Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to Braille label paper on which Braille is formed by a Braille printer.

[0002]

2. Description of the Related Art Braille label paper uses a Braille printer to print protruding Braille on the surface, and then peels off the release paper temporarily attached to the adhesive layer on the back surface, and applies it to adherends such as various articles. It can be used for visually impaired people by attaching it.

As a base material of such Braille label paper, a paper base material made of high quality paper is generally used. The paper base material has the advantage of good braille moldability by a Braille printer and the ability to print normal characters that can be read by healthy persons, but is inferior in durability and water resistance and needs to be frequently replaced. . Therefore, when durability and water resistance are required, Braille label paper made of a synthetic resin having a vinyl chloride film as a base material has been used.

[0004]

By the way, the above-mentioned substrate made of a vinyl chloride film is suitable for forming Braille by a Braille printer because it has a suitable extensibility and rigidity, but it is incinerated as garbage after use. Then, dioxin is generated, which is not preferable from the viewpoint of environmental problems.
In addition, if normal characters are poor in printability and normal characters that can be read by healthy persons are also required to be displayed, normal characters are separately printed on paper label paper and converted to braille formed with braille. It had to be attached to the adherend together with a vinyl film label.

[0005] Therefore, polyethylene terephthalate (hereinafter, referred to as a synthetic resin base material instead of a vinyl chloride film).
This is abbreviated as “PET”. ) Attempted to use film. As shown in FIG. 7A, a Braille label is formed by forming an adhesive layer 5 on the back surface of a PET film layer 2 having the same thickness as a conventional vinyl chloride film, and applying a release paper 6 to the adhesive layer 5. When the Braille label paper a is printed with Braille using a Braille printer, the PET film layer 2 is harder than the vinyl chloride film. Meanwhile, when the pin 8 is pressed from the release paper 6, the PET film layer 2 is not deformed in the shape of the pin 8, and the entire area around the compression point is peeled off from the release paper 6 to be lifted. Therefore, the convex Braille 9 formed on the surface of the PET film layer 2 becomes low. That is, as shown in FIG. 3A, when the pin 8 is pressed, the pin 8 acting on the PET film layer 2 via the release paper (not shown) is pressed against the hard PET film layer 2. It is considered that the pressure transmission efficiency is low because the top of the pin 8 is in point contact, and the PET film layer 2 cannot be deformed according to the shape of the pin 8.

[0006] The present invention solves such a conventional problem,
It is an object of the present invention to provide a Braille label sheet that can form Braille of an appropriate height on the surface of a PET film layer by a Braille printer.

[0007]

According to the present invention, there is provided a pressure-sensitive adhesive layer formed on a back surface of a PET film layer with a deformation auxiliary layer made of paper, nonwoven fabric, styrene resin or the like, and further formed on the back surface of the deformation auxiliary layer. Is a braille label paper characterized in that a release paper is adhered to the surface of the PET film layer, and a convex braille is formed on the surface of the PET film layer by a pin pressing force from the release paper side.

In this configuration, since the deformation assisting layer is bonded to the back surface of the PET film layer, when the braille printing is performed by pressing with a pin from the release paper side, the pressing force of the pin is easily deformed. It is efficiently transmitted to the PET film layer via the deformation assisting layer, so that a convex Braille with an appropriate height can be formed on the surface of the PET film layer.

In the above-mentioned structure, there may be proposed a structure in which a coating layer having excellent printability of ordinary characters is formed on the surface of the PET film layer. By printing normal characters on this coating layer, the PE that forms Braille
Normal characters that can be read by healthy persons can be written in parallel on the surface of the T film layer.

Further, in the above structure, the PET film layer has a thickness of 25 to 100 μm, and the deformation auxiliary layer has a thickness of 70 to 100 μm.
A preferred embodiment can be proposed as a preferred embodiment in which the total thickness is 160 to 320 μm including the thickness of the release paper and the thickness of necessary constituent layers such as an adhesive layer. This achieves a predetermined thickness that can be used in a Braille printer that forms Braille with a pin pressing force from the back side.

In the above structure, it is possible to propose a structure in which the deformation auxiliary layer is made of a styrene resin and the deformation auxiliary layer and the PET film layer are transparent. Thereby, since the lower surface side of the deformation assisting layer can be seen through from the surface side of the PET film layer, when a Braille label formed with Braille is adhered to an adherend such as various articles, it is displayed on the adhered surface. This makes it possible to visually recognize the information such as the characters that are present.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a Braille label sheet according to the present invention will be described below with reference to FIGS.
As shown in FIG. 1, the Braille label paper 1 has a deformation auxiliary layer 4 made of paper, nonwoven fabric, styrene-based resin, etc., integrally bonded to the back surface of a PET film layer 2 via an adhesive layer 3. Further, a release paper 6 is adhered to an adhesive layer 5 formed on the back surface of the deformation assisting layer 4. On the release paper 6, a release agent layer 7 containing silicon is formed on the surface to be adhered to the adhesive layer 5, so that the release agent layer 7 can easily peel off from the adhesive layer 5.

