In the figure, 1 is a printing paper (printing paper), 2 is an overcoat layer (protective laminating layer), 3 is a transparent film, 4 is an adhesive layer, 5 is a printed image, a character layer ( Hereinafter, it will be referred to as an image), and 8 is a description portion (hereinafter referred to as printing) of characters, patterns, symbols and the like printed on the protective laminate layer.

The print paper 1 is, for example, plain paper, and an image 5 is printed on the print paper 1 by a thermal transfer method or an electrophotographic method, and the image 5 can be visually confirmed on the print paper 1. A protective laminating layer (overcoat layer) 2 for protection is attached.
The protective laminate layer 2 is formed by applying an adhesive treatment such as an adhesive material or heat adhesion to the surface layers of the print paper 1 and the transfer image 5. The protective laminate layer 2 for performing such a laminating process is composed of a transparent film 3 and an adhesive layer 4.

The transparent film 3 has, for example, a thickness of several μm.
˜Several tens μm of PET (polyethylene terephthalate) or the like as a base, and the adhesive layer 4 has, for example, adhesiveness at room temperature, or an iron heated to a temperature of about 140 to 150 ° C. It is a material that generates adhesiveness when used and heated, and the adhesive layer 4 is applied to the surface of the transparent film 3 on the adhesive side.

The printed image 5 is formed by a thermal transfer system (or an electrophotographic system), for example, an ink made of a material in which a coloring pigment is mixed with wax or a resin material as a binder, and the thickness of the image 5 is
It may be about 5 μm or more.

As the wax or resin used as the ink raw material of the image 5, a material having a melting point such that the adhesiveness at the interface between the printing paper 1 and the protective laminate layer 2 becomes high and a wettability at the melting point temperature is selected. However, the internal adhesive force of the ink when the image 5 is formed must be set to be weaker than the adhesive force between the adhesive layer 4 and the image 5 and the adhesive force between the adhesive layer 4 and the print paper 1. As a result, as shown in FIG. 1A, for example, on the left side of the protective laminate layer 2,
If you peel it from the position of the dotted line to the position shown by the solid line,
In the image 5, the ink of the image 5 is internally destroyed while the protective laminate layer 2 and the print paper 2 are connected, and the image 5 is broken as indicated by A ₁ . In addition, as shown in FIG. 1B, when the operation of cutting out the print 1a on the lower side of the image 5 is performed, the image 5 has the same force relationship as in the case of FIG.
The ink is destroyed inside the ink as indicated by A ₂ . In this way, the image 5 is destroyed inside the ink and remains on the laminate layer 2 side, so it is impossible to forge or falsify the face photograph or the signature.

In addition, in an attempt to use the protective laminate layer 2 itself as a substitute, printing of characters, patterns and symbols 8 is performed on the joint surface of the protective laminate 2 which is joined to the print paper 1 as a preferable position. idea subjected, Ru can see through the easy to replace the protective laminate layer 2.

Since the thickness of the image 5 such as a facial photograph is several μm, light passes through the image 5. Therefore, if a pattern is printed or colored on the printing surface of the print sheet 1, the image 5 is affected by the pattern or color of the print sheet 1 and is difficult to confirm .

In the example of FIG. 4, by the method shown in FIG.
As shown in FIG. 4A, first, on the print paper 1,
After forming the hidden cover layer 7c, a character (c) such as "issued in Japan" is transferred onto the formed hidden cover layer 7c in a color different from the color of the hidden cover layer 7c, and then, On the letter (c),
Further, the hidden cover layer 7b is formed, and a number indicating the issue date such as 1994.08 is transferred with an ink of a color different from the color of the hidden cover layer 7b, and finally, the number (b) of the number is printed by the same method. A hidden masking layer 7a is formed on top of which a face image (a) is transferred and formed. As a finish, the protective laminate layer 2 shown by the dotted line is joined. Again, the adhesive strength between Lee ink, are weaker than the adhesive strength between the adhesive force or protective laminate 2 with the printed paper 1.

As described above, the cover layer 7c, the characters (c), ..., And the face photograph (a) are formed on the uppermost layer from the print paper 1 side to form a multilayer structure. , 7b, 7c
