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 oversheet is laminated, the card substrate is colored, and the oversheet has a transparent or semitransparent hologram layer (11) formed on a part or the entire surface. It is characterized by being.

[0007]

According to the present invention, the card substrate is colored, and the transparent or semi-transparent 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 can be improved. In addition to having novelty and a sense of luxury, it is difficult to copy the transparent hologram layer, so that an anti-counterfeiting 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.

In this embodiment, a core material such as colored synthetic resin such as PET and vinyl chloride is used for the back side of the card substrate 20. The card equipment 20 is composed of a normal white card core material and a colored card core material. Since one of the core materials is printed with characters and pictures, it is preferably white. When the card base material 20 is colored, the transparent or semitransparent hologram forming layer 11 is formed.
Is easier to see. For easy viewing, dark colors are good,
Examples include black, blue, brown and green. The reason for using the colored core material is that if the core material is subjected to solid printing by offset printing or the like, the adhesiveness of the oversheets 10, 30 and the like is poor. Further, when the colored core material is used, the printing layer 43 is partially formed on the core material.
There is an advantage that it is possible to form. Print layer 43
Are more effective when tuned with the hologram forming layer 11.

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 backside of the hologram forming layer 11. It consists of 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. 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 an effect 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.

When the effect layer 13 is used as a transparent hologram, it is necessary to have reflective transparency, and the effect layer 13 is different from the hologram resin layer 12 in a transparent material having a different refractive index or a metal thin film having a thickness of less than 200Å. Layers and the like. In the former case, the refractive index of the effect layer 13 may be larger or smaller than the refractive index of the hologram resin layer 12, but the difference in refractive index is preferably 0.1 or more, and the difference is 0. 0.5 or more, more preferably 1.0 or more. Also, in the latter case, although it is a metal thin film, since the thickness is less than 200Å, the light wave transmittance is large,
Therefore, in addition to the hologram effect expressing action, the lower layer non-concealing action is exhibited.

The material of the effect layer 13 is, for example, Sb _{2 which} is a transparent continuous thin film having a refractive index larger than that of the resin layer 12.
Examples include S ₃ (3.0) and ZnS (2.1). To form the effect layer 13 on the hologram resin layer 12, a thin film forming method such as a vacuum vapor deposition method or a sputtering method may be used. Details of the material and manufacturing method of the hologram forming layer 11 are disclosed in US Pat. No. 4,856,857 of the present applicant. The effect layer 13 is 200
A metal thin film having a thickness of Å or more may be used, and in that case, the hologram forming layer 11 exhibits a silver color.

The surface protective film 14 is for protecting the hologram forming layer 11 from damage due to an external force and for imparting strength, and is not necessary for the transfer foil. As a material of the surface protection film 14, a cellulosic resin, a polyimide resin, a polystyrene resin, a polyester resin, a polyolefin resin, a simple substance, a mixture, a copolymer, or the like can be used. The surface protective film 14 preferably has a thickness of about 5 to 200 μm.
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 forming layer 11 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 resins, epoxy resins, rubber resins, and ionomer resins can be used. The adhesive layer 15 has a thickness of 0.1 to
It may be about 50 μm, but is preferably 1 to 10 μm.

In addition, on the entire surface of the oversheet 10 on the back side,
Although the example in which the transparent hologram layer is provided has been described, it may be formed on a part of the back surface, or may be formed on the entire surface or a part of the front side oversheet 30.

[0018]

As described in detail above, according to the present invention, since the card substrate is colored and the transparent hologram layer is formed on a part or the entire surface of the oversheet, the background color can be selected. The degree of freedom is high, the three-dimensional effect is very well expressed, and the novelty and luxury of the design can be obtained. Therefore, the card issuer can contribute to an increase in member acquisition.

Further, the transparent hologram layer can have a different design for each card issuer and is difficult to copy. Therefore, even in a laminate card which is immediately issued, the hologram forgery effect can be obtained. Became 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.
