That is, the tint block using colored ink makes it difficult for a person who tries to abuse the card to replace it.
It is effective in eliminating the feeling of abuse. In addition, in the case of a copy-forgery-inhibited pattern using transparent fluorescent ink, if a trace of misuse is seen after cutting the card, it is necessary to use a fluorescent light verification device such as a black lamp to determine whether it was actually misused. Since it is a transparent ink that is used, it does not interfere with the precious metal and jewel parts inside it, and it will not be noticed by those who try to abuse it.

Furthermore, by only printing colored ink and transparent fluorescent ink on the front and back, there is no special increase in cost, and it is also technically possible to print these inks on the transparent oversheet. Further, it can be easily performed by screen printing, offset printing, or the like.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2 are views showing an example of the structure of a card according to the present invention. FIG. 1 is a plan view of the front side of the card, and FIG.
3 is a cross-sectional view taken along the line XX ′ in the figure.

1 and 2, in the card of the present embodiment, a noble metal (for example, pure gold) 0 is exposed inside the card base 1 and a part thereof is exposed on the front and back surfaces of the card base 1. Provided on the front and back surfaces of the card base 1,
The transparent oversheets 21 and 22 are provided by adhering a plurality of layers (three layers in this example) with an adhesive or the like, and further a three-layer oversheet provided on the front surface and the back surface of the card base 1.
Of 21,22, the inner oversheet (in this example,
A tint block is printed by, for example, screen printing, offset printing or the like with the colored ink 3 and the transparent fluorescent ink 4 on a portion corresponding to the noble metal 0 in each of the second and same oversheets). In this case, it is preferable that the tint block printed with the colored ink 3 and the transparent fluorescent ink 4 is as simple as possible so as not to impair the effect of the precious metal 0.

It should be noted that the colored ink 3 has a slightly noble metal or jewel 0 inserted therein so that the noble metal or jewel 0 can be seen from the surface of the card through the oversheets 21 and 22.
By forming the tint block so as to cover the periphery thereof, it is possible to make it difficult to remove the precious metal or the jewel 0 from the card and to prevent the decorative effect from being reduced.

Here, the card base 1 is made of a plastic sheet such as polyvinyl chloride or polyethylene.
