When the ink layer 15 is arranged on the inner side of the holographic layer 12 (for example, the ink layer 11 is arranged between the plating layer 13 and the adhesive layer 14 ), the plating layer must be a transparent plating layer. The above-mentioned transparent coating is a titanium dioxide coating, a niobium pentoxide coating, a zirconium dioxide coating, a magnesium fluoride coating or a zinc sulfide coating, or is composed of other ceramic materials with a refractive index greater than 1.8.

Therefore, the present embodiment provides a card. Since the same material has the same shrinkage rate, this non-symmetrical structure enables the card to be even and flat without warping even if it is used for a long time.

Like the card provided in the previous embodiment, the card provided in this embodiment can also increase the diversity of the anti-counterfeiting effect of the card by adding an ink layer. As shown in FIG. 10 , in a preferred embodiment, the card also includes an ink layer.
