DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hologram card having a hologram formed on a card, and more particularly, to a hologram card for forming a hologram substantially in close proximity to printing.

[0002]

2. Description of the Related Art Various kinds of cards corresponding to securities such as ID cards, credit cards, prepaid cards, etc. are fraudulent, falsified, falsified, etc. due to their inherent values, and are abused. Often. Therefore, in recent years, a hologram having a hologram image that displays three-dimensional information of an object using light interference and diffraction phenomena has been used as forgery prevention means. Generally, a rainbow hologram that is a white light reproducing type is used as the hologram.

The hologram forgery prevention means forms a hologram on a desired card by using a hologram seal or a hologram transfer foil on which a hologram forming layer including a reflective layer, a picture layer, a protective layer and the like are previously laminated.

[0004] However, conventionally, a card provided with a hologram has a small size, so that the hologram is not conspicuous because it is small and is easily forged. Therefore, it is considered that it is difficult to forge. for that reason,
A hologram cannot be formed by a hologram seal or a hologram transfer foil, which has conventionally been used as a hologram forming means on a card, and it is required to form a hologram inside the card rather than forming a hologram on the card in a later process. ing.

The hologram provided on the card is:
Often combined with holograms and character information,
Character information consisting of micro-characters is formed along with the hologram design, but there were almost no problems with conventional small holograms, but various problems arise when holograms are provided on the entire surface of the card .

[0006]

In a card in which a hologram is formed on the entire surface, the hologram is provided on the card and character information is formed by printing. The step of forming will be added, the hologram is transferred, a hologram forming layer is provided, and character information is formed thereon by offset printing, but when the printing surface is exposed,
For some reason, the durability of the printed surface will be a problem, such as peeling of the printed surface and the generation of scratches.Therefore, it is necessary to further heat-press a protective layer on the printed surface, and this has the problem that the card becomes thicker. I have.

Further, the surface of the hologram forming layer to be printed may be damaged by the printing process, which is a source of defective products.

[0008] Furthermore, since the hologram and the opposite layer are formed on the entire surface of the card by enlarging the hologram, printed information such as characters and designs printed on the card surface becomes difficult to see due to the hologram effect. have.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has an object to improve the durability of a printed layer, the hologram effect by eliminating scratches on the hologram surface, and the like. Another object of the present invention is to provide a hologram card capable of reducing the thickness of the card itself by reducing the layer thickness.

[0010]

In order to achieve the above object, a hologram card according to the present invention has a single-sided or double-sided hologram card .
A hologram obtained by laminating a hologram on the entire surface of a card substrate on which a printed layer having a desired design is formed in part.
A ram card, wherein the entire hologram is transparent.
A hologram surface made of a bright or translucent substrate is formed.
Hologram forming layer and the printing on the hologram surface
Metal thin-film layers laminated except where they correspond to the layers or
A vapor deposition layer and a metal thin film layer or
And an adhesive layer bonded on the card base material.
And a portion corresponding to the printing layer of the hologram forming layer is formed as a transparent or translucent window portion.

Here, the hologram forming layer is particularly formed by forming a hologram surface on the entire surface.

The hologram-forming layer is provided with a hardly vapor-depositable ink at a position corresponding to the window.

Further, a protective layer is provided on the hologram forming layer.

Further, a picture layer is provided on the hologram forming layer.

[0015]

Therefore, in the hologram card of the present invention, a printing layer is formed on the card base material, and a metal thin film layer or a vapor deposition layer and a hologram forming layer are formed so as to be able to pass through the printing layer. The printed layer can be viewed from the outside through the window created by the above.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a plan view showing a configuration example of a hologram card according to the present invention, and FIG. 2 is a side sectional view showing a configuration example of the hologram card.

That is, as shown in FIGS. 1 and 2,
The hologram card 1 of the present embodiment is provided with a printing layer 3 on a part of a card base 2 and a transparent or translucent window D, E at a position corresponding to the printing layer 3.
Are bonded to each other.

