[0002] In the prior art, the structure of the anti-counterfeiting label still has deficiencies: the anti-counterfeiting mark of the existing anti-counterfeiting label is directly exposed or a scratchable layer is arranged on the surface layer of the anti-counterfeiting label. Usually, after scratching the scratchable layer, the internally printed anti-counterfeiting mark is identified. However, the anti-counterfeiting mark inside the anti-counterfeiting label is usually an anti-counterfeiting code or has no special anti-counterfeiting effect. Whether it is the structure with the anti-counterfeiting mark exposed or the structure with a scratchable layer arranged on the surface layer of the anti-counterfeiting label, it is relatively easy to imitate and the anti-counterfeiting effect is poor.
