CONSTITUTION:The base sheet 1 is coated with a resin sheet 3 across an adhesive layer 2 except the right and left ends, and the information 4 is printed on the top surface of the resin sheet 3 in characters, symbols, etc. Then while the base sheet 1 and resin sheet 3 are folded into two along perforation 5 with the resin sheet 3 in, the opposite resin sheets 3 are heated and adhered in the separable state under pressure and a nonadhesion area 6 is formed in both internal surfaces of the opposite surfaces of the base sheet 1 along the edges. Consequently, even if water penetrates the base sheet 1 from the external surface to the internal surface, the penetration of the water is cut off by the resin sheets and the water does not reach the information display part, so that the information is protected.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention has information displayed inside and can be used for postal items such as postcards and sealed letters, business cards, other cards, books, catalogs, etc. Regarding the information stack that can be used.

[Conventional technology]

In Japanese Utility Model Application Publication No. 63-93175, transparent sheets are releasably adhered to each other, and on each side of the sheet opposite to the adhesive side, a sheet displaying concealed information to be kept confidential is attached. An invention related to a concealed information carrier characterized in that it is attached to an information display surface via an adhesive is disclosed. A similar device is also disclosed in Japanese Utility Model Application Publication No. 63-6870.

(Problems to be Solved by the Invention) In the conventional manufacturing of the above-mentioned concealed information carrying body, after the concealed information display step, a sheet with concealed information displayed on each side opposite to the adhesive surface of the see-through sheet is produced. The process of pasting the will continue. Moeya's information display process is easy to use even when the amount of processing is large.
This can be done instantly using a well-known printing system, such as a computer-linked printing system. However, since the latter process of attaching both sheets requires a large number of man-hours compared to the information display process described above, it constitutes a rate-limiting step in the manufacturing process of concealed information carriers, and if the amount of processing is large, concealed information This severely limits the body's manufacturing capacity.

In addition, if there is a defect in the pasting process of both of the sheets mentioned above, the value of the concealed information carrier as a product will decrease and it may become unusable as a postcard, etc. It becomes necessary to remanufacture including

In addition, since hidden information is inevitably disclosed in the above-mentioned two sheet pasting processes, if this process is outsourced to others, it is necessary to impose strict confidentiality obligations on those involved in the work, and Management becomes actually difficult.

Furthermore, even if the surface of the concealed information carrier is covered with a see-through sheet, if water or the like permeates from the outer surface to the inner surface of the sheet displaying the concealed information, the concealed information will become unreadable due to wetness. There is a possibility that it will happen.

The purpose of the present invention is to provide an information laminate and its information laminate that solves the problems of the conventional hidden information carriers, improves manufacturing capacity, reduces defective products, promotes confidentiality management, and improves water resistance. The purpose is to provide a manufacturing method.

[Technical Means for Solving the Problems and Their Effects] As set forth in claim 1, the information laminate according to the present invention has the side inner surfaces of opposing resin sheets releasably adhered, and at least one of the resin sheets. Information is displayed on the inner surface of the resin sheet, and a stand sheet is integrally provided on the outer surface of each resin sheet. Note that each sheet in the present invention includes the concept of a film.

The opposing resin sheets and the base sheets provided on their outer surfaces may be separated into single sheets in the information laminate, or may be continuously folded in two, three, or four. may be formed. The opposing resin sheets may be of different types. The information displayed on the inner surface of the resin sheet is not limited to information consisting of letters, numbers, symbols, etc., but includes, for example, pictures, patterns, figures, tables, frames, entry fields, ruled lines, etc., and is not limited to the display mode. There isn't.

In this information laminate, water that permeates from the outer surface to the inner surface of the base sheet is blocked by the resin sheet and does not reach the information display area. This information laminate can be peeled and developed from a suitable edge on the inner surface of the opposite resin sheet, and after development, the required information displayed on the surface of at least one resin sheet can be read. . The surface of the resin sheet after being developed may remain tacky or non-tacky depending on the adhesion mode of both resin sheets.

In the above, if the resin sheet also serves as the base sheet, there is no need to newly laminate the base sheet by selecting a resin sheet with an appropriate thickness.

Further, as described in claim 3, when the resin sheet is made transparent (including translucent) and information is displayed on the inner surface of the base sheet, the information on the base sheet is displayed through the resin sheet after the information laminate is developed. Since it can be read, certain information can be displayed separately on the base sheet and the resin sheet, and the information can be related to each other as necessary. The information displayed on the inside of the base sheet also
It is not limited to information consisting of letters, numbers, symbols, etc., but includes, for example, pictures, patterns, figures, tables, frames, entry fields, ruled lines, etc.

