The above-mentioned pseudo-bonded transparent sheets 9 and 1
It is preferable to use materials having low adhesiveness to each other as 1, for example, polyethylene terephthalate and polyethylene, polypropylene and polyethylene, polybutylene terephthalate and polyethylene, polyethylene terephthalate and polypropylene, polybutylene terephthalate and polypropylene, and other olefin-based materials. A combination of a resin and an ester resin or the like is suitable.

The pseudo adhesive layer 10 is formed by applying a resin having adhesiveness to one of the transparent sheets in a molten state between the transparent sheets 9 and 11 having low adhesiveness to each other so that the adhesiveness to the molten resin is high. It is only necessary to form a peelable pseudo-adhesive state with another low transparent sheet. More specifically, in the case of the transparent sheets 9 and 11 made of a combination of polyethylene terephthalate and polyethylene, these transparent sheets 9 and
It is possible to form by forming a resin of the same material as one film, for example, polyethylene by extrusion coating between 11 and laminating the respective transparent sheets 9 and 11.

Next, a procedure for creating a postcard in which the concealment information is covered and concealed using the concealment sheet 1 will be described. First, the target postcard will be described. As shown in FIG. 3, on the surface of the postcard 14, address information 15 indicating the destination and appropriate concealment information 16 such as a personal identification number and a deposit balance are printed. General transmission information 17 (see FIG. 5) that does not need to be hidden is printed on the back surface. Although not shown, this postcard 14 is also in the continuous state like the concealing sheet 1, and the above-mentioned printing is performed in the continuous state of the postcard 14
Is transferred in a predetermined direction by using the transfer hole, and is simultaneously printed using a printer linked with a computer.

With respect to the postcard 14 in such a continuous state, the concealment sheet 1 in the same continuous state is peeled off from the release liner 13 to expose the adhesive 12, and then the postcard 1
4 The back surface of the transparent sheet 11 is superposed on the front surface and adhered by the adhesive 12. Then, each marginal portion 4 is cut and removed from each perforation 3 for cutting, and further, each perforated sheet is cut at each perforation 2 for folding and cutting.

As a result, as shown in FIGS. 4 and 5, the address information 15 can be visually recognized through the transparent sheets 6, 9 and 11, while the concealment information 16 is a unit concealed by the non-transparent portion 7. It becomes a postcard 14 and can be mailed in the same manner as a normal postcard. The addressee who has received the postcard 14 in this state follows the guide 8 and sets the transparent sheet 6 together with the transparent sheet 9 from the pseudo adhesive layer 10 to the transparent sheet 11
On the other hand, when the postcard 14 is peeled off, the postcard 14 becomes in the state of FIG. 6, and the concealment information 16 can be visually recognized through the transparent sheet 11.

Next, a second embodiment will be described with reference to FIGS. 7 and 8. The concealing sheet 21 of the present embodiment is provided with cutting perforations 24 around the non-transparent portion 23 provided on the transparent sheet 22, and on the back surface of the transparent sheet 22 corresponding to the inside of the perforation 24 for cutting, Normally, it is not adhered, and it becomes possible to adhere when a predetermined pressure is applied. After the adhesion, a pressure-sensitive adhesive 25 that can be peeled off is applied, and the remaining part is not normally adhered, but adhered when a predetermined pressure is applied. Although it is possible, the pressure-sensitive adhesive 26, which is difficult to peel off after adhesion, is applied. The pressure-sensitive adhesive 26 may be appropriately selected and used from conventionally known pressure-sensitive adhesives. Although not shown, a guide text is printed at appropriate places on the transparent sheet 22 to break the cutting perforations 24 and peel off the non-transparent portion 23 of the transparent sheet 22.