The PET film layer 2 has a thickness of 25 to 1
A PET film having a thickness of 00 μm is preferably used, and the deformation auxiliary layer 4 is made of high-quality paper such as high-quality paper, recycled paper, kenaf-containing paper, etc. having a thickness of 70 to 150 μm, which is easily deformable and has excellent braille formability, or an appropriate cushioning property And a styrene-based resin that is easily deformed and easily deformable, has excellent moldability in Braille, and has an appropriate cushioning property. Examples of the styrene resin include polystyrene, polymethyl methacrylate (PMMA), methyl methacrylate styrene copolymer (MMA-St copolymer), and acrylonitrile styrene copolymer (AS resin). Also,
The deformation auxiliary layer 4 made of such a styrene resin and the P
The ET film layer 2 may be made of a transparent material. In this case, a transparent material is also used for the adhesive layer 3 and the adhesive layer 5. Then, the total thickness of the Braille label paper 1 obtained by adding the thickness of the release paper 6 and the thicknesses of required constituent layers such as the adhesive layer 3, the adhesive layer 5 and the release agent layer 7 to the PET film layer 2 and the deformation auxiliary layer 4. Is set to 160 to 320 μm, whereby the predetermined thickness can be used in a Braille printer that forms Braille by pressing a pin from the back side.

Then, the Braille label paper 1 having the above-described configuration was prepared, and Braille was printed from the release paper 6 side using a Braille printer. As shown in FIG. It was confirmed that the convex Braille 9 having an appropriate height was formed on the surface of the PET film layer 2 without the periphery of the PET film layer 2 being lifted off from the release paper 6. This is because, as shown in FIG. 3B, when the pin 8 is pressed through a release paper (not shown), the deformation assisting layer 4 bonded to the back surface of the PET film layer 2 has the shape of the top of the pin 8. Deformed according to
Since the pressing force applied to the ET film layer 2 acts in a dispersed state due to the surface contact of the top of the pin 8, the pressing force is transmitted efficiently, and the PET film layer 2 is deformed according to the shape of the pin 8. It seems to be.

Then, the braille label paper 1 on which the braille 9 is formed as shown in FIG.
It is used for visually impaired people by sticking it to adherends such as various articles, etc., but it is excellent in water resistance because the PET film layer 2 is disposed on the Braille label paper 1 In addition, the durability that the formed Braille 9 is not easily deformed even when the Braille 9 is touched with a finger is obtained.

In particular, when the deformation assisting layer 4 is made of a styrene-based resin, the styrenic resin is excellent in braille moldability like paper and has cushioning properties like nonwoven fabric. However, since the rigidity is higher than that of paper or nonwoven fabric, the strength of the formed convex Braille 9 is improved, and the durability is further improved.

The deformation assisting layer 4 and the PET film layer 2
Is transparent, the lower surface side of the deformation assisting layer 4 can be seen through from the surface side of the PET film layer 2, so that the characters displayed on the adhered surface in the state of being adhered to the adherend Etc. can be visually recognized. Thereby, for example, by attaching a transparent braille label formed with Braille to an adherend such as a restaurant menu, a healthy person can use normal characters displayed on the attachment surface, and a visually impaired person can use braille. It is possible to know the display information.

FIGS. 5 and 6 show a second embodiment of the Braille label paper 1 in which a coating layer 10 having excellent printability of ordinary characters is formed on the surface of a PET film layer 2. It is. The coating layer 10 can be formed by providing a porous layer containing clay or calcium carbonate on the PET film layer 2. Other configurations are the same as those of the first embodiment, and the same portions are denoted by the same reference numerals, and redundant description will be omitted.

As described above, by forming the coating layer 10 having excellent printability of normal characters on the surface of the PET film layer 2, a Braille printer having a function of printing normal characters on the coating layer 10 can be provided. Since normal characters can be printed using the normal characters, if normal characters that can be read by healthy persons are also required to be displayed, the normal characters are not separately printed on a paper label sheet as in the related art. As shown in the figure, the normal characters 11 can be written in parallel with the formation of the braille 9.

[0020]

As described in detail above, according to the present invention,
Since the deformation assisting layer is bonded to the back surface of the PET film layer, a convex braille of an appropriate height can be easily formed on the surface of the PET film layer by the deformation assisting action of the deformation assisting layer.

Also, by forming a coating layer having excellent printability of ordinary characters on the surface of the PET film layer, ordinary characters can be printed on the coating layer, and the PET film layer on which the Braille is formed can be formed. On the surface, normal characters can be written in parallel, which can be read by healthy persons.

Further, the PET film layer has a thickness of 25 to 1
00 μm, the thickness of the deformation auxiliary layer is 70 to 150 μm, and the total thickness including the thickness of the release paper and the thickness of the necessary constituent layers such as the adhesive layer is 160 to 320 μm to constitute the Braille label paper, so that A predetermined thickness that can be used in a Braille printer that forms Braille with a pin pressing pressure is realized.

Further, by making the deformation assisting layer a styrene-based resin and making the deformation assisting layer and the PET film layer transparent, a Braille label is attached to an adherend on which information such as characters is displayed. In this case, there is an excellent effect that information on the sticking surface can be visually recognized.
