As described in JP-A-36493, in a state in which two transparent resin films each having a heat-sensitive adhesive layer formed on one surface thereof are overlapped with each other on the other surface and bonded with a heat-sensitive adhesive, the postcard paper is folded. It is sandwiched between two confidential surfaces facing each other, and one side of each is thermocompression-bonded to the confidential surface by a heat-sensitive adhesive layer to complete. Then, when opening the confidential postcard, the transparent resin films adhered by the anchoring force weaker than the anchoring force for the postcard paper are peeled from each other, so that the confidential faces are peeled off, and each confidential face is transparent. The resin film is left to be adhered.

している。However, the process of laminating two transparent resin films having a heat-sensitive adhesive layer formed on one side thereof and pasting them together with a heat-sensitive adhesive is very troublesome, and the processing cost is also high. It had the drawback of being bulky. Also,
When the two transparent resin films as described above are wound into a roll and stored, the heat-sensitive adhesive layers formed on one surface of each film are in close contact with each other and overlap each other. There is a risk that the adhesive layers may block each other and the film may not be unwound. Further, since the confidential postcard in which the two transparent resin films as described above are sandwiched between the two confidential surfaces of the postcard paper can only be produced one by one in sequence, the productivity is very poor.
Therefore, it is a technical object of the present invention to use only one transparent resin film having a heat-sensitive adhesive layer formed on one surface so that confidential postcards can be mass-produced by simple processing.

する。In order to solve this problem, the present invention is completed by folding a postcard sheet so that two adjacent confidential surfaces are faced to each other, and the confidential surfaces are pseudo-adhered so as to be peelable from each other. In a confidential postcard, a transparent resin film with a heat-sensitive adhesive layer formed on one side is thermocompression-bonded by the heat-sensitive adhesive layer so as to cover two adjacent confidential surfaces of the postcard paper, and the two confidential It is characterized by being cut along the boundary of the surface.

As a result, it is divided into a half body thermocompression-bonded to one confidential surface and a half body thermocompressed to the other confidential surface. In addition, the heat-sensitive adhesive layer that thermocompresses the transparent resin film on the confidential surface of the postcard paper is superior in the anchoring force to the paper rather than the anchoring force to the resin film. The half of the resin film is peeled off and removed so as to be peeled from the heat-sensitive adhesive layer anchored to the confidential surface.

When one half of the transparent resin film thermocompression-bonded to one surface is thermocompression-bonded to one of the confidential surfaces with the thermosensitive adhesive layer anchored to one of the confidential surfaces, the two adjacent protective surfaces are transparent resin films. A peelable pseudo-adhesive postcard is completed between the heat-sensitive adhesive layer and the heat-sensitive adhesive layer.

Each of the postcard papers 1 used by folding in two is a roll of paper 4 or a sheet of paper on which two adjacent confronting surfaces 2 and 3 are arranged side by side in a two-page spread, or ethylene vinyl acetate copolymer resin on one side. , A heat roller comprising a transparent resin film 5 such as a polypropylene film or a polyester film having a heat-sensitive adhesive layer 6 formed by coating a hot-melt adhesive containing a polymer such as polyamide or polyurethane as a main component. Passing between 7 and 8, the film 5 is thermocompression bonded so as to cover the entire surface of the paper roll 4 or the sheet with the heat-sensitive adhesive layer 6 formed on one side thereof,
Cutting is performed by the cutter 9 along the boundary between the confidential surfaces 2 and 3 of the postcard sheets 1 that are adjacent to each other in the left-right direction when viewed from the feeding direction of the heat rollers 7 and 8. The transparent resin film 5 having the heat-sensitive adhesive layer 6 formed on one surface thereof is cut by cutting the roll-up paper 4 or the sheet according to the size of each postcard paper 1, as shown in FIG. A confidential postcard is obtained, which is thermocompression-bonded by the layer 6 so as to cover the two adjacent confidential surfaces 2 and 3 of the postcard paper 1 and cut so as to be divided into two along the boundary between the confidential surfaces 2 and 3.

キが完成する。When using this confidential postcard, the transparent resin film 5 thermocompression-bonded to the confidential surface 2 of the postcard paper 1 is used.
The half a is peeled off from the heat-sensitive adhesive layer 6 anchored to the confidential surface 2, and the postcard paper 1 is folded so that the confidential surfaces 2 and 3 face each other, and the postcard paper 1 is heated. Of the transparent resin film 5 thermocompression-bonded to the confidential surface 3 and then thermocompression-bonded to the confidential surface 2 with the heat-sensitive adhesive layer 6 anchored to the confidential surface 2. Two adjacent confidential surfaces 2 and 3 are peelably pseudo-adhered between the half b of the transparent resin film 5 and the heat-sensitive adhesive layer 6 of the confidential surfaces 2 and 3 to complete a confidential postcard.
