A kind of invisible ultraviolet variable anti-counterfeiting label

Abstract

The invention discloses an invisible ultraviolet variable anti-counterfeit label, which comprises a fixed hole, a label plate, an anti-counterfeit device, and an anti-counterfeit mark frame. In the lower part of the label plate, an anti-counterfeiting device is provided in the anti-counterfeiting mark frame, and the anti-counterfeiting device is connected with the anti-counterfeiting mark frame. The code is copied, and the two-dimensional code graphics on both sides of the active layer are covered by the anti-counterfeiting mark frame frame to achieve the effect of hiding the two-dimensional code of the anti-counterfeiting label, preventing it from being copied and plagiarized. The graphic presentation of the two-dimensional code on both sides of the layer achieves the effect of authenticity verification, which solves the problem that the anti-counterfeit label loses protection due to oxidation of the traditional photochromic paint layer.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to an invisible ultraviolet variable anti-counterfeiting label. Background technique [0002] After the current items are sold, in order to reflect the uniqueness of the item, an anti-counterfeit label will be added to the item to prevent the item from being copied and ensure that the item is genuine; the two-dimensional code, etc. will be presented on the card board by pasting, or printing and other technologies. On, or on the packaging of a certain substance, as a unique certificate or logo of a certain substance, it is called a label. The current anti-counterfeiting labels have the following defects: [0003] Existing anti-counterfeiting labels are sensitive to ultraviolet radiation by coating the photochromic coating layer on the anti-counterfeiting label, and its color gradually changes, thereby increasing the difficulty of imitation. However, the photochromic coating layer w...

AI Technical Summary

Problems solved by technology

[0003] Existing anti-counterfeiting labels are sensitive to ultraviolet radiation by coating photochromic paint layers on the anti-counterfeiting labels, and their colors gradually change, thereby increasing the difficulty of imitation. However, the photochromic paint layers will be oxidized over time, making the anti-counterfeiting labels out of protection
