Abstract

PROBLEM TO BE SOLVED: To turn a metallic gloss section into black and discriminate a fake from a genine in the case an original commuter pass is duplicated by a color copier by forming a metallic gloss face at least on a part of a printed face on the surface and laminating a shading printed layer and a printed layer on the metallic gloss face in the above-said order. SOLUTION: The printing section side of a commuter pass 20a is constituted of the lamination of a deposit anker layer 5, a metallic deposit layer 6, an image receiving layer 2, a shading printed layer 3 and a printed layer 4 on a base 1 in the above-said order. In the constitution of the layers, first the deposit anker layer 5 for generating metallic gloss is coated with epoxy acrylate ultraviolet curing type resin of thickness of approximately 1μm on the base 1 and cured thereon. Then the metallic deposit layer 6 is formed on the surface, and then polyester resin is applied to form an image receiving layer 2. Then a shading printed layer 3 is formed on the image receiving layer 2, and the display information such as the required effective period of time, names and the like is printed from over the shading layer 3 by a transfer printer to form the printed layer 4.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a commuter pass having a function of preventing falsification and forgery using a color copying machine.

[0002]

2. Description of the Related Art In recent years, banknotes that must have been subjected to advanced counterfeit prevention measures due to technological advances in color copiers,
Counterfeit securities such as gift certificates, invitation tickets, and cards have become available, which has become a social problem. The commuter pass is also subject to falsification and forgery of the expiry date, and the copy-forgery-inhibited pattern printing has been conventionally adopted as a preventive measure. This is tampering with the printed characters by printing on the tint block,
This is because the alteration is difficult. The commuter pass is roughly classified into a printing method and a resin commuter ticket and a wax commuter ticket.
The resin-based commuter pass has a clear ink image layer on the surface, and the characters that should be displayed are printed using a resin-based transfer ribbon. The wax-based commuter pass uses an ink image-receiving layer with a matte surface, and a wax on top of this. It is printed using the system transfer ribbon. FIG. 1 is a schematic sectional view of a conventional resin-based commuter pass. An image receiving layer 2, a tint block printing layer 3, and a printing layer 4 are formed on the front side of a substrate 1, and a magnetic recording layer 7 and a protective layer are formed on the back side of the substrate 1. 8, a print layer 9 for the description and the like is formed.

However, the tint block, which has been used on the entire surface of the commuter pass, is printed finely using a special light color, but the resolution is high today. However, since it can be easily reproduced by a color copier having good color reproducibility, there is a problem that the tampering and forgery prevention function is weakened. In addition, if you copy a commuter pass with a copy check pattern printed with a tint block, potentially hidden warning characters and patterns will become visible, and you can easily visually identify that the copy is a copy. It has the effect of restraining counterfeiting and counterfeiting, but as the resolution of copiers further improves in the future, its reproducibility also improves,
The anti-counterfeiting effect is expected to diminish. The printing of the restraint pattern requires a high-precision plate making and printing technique for controlling the thickening and thinning of halftone dots, and there is a problem that the printing cost becomes high. The present invention has been made in view of the above-mentioned problems, and it is possible to easily determine that the copy is a copy only by visual inspection, and moreover, it is possible to easily perform the printing by the conventional state of the art, and it is possible to prevent falsification and forgery. The purpose is to provide a certain commuter pass.

SUMMARY OF THE INVENTION The present invention, which has been made to solve the above-mentioned problems, provides a metallic glossy surface on at least a part of a printed surface, and a tint block printing layer and a printing layer are formed in this order on the metallic glossy surface. The idea is to stack on the surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 2 is a diagram for explaining the principle of preventing forgery of a commuter pass according to the present invention. As shown in FIG. 2, the color copying machine employs a system in which light is emitted from a light source at an angle of 45 ° with respect to an original and the intensity of reflected light is read by a light receiving portion substantially directly below the original. FIG. 2A shows a case of a conventional commuter pass, in which light is scattered on the surface of the original and reflected light reaches the light receiving portion as in the case of a general original, and the intensity of the three primary color components is measured. The corresponding gradation and color tone are reproduced. However, when the screen has a metallic glossy surface, as shown in FIG. 2B, the illumination light is specularly reflected by the metallic glossy surface, and the reflected light hardly reaches the light receiving portion. Reproduced as black. When looking at printed matter with a metallic glossy surface under general lighting, it is rare that all the light reaches the eye because the light illuminates the printed matter from each direction, and rather the amount of light that enters the eye due to specular reflection is rather rare. Most of them, therefore, appear to shine with a so-called metallic luster. This shining part turns black in the copy, so
The degree of change is large, and the difference is obvious to anyone, and the tampering effect of the metallic glossy surface, the counterfeiting effect of counterfeiting,
Some preventive effects are extremely large.

As a method for giving at least a part of the commuter pass a metallic luster, the metallic thin film layer may be directly formed by vacuum vapor deposition, sputtering or the like of various metals, or the metallic thin film may be once formed on the transfer laminate. However, this layer may be transferred to the commuter pass through the adhesive layer.

