Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated card for immediate issuing.

[0002]

2. Description of the Related Art FIG. 4 is a diagram showing a conventional example of a laminated card. In a conventional laminated card 100, one end of polyester oversheets 102 and 103 is temporarily fixed to both sides of a card base material 101, and a face photograph 104 is formed on the card base material 101 or in a recess formed therein.
Place the holder display medium such as or name label 105,
The oversheets 102 and 103 were laminated on both surfaces of the card base material 101 by applying pressure or heat.
This laminated card has the advantage that it can be issued on the spot at the same time as enrollment, such as a membership card with a facial photograph. Moreover, since a holder display medium such as a facial photograph can be inserted, I
It is possible to have a D function.

FIG. 5 is a diagram showing a conventional example of a plastic card. On the other hand, the plastic card 200 is a card base material 201 made of vinyl chloride, and polyester oversheets 202, 203 previously laminated on the card base material 201.
A hologram layer 204 formed by vapor deposition of aluminum or the like is transferred and formed on the surface of the oversheet 202. Since this hologram 204 layer is difficult to manufacture, it has a card anti-counterfeiting effect and is transferred by applying a large pressure in order to provide a smooth surface.

[0004]

Since the former laminated card is used as a membership card of a sports club, there has been a demand for novelty and high-class design. In addition, because the laminated card has an ID function that the owner is the person who puts the face photograph, there is a possibility that it will be illegally used to replace the face photograph, so I want to have an anti-counterfeiting effect. There was a request. In the latter plastic card, the hologram layer is pre-transferred on the oversheet to provide the anti-counterfeiting effect. The layers could not be transferred.

An object of the present invention is to provide a laminated card which has novelty in design and a high-grade feeling, and has an anti-counterfeiting effect.

[0006]

In order to solve the above problems, a laminated card according to the present invention comprises a card base material (20) and a front side and / or one end of which is temporarily fixed to both sides of the card base material. And a backside oversheet (30, 10) on the card base material (41, 4).
In the laminated card in which 2) is arranged and the oversheets are laminated, a metal reflection hologram layer (11) is formed on a part or the entire surface of the oversheet.

[0007]

According to the present invention, since the metal reflection hologram layer is formed on a part or the whole surface of the oversheet, the three-dimensional effect is very well expressed, and the design is novel and high-grade. Since it is difficult to copy the metal reflection hologram layer, an anti-counterfeit effect can be obtained.

[0008]

The present invention will be described in detail below with reference to the drawings and the like. FIG. 1 is a view showing an embodiment of a laminated card according to the present invention, FIG. 1 is a perspective view seen from the front side, FIG. 2 is a perspective view seen from the back side, and FIG. It is a figure. The card of this embodiment is 2
A card base material 20 to which layer core materials are attached, a front side oversheet 30 and a back side oversheet 10 are temporarily fixed at their upper ends. A concave portion is formed on the front side of the card base material 20, and the face photograph 41 and the name label 42 are formed in the concave portion.
Is placed and the oversheets 30 and 10 are laminated.

As the oversheet 30 on the front side, the same conventional one is used, and as shown in FIG. 3, an adhesive layer 32 is formed on a base sheet 31. A magnetic stripe 33 is formed on the oversheet 30.

The backside oversheet 10 has a hologram forming layer 11 on the entire surface thereof, a surface protective film 14 formed on the hologram forming layer 11, and an adhesive layer 15 formed on the lower side of the hologram forming layer 11. It consists of and. The hologram forming layer 11 can be reproduced with white light.
A three-dimensional or three-dimensional image is recorded as a hologram image by, for example, a relief hologram method, and as a photographing method, for example, an image hologram, a rainbow hologram, a multiplex hologram, a computer-aided hologram, or a partially formed holographic image. Examples include gratings. Here, the computer-aided hologram refers to a hologram in which a plurality of computer graphics are photographed instead of photographing an actual object at the time of photographing so that a parallax is used to make the hologram look three-dimensional. Further, the hologram image does not necessarily have to be recorded by a holographic method, and a relief diffraction grating obtained by recording mechanically or by photolithography on a certain photosensitive material is partially formed. Things can also be used. Usually, embossed replicas of the relief shapes of these recordings can be used. The hologram image in this embodiment also includes a diffraction pattern formed by the diffraction grating as described above.

The hologram forming layer 11 is a hologram resin layer 12 having a relief surface of a hologram image formed on the lower surface.
And a reflective layer 13 formed on the relief surface of the hologram resin layer 12 for increasing the hologram effect. As the material for the hologram resin layer 12, a thermoplastic resin, a thermosetting resin, or a mixture thereof can be used. In addition, a moldable substance which has a radically polymerizable unsaturated group and is cured by heat and light or other radiation can be used. The hologram resin layer 12 is formed on the surface protection film 14 by a coating method or the like. If the surface protection film 14 can be embossed, a hologram image such as a relief hologram may be formed on itself. Well, in this case, the hologram resin layer 12 is unnecessary.

The reflective layer 13 is made of Al, Fe, Cr, Co,
It is a layer formed by forming a thin film of a metal such as Ni, Au, Ag or a metal compound by a method such as a vacuum deposition method, a sputtering method, an ion plating method, a plating method. The thickness is preferably 100 to 1000Å, more preferably about 500Å.

The surface protective film 14 is for protecting the hologram forming layer 11 from damage due to external force and for giving strength. The material of the surface protective film 14 is cellulose resin, polyimide resin,
Polystyrene-based resin, polyester-based resin, polyolefin-based resin simple substance, mixture, copolymer and the like can be used. The surface protection film 14 has a thickness of 5 to
About 200 μm is preferable. The surface protective film 14 may also serve as the hologram resin layer as described above.

The adhesive layer 15 is for laminating the hologram layer 10 on the surface of the card substrate 20, and in this embodiment, an acrylic resin, a vinyl resin, a polyester resin, a urethane resin, an amide resin. Adhesives such as epoxy resin, rubber resin, and ionomer resin can be used. The adhesive layer 15 has a thickness of 0.1 to 5
It may be about 0 μm, but 1 to 10 μm is preferable.

On the entire surface of the oversheet 10 on the back side,
Although the example in which the metal reflection hologram layer is provided has been described, it may be a part of the back surface, or at a position where the face photograph 41 and the name label 42 of the front oversheet 30 are not hidden.
It is also possible to form partially.

[0016]

As described in detail above, according to the present invention, the metal reflection hologram layer is formed on a part or the entire surface of the oversheet, so that the three-dimensional effect is very well expressed and the design is improved. You can get the novelty and luxury. Therefore, the card issuer can contribute to an increase in member acquisition.

Further, the metal reflection type hologram layer can adopt a different design for each card issuer and is difficult to copy. Therefore, even in a laminated card which is issued immediately, the hologram reflection prevention effect can be obtained. It has become possible. Furthermore, since the card base material has the oversheets on both sides, warpage is less likely to occur in the laminated card, and a predicted hologram reproduced image can be obtained.