For example, as described in claim 4, information in an entry column formed by regular ruled lines, frames, etc. is displayed on the inner surface of the base sheet,
By displaying individual information that should fill the entry fields on the inner surface of the corresponding resin sheet, there is no need to display an entry field for each display of individual information, and after the information stack is developed, the individual information can be displayed in a fixed form. It can be read while inserted in the entry field.

Further, as described in claim 5, if one or more slits or perforations are formed on the edge at a depth reaching from the outer surface of the base sheet on one side to the inner surface of the resin sheet as necessary, the information The laminate can be easily peeled off from the slit or the like. When a plurality of slits or the like are formed, the information laminate can be easily peeled off by peeling and removing the band-like portion between the lines.

Furthermore, if a non-adhesive area is provided along the edge of the inner surface of the opposing base sheet, the information laminate can be easily peeled off from the non-adhesive area. The non-adhesive area may be formed, for example, by not locally covering the inner surface of one or both of the base sheets with the resin sheet, or by locally preventing adhesion between the resin sheets, one of the opposing resin sheets. Alternatively, it can be provided by locally adhering ink, paint, or other masking material to both inner surfaces by printing or the like. The non-adhesive area described in F may be provided along the edge, slightly inward from the edge; in that case, by appropriately cutting off the edge,
As before, the non-adhesive area will be exposed. Note that the non-adhesive area as recited in claim 6 can also be applied to the conventional hidden information carrying body as described above.

Furthermore, as described in claim 7, when both inner surfaces of opposing resin sheets are bonded along their edges so that they cannot be separated into separate layers, it becomes possible to peel them off after cutting the bonded portion.

The information laminate as described above, as set forth in claim 8,
A process of coating each base sheet with a resin sheet, a process of displaying information on the surface of at least one resin sheet, and a process of stacking both resin-coated base sheets so that each resin sheet faces each other and peeling off both resin sheets. It can be manufactured by a process of adhering to. Note that a cutting step may be added at an appropriate time if necessary.

The base sheet can be made of computer output paper or other paper materials, resin, ceramic, cloth, or a composite material thereof. The base sheet can be coated with the resin sheet by a well-known method. Information can be displayed on the surface of the resin sheet by handwriting, printing, printing with an ink ribbon or the like, transfer, photo development, or other methods. For handwriting, printing, printing, etc., inks that have excellent adhesion to the resin sheet, such as UV ink, silk screen ink, and solvent type ink, can be suitably used, and information can be transferred to the surface of the resin sheet. After displaying, ink drying and solidification steps are added as necessary.

Peelable adhesion of both resin sheets can be achieved, for example, through an adhesive layer or adhesive layer with weak adhesive strength, by applying pressure to the stacked resin sheets, or by applying pressure under moderate heating. can.

In the case of adhesion by pressure, resin sheets such as polyethylene, polypropylene, polyester, etc. can be suitably used. Another resin sheet, resin layer, drug layer, etc. may be interposed between the resin sheets as necessary.

Further, an antiblocking agent, a coupling agent, etc. may be added to the resin sheet, or a surface treatment such as plasma treatment, corona discharge, etc. may be performed. Information may be displayed on the surface of the resin sheet via another sheet or layer. The surface portion of the resin sheet on which information is displayed using ink or the like is not subjected to the pressure bonding described above, but the remaining surface portion to which no ink is applied is subjected to the pressure bonding.

In addition, the above-mentioned intermediate laminate in which information is displayed on the resin sheet and the information is displayed on the base sheet or not can be used as is or by interposing the information display surface on the resin sheet with the other resin sheet. By releasably adhering the other base sheet to the base sheet, it is possible to form an information laminate different from that of the present invention. Also, information regarding the present invention! A laminate with one base sheet removed can also be used as an information laminate other than the present invention.

In the case of the information laminate according to claim 2, the first step is omitted. In the case of the information laminate according to claims 3 and 4, a step of displaying required information on the surface of the base sheet is added before the first step.

Further, in the case of the information laminate according to claim 5, for example, a step of forming a slit or a perforation opening is added after the above-mentioned last step. In the case of the information laminate according to claim 6, a required non-adhesive area is provided, for example, during the first step and the intermediate step. Furthermore, in the case of the information laminate according to the seventh aspect, an adhesive layer that cannot be peeled off is provided by fusing, adhesive, or the like during the final step, for example.