FIG. 3 is a schematic sectional view showing the structure of an embodiment of a commuter pass according to the present invention. FIG. 3A shows Example 1 in which the printed surface of the commuter pass has a metallic luster, and the printed part side of the commuter pass 20a has a vapor deposition anchor layer 5 and a metal vapor deposition layer 6 on the base material 1. The image receiving layer 2, the tint block printing layer 3, and the printing layer 4 are laminated in this order. Since the back side of the base material 1 is the same as the conventional one, the description is omitted. A specific method of forming the layer structure on the front side of the substrate 1 in Example 1 will be described with reference to FIG. First, the base material 1 has a luster and is excellent in dimensional stability with an opalescent polyethylene terephthalate sheet (Lumirror E-20, manufactured by Toray Industries, Inc.), 1
88 μm was used. On the base material 1, a vapor deposition anchor layer 5 that imparts smoothness to the vapor deposition surface and gives a metallic luster is coated with an epoxy acrylate-based UV curable resin in a thickness of 1 μm,
It was formed by curing. Next, aluminum vapor deposition was performed on the entire surface of this smooth surface to form a metal vapor deposition layer 6 having a thickness of 500 Å. An image receiving layer 2 was formed by coating the metal vapor deposition layer 6 with a polyester resin in a thickness of 1 μm. This is to improve the adhesion of the print layer with the tint block printing ink and the transfer ribbon. Next, a tint block print was performed on the image receiving layer 2 by gravure printing to form a tint block print layer 3. Urethane-based gravure ink was used as the ink. Display information such as the effective period and name required for the above laminated body was printed on the copy-forgery-inhibited pattern layer 3 by the transfer printer to form the printing layer 4, and the commuter pass 20a according to the present invention was obtained.

Next, the configuration of the second embodiment shown in FIG. 3b will be described. In Example 2, the metallic glossy surface was partially formed, and the metal vapor deposition layer 6 was partially formed on the vapor deposition anchor layer 5. Other than that is the same as that of the first embodiment.
FIG. 4 shows an example of a partial metallic luster pattern, and the pattern applied to the commuter pass according to the present invention may be arbitrarily selected. In addition to these, an independent shape pattern may be repeatedly arranged at a certain pitch, or a continuous pattern or the like. In Example 2, a striped pattern was used. Various methods can be adopted as the method of forming the pattern. For example, in the case of a striped pattern, a shield plate (mask) having an opening with a predetermined width may be placed close to the vapor deposition anchor layer 5 to be vapor deposited.
If a block-shaped pattern or an arbitrary shape pattern is used, the method of the third embodiment described below may be adopted.

FIG. 3C shows the configuration of the third embodiment. The third embodiment has a metallic glossy surface partially like the second embodiment, but the shape is a square block shape, and the forming method is different, and the metal transfer vapor deposition layer 12 and the heat seal layer 11 are formed. In addition, it was formed by a method of peeling from the transfer paper and transferring to the base material 1 via the heat seal layer 11. A hot stamp provided with a heating plate having a quadrangular convex portion was used when the metal vapor deposition layer 12 was transferred. It is possible to obtain a metallic luster portion having an arbitrary shape depending on the processing of the convex portion.

In order to improve the adhesive strength between the layers of Examples 1 to 3 described above, a primer layer is provided between the layers indicated by A, if necessary, particularly in FIGS. 3 (a) to 3 (c). be able to.

The higher the reflectance of the metallic glossy surface formed as described above, the smaller the amount of light received by the light receiving portion shown in FIG. 2C, and the metallic glossy surface is reproduced in black, which is ideal. Reflectivity of 45% incidence, vertical light reception is 20%
It is preferably less than 10% and more preferably less than 10%. When this reflectance is 30% or more, the metallic glossy surface is reproduced in a light gray color, and the difference from the real one disappears.

The commuter passes 20a to 20c according to the present invention obtained in the above Examples 1 to 3 were copied by using a color copying machine (Canon "PIXEL DIOS"). It was less than, and was copied in dark black, and a copy completely different from the commuter pass visually observed was obtained. This is different from the real thing at first glance and can be visually judged by anyone, and even if the printed character is tampered with on the copy, even if it is forged, the surrounding area is blackened, so there is no method for tampering, The effect of preventing forgery is great. Particularly, it is particularly effective when a solid metallic gloss surface is provided over the entire surface of Example 1 or when a metallic gloss pattern is provided over the entire surface. It should be noted that no significant difference was observed between the examples in the degree of blackening due to the pattern of the metallic glossy surface.

[0013]

According to the present invention, even if an attempt is made to copy a genuine article by a color copying machine and copy it, the metallic glossy portion is blackened and copied, so that anyone can at first glance identify it as a fake article. Since the periphery of the printed characters is also blackened, tampering and forgery in the copy is difficult, and the effect of tampering and forgery is demonstrated.