Here, as shown in the figure, the printing layer 3 has a printing portion 3A for micro-characters and normal printing portions 3B and 3C.
It consists of

Further, the entire hologram 5 includes a transparent protective layer 6 and a predetermined image provided on the protective layer 6 (in this example,
A hologram forming layer 7 having a TOP character image), a light-reflective aluminum deposited layer 8 provided on the hologram forming layer 7, and an adhesive layer 9 provided on the aluminum deposited layer 8. .

On the other hand, in the above, for the card base material 2, for example, polyvinyl chloride, PET, paper or the like can be used.

The protective layer 6 is made of a transparent synthetic resin film (eg, polyethylene terephthalate).

Further, the hologram forming layer 7 is provided with a white light reproducing type rainbow hologram embossed surface (hologram image) on the surface of which, for example, interference fringes corresponding to the wavefront of light from the object are formed as an uneven pattern. Is what it is. As a material of the hologram forming layer 7, a transparent resin having good moldability is used. For example, vinyl chloride, a mixture of a vinyl acetate copolymer and a urethane resin, or the like can be used.

The aluminum vapor deposition layer 8 is formed by vapor deposition of aluminum on the surface of the hologram forming layer 7 to obtain a light reflective vapor deposition layer. Then, at the time of this vapor deposition, a mask having a predetermined shape is formed in a portion to be a window portion, and a non-vapor-deposited portion is created, or a non-vapor-deposited ink is applied in a predetermined shape to make vapor deposition difficult or to be vapor-deposited. Even by post-processing, the evaporated portions can be easily removed, so that the non-deposited portions are formed, so that the windows D and E are provided at the portions corresponding to the print layer 3 of the aluminum deposited layer 8. I do. The windows D and E can be arbitrarily provided at a desired size, a desired shape (a circular shape or a triangular shape in this example), and at a desired position.

Further, the adhesive layer 9 is formed by applying a transparent heat-sensitive adhesive (for example, a polyester resin and a vinyl acetate vinyl resin) on the surface of the aluminum vapor-deposited layer 8 in a thin film. The whole hologram 5 is bonded to the main body.

Next, in the hologram card of the present embodiment configured as described above, a printing layer 3 is provided on a part of the card base 2 and a transparent or translucent portion is provided at a portion corresponding to the printing layer 3. By bonding the entire hologram 5 provided with the windows D and E, the design of the print layer 3 can be changed.
It can be easily seen from outside through E.

Thus, the printing layer 3 is concealed by the hologram 5, so that the durability of the printing layer 3 can be improved.

Further, since the hologram 5 is transferred after printing, the surface of the hologram 5 is not damaged, and a sufficient hologram effect (design effect) can be obtained.

Furthermore, since no transparent sheet or the like for protecting the printing layer 3 is provided, the thickness of the hologram card 1 itself can be kept within the standard without increasing the layer thickness.

As described above, the hologram card 1 of this embodiment is provided with the printing layer 3 on a part of the card base material 2, and the transparent or translucent window portion D is provided at a portion corresponding to the printing layer 3. , E are attached to the entire hologram 5.

Accordingly, the following various effects can be obtained.

(B) Since the hologram 5 is transferred after printing, the surface of the hologram 5 is not damaged, and a sufficient hologram effect (design effect) can be obtained.

(C) Since it is not necessary to provide a transparent sheet or the like for protecting the printing layer 3 as in the prior art, the thickness of the hologram card 1 itself can be kept within the standard without increasing the layer thickness. Become.

(D) Forgery prevention technology by printing which has been conventionally used can be employed as it is.

(E) Since the size, shape, and position of the windows D and E of the hologram 5 can be freely selected arbitrarily, various designs can be accommodated.

(F) By combining the above (d) and (e), the forgery prevention effect which relied only on the hologram image is added to the design complexity and the forgery prevention effect by printing, so that the forgery is further improved. Becomes difficult.

(G) It is technically very difficult to print on a hologram a pattern requiring a high-level printing technique such as micro-characters. It is possible to print by the printing method of (1).
