2. Description of the Related Art In recent years, in the distribution industry, display labels such as shelf labels displaying product names, manufacturer names, prices, etc. have been widely used. Of these display labels, the one with a bar-shaped bar code printed is affixed to the product and the bar code displayed at the time of sale of the product is optically read, and the product name, price, etc. printed on the bar code. Information is input to a computer to be used for product sales, inventory management, etc., or in a factory that manufactures semiconductor parts etc. using an automated guided vehicle, it is used for destination command communication of the automated guided vehicle. ing. In such a label, when the printed bar code is optically read, the bar code is rubbed directly by the reading device, so that the bar code becomes dirty, becomes unclear, or if the bar code is composed of toner, The undesired situation such as the bar code being unreadable or erroneously read may occur due to stains on the reading device due to the falling off of the toner or a decrease in the print density. In addition, if characters, symbols, figures, etc. are still printed on the surface of the label for display, when used as a packing band, for example, the print on the surface may peel off due to contact or become unclear, or may be exposed outdoors. When used in, the printing may be discolored or peeled off due to wind, rain, sunlight, etc., resulting in a problem that the display function cannot be maintained for a long time. Therefore,
In order to solve such a problem, conventionally, in the information display sheet, the information recording surface is protected by a transparent resin film, and the information display surface is protected by the transparent resin film. As a method of manufacturing a sheet, generally, information is recorded on the surface of a base paper, which is provided with a release paper via an adhesive layer on the back surface, by an electrophotographic copying machine or printer, and then adhered to this information recording surface. A method of providing a transparent resin film via an agent layer is used. However, when a laminated paper in which a release paper is provided on the back side of the base paper via an adhesive layer is used in a copying machine or a printer, the adhesive adhered to the cut surface or the surface of the laminated paper is copied. Transferred to the photoconductor in the transfer section of the machine, etc., and then the toner adheres to the adhesive adhered to the photoconductor in the development section, which causes the background stain on the blank area of the information recording surface, so-called background fogging. The laminated paper has a three-layer structure, and when heated and pressed in a copying machine such as an electrophotographic copying machine, curling may occur and paper jam may occur, which causes an undesirable situation. To do.

[0003]

The present invention solves the problems of the prior art in such information display sheets, has good water resistance and weather resistance, and is excellent in long-term storage stability of recorded information. The present invention has been made for the purpose of industrially providing an information display sheet which is preferably used as a display label such as a shelf label used in the distribution industry.

[0004]

As a result of intensive studies to achieve the above object, the inventors of the present invention have found that a base paper on which information is previously recorded on a normal paper by an electrophotographic copying machine or printer. It was found that the objective can be achieved by laminating a transparent resin film on the information recording surface via an adhesive layer and a release sheet on the opposite surface via an adhesive layer. The present invention has been completed based on the above.

That is, according to the present invention, a transparent resin film provided with an adhesive layer is laminated on the information recording surface of a base paper on which necessary information is recorded in advance so that the adhesive layer contacts.
Further, the present invention provides an information display sheet in which a release sheet provided with an adhesive layer is laminated on the surface of the base paper opposite to the information recording surface so that the adhesive layer contacts. According to the present invention, the information display sheet, the information recording surface of the base paper in which the required information is previously recorded, the transparent resin film provided with an adhesive layer is arranged so that the adhesive layer is in contact, Then, a release sheet provided with an adhesive layer is arranged on the opposite side of the information recording surface of the base paper so that the adhesive layer is in contact, and pressure-laminated, and then information is recorded from the transparent resin film side. It can be manufactured by die cutting up to the base paper that has been prepared and carrying out desired imposition. Hereinafter, the present invention will be described in detail.

In the information display sheet of the present invention, it is necessary to use a base paper on which required information is recorded in advance. The type of the base paper is not particularly limited, and for example, paper generally used in electrophotographic copying machines and printers, or paper used for ordinary printing can be used. The method for recording the required information on these sheets is not particularly limited, and may be performed using, for example, an electrophotographic copying machine or printer, or may be performed by a normal printing method. In the information display sheet of the present invention, a transparent resin film is laminated on the information recording surface of the base paper on which information is recorded in advance in this manner with an adhesive layer, and a release sheet is laminated on the opposite surface with an adhesive layer. As the transparent resin film, for example, cellulose triacetate, cellulose diacetate, stretched polypropylene, cast polypropylene, high-pressure polyethylene, polystyrene, polycarbonate,
Films such as polyvinyl alcohol, soft polyvinyl chloride, polyethylene terephthalate and the like can be mentioned.

On the other hand, the release sheet is not particularly limited, and a commonly used release paper or the like can be used. This release sheet is usually subjected to a surface treatment such as a silicone resin treatment so that it can be easily released. The adhesive used for laminating the transparent resin film on the information recording surface of the base paper is not particularly limited, and either a pressure-sensitive adhesive or a heat-sensitive adhesive can be used, but it is easy to work. Pressure sensitive adhesives are preferred. This pressure-sensitive adhesive has the property of adhering by pressure without adhering in a normal state, and its base is not particularly limited. For example, an acrylic-based adhesive,
Any rubber type, polyvinyl ether type, or other type conventionally used for pressure-sensitive adhesives may be selected and used.

On the other hand, a pressure sensitive adhesive is usually used for the adhesive layer provided between the surface of the base paper opposite to the information recording surface and the peeling sheet. As this pressure-sensitive adhesive, the same ones as those described for the pressure-sensitive adhesive can be used. In the information display sheet of the present invention, if desired, a carrier sheet is provided on the opposite surface of the information recording surface of the base paper via an adhesive layer, and a release sheet is provided thereon via the adhesive layer. Good. In this case, a carrier sheet having an adhesive layer on both sides and a release sheet attached on one side may be laminated so that the adhesive layer contacts the opposite side of the information recording surface of the base paper. Further, the release sheet may be provided via two adhesive layers without providing the carrier sheet. Also in this case, the adhesive layer may be laminated so as to be in contact with the surface of the base paper opposite to the information recording surface, as described above.

In the production of the information display sheet, the order of laminating the transparent resin film and the peeling sheet is not particularly limited, and the transparent resin film may be laminated first, or the peeling sheet may be laminated first. Alternatively, the transparent resin film and the release sheet may be laminated at substantially the same time, but it is particularly advantageous to laminate the transparent resin film and the release sheet at the substantially same time on the base paper. Next, the production of the information display sheet according to the method of the present invention will be described. A base resin on which required information is recorded is prepared in advance, and a transparent resin film provided with an adhesive layer on the information recording surface of the base paper. Is placed so that the adhesive layer is in contact, and a release sheet provided with an adhesive layer is placed on the opposite side of the information recording surface of the base paper so that the adhesive layer is in contact, and pressure lamination is performed. To do. Next, the thus laminated materials are die-cut from the transparent resin film side to the base paper on which information is recorded, and desired imposition is carried out to obtain the information display sheet of the present invention.

In the method of the present invention, pressure-sensitive adhesives are usually used for the adhesive layer provided on the transparent resin film and the adhesive layer provided on the release sheet since they are laminated under pressure. Further, if desired, instead of the release sheet provided with the adhesive layer, a carrier sheet having an adhesive layer on both sides and a release sheet attached to one side may be used. When the information display sheet of the present invention is used, the release sheet is peeled off, the exposed adhesive layer is brought into contact with the product to be attached, and pressure is applied, whereby the information display sheet can be easily attached. Since the information recording surface of the information display sheet adhered in this way is protected by the transparent resin film, it does not become dirty, and since it has good water resistance and weather resistance, it can accurately display information over a long period of time. Can be displayed.
