Description

[Detailed Description of the Invention] The present invention relates to a card for identification, etc., which is provided with anti-counterfeiting measures.

Recently, opportunities to use cards such as identification cards, credit cards, cash cards, etc. have increased, and as a result, accidents, fraud, and counterfeiting related to cards have increased, and everyone involved has been worried. The present invention was devised in light of this point, and by providing an aluminum layer with a mirror function, hidden letters reflected on the aluminum layer can be seen or hidden depending on the viewing angle, and a new pattern can be created. This feature prevents forgery and unauthorized use.

The present invention will be explained in detail according to the drawings.

FIG. 1 of the drawings is a sectional view showing the configuration of the present invention. First, lower printing layers 4a to 4c are provided at predetermined positions on the upper surface of a transparent center core 1 made of a vinyl chloride sheet or the like. Next, opaque film print layers 3a to 3c are provided on these lower print layers to form a lower print layer 4a.
~ Completely hides 4c.

Furthermore, upper printed layers 2a to 2d are provided thereon, and there are also those such as 2a to 2c in which the upper printing layers are provided on the opaque film printing layer, and the upper printing layers 2d in which the upper printing layers are provided directly on the transparent center core. Finally, a transparent overcoat layer made of a vinyl chloride sheet or the like is provided on top of this to protect the surface.

An aluminum layer 6 is provided on the lower surface of the transparent center core by a method such as aluminum foil adhesion or aluminum vapor deposition, and if necessary, printed layers 7a to 7e are provided thereon, and a transparent overcoat layer 8 is further provided thereon. establish.

Although the configuration is as described above, the actual method of use will be explained below. First, when the viewer looks from the position I, only the upper printed layer 2b is visible. When viewed from the next position, the viewer can see the image 4b' reflected on the lower printing layer 4b or the aluminum layer. When viewed from the next position, if the upper printing layer 2d is a solid printing layer, the image 4b' will be hidden by the upper printing layer and will not be visible. Also, if this upper printing layer is formed in a certain pattern, and the lower printing layer is configured so that it combines with the image reflected on the aluminum layer to form a new pattern,
It becomes more difficult to counterfeit and increases security. In this example, the upper printing layer, the opaque coating printing layer, and the lower printing layer are provided on the transparent center core, but these may be provided on the transparent oversheet side and attached to the transparent center core.

Similarly, instead of providing the printed layer 7 on the aluminum layer 6, the printed layer 7 may be provided on the transparent oversheet 8 and adhered to the aluminum layer. The transparent center core 5 and the transparent oversheets 1 and 8 are made of synthetic resin such as vinyl chloride, and the most suitable thickness of the transparent center core is about 1 to 2 mm, and the thickness of the transparent oversheet is about 0.1 mm.

As mentioned above, the present invention is extremely difficult to counterfeit because the aluminum layer acts as a mirror and allows the hidden characters and patterns inside the card to be confirmed by viewing them from a certain angle. It can also be used for greeting cards, etc.

〔Example〕

After printing a hidden pattern on the upper surface of a 1mm thick transparent center core made of PVC, an opaque film printing layer is formed to hide it, and then combined with the user's name, age, address, etc. and the hidden pattern. A 0.1 mm thick transparent PVC oversheet is pasted on top of the pattern. An identification card was formed by pasting 0.1 mm thick aluminum foil on the lower surface of the transparent center core and pasting a 0.1 mm thick PVC transparent oversheet with information printed on the back.
