and image information. Conventionally, an adhesive tape, a double-sided adhesive tape, glue, or the like has been used for sticking such recording display paper.

[0003]

[Problems to be Solved by the Invention] However, in the case of a display card simply pasted with glue or double-sided adhesive tape, the state of close contact with the bonding surface is not perfect. In some cases, the gloss of the portion changed, making it difficult to see. In addition, when the adhesive is peeled off, traces of the adhesive remain, and there is a problem in the cleaning process. Furthermore, the characters printed on the display card are relatively large enlarged characters, and if the ink ribbon cassette is used for such printing, there is a problem that the life of the ribbon is shortened and the printing cost is increased.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a recording and display sheet which has good adhesion to the surface of a wall, glass, or the like, has excellent removability, and can be easily printed.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a printing paper having a thermal transfer ink sheet on one surface, the ink surface of which is opposed to the printing paper, and a double-sided paper releasably bonded to the other surface of the printing paper. An adhesive sheet, comprising a protective sheet releasably bonded to the other surface of the double-sided adhesive sheet, provided with the adhesive material on both sides of the double-sided adhesive sheet in a dot-like or block-like discontinuous manner. The above object has been achieved by providing a recording and display sheet characterized by the following.

[0006]

According to the recording and display paper of the present invention, the recording and display paper can be set in a printer, characters and images can be displayed and printed on the printing paper, and then the protective sheet can be peeled off from the double-sided adhesive sheet. In this case, since no ink ribbon or the like containing a cassette is used, a clear display can be obtained at a relatively low cost. Further, if a plurality of types of ink application areas having different colors are provided on the thermal transfer ink sheet, multicolor printing can be easily performed by one printing.

Next, the protective sheet of the recording display paper is peeled off,
When the peeled adhesive surface of the double-sided adhesive sheet is attached to a wall surface or a glass surface, the above-mentioned adhesive material which is present discontinuously in the form of a dot or a block intervenes, so that no bubbles or the like enter between the surfaces to be attached. . For this reason, it can be stuck in a state of being almost completely adhered, and no distortion occurs on the printing paper and its display surface.

For this reason, paper is usually sufficient. As the thermal transfer ink sheet 5, 1 to 5 thermal transfer inks are applied to glassine paper or a heat-resistant film carrier of about 15 μ or less.
It is desirable to apply about μ, and examples of the film carrier include a polyethylene terephthalate film. Further, the size and shape of the ink sheet 5 may be substantially the same as those of ordinary printing paper, but are not particularly limited.

As the material of the double-sided adhesive sheet 2, any material may be used as long as it is particularly transparent and can apply an adhesive on both sides in a dot or block shape, and a sheet-like plastic film is suitable. is there. Specifically, a film or sheet of polystyrene, polypropylene, polyester, or the like can be used. The pressure-sensitive adhesive applied to both sides of the sheet has a point or block-like discontinuous coating surface having an area of 3 to 80 per 5 mm ^2.
%, Particularly preferably 10 to 60%.

The adhesive strength between the double-sided adhesive sheet 2 and the printing paper 1 or the protective sheet 3 is 180 ° peel adhesive strength of 300 gf.
/ 50 mm or less (measurement method: JIS Z 02)
37) In addition, it is desirable that a difference is provided between the adhesive strength between the double-sided adhesive sheet 2 and the printing paper 1 and the adhesive strength between the double-sided adhesive sheet 2 and the protective sheet 3.
Either the protective sheet 3 or the protective sheet 3 may be separated from the double-sided adhesive sheet 2 first.

The 180 ° peel adhesive strength between the double-sided adhesive sheet 2 and the wall or glass is 400 gf / 10 mm to 10 g.
The range of 00 gf / 10 mm is desirable, and it may have strong adhesiveness. In order to provide removability, 300 gf /
It is desirable that the thickness be suppressed to 10 mm or less, particularly 250 gf / 10 mm or less. As the pressure-sensitive adhesive 4, besides a natural pressure-sensitive adhesive, an ordinary pressure-sensitive adhesive such as an acrylic, urethane, rubber, eva, or olefin can be used. Also,
