However, although this method improves the concealment, it uses two kinds of magnetic materials for overprinting, and the production difficulty and production cost are relatively high
[0005] In addition, at present, the security thread that combines the first-line and second-line anti-counterfeiting features is mainly a combination of magnetic coding and non-magnetic graphics. The combination of magnetic coding and dealuminated hollow text, but the production process of the safety thread is complicated, and it needs to go through multiple processes such as film aluminum plating, dealumination, text magnetic code overprinting, compounding, etc.
With the gradual popularization and application of plastic banknotes in recent years, this type of security thread cannot meet the production requirements of plastic banknotes

The invention relates to the field of anti-counterfeiting, and discloses an anti-counterfeiting element and an anti-counterfeiting product, wherein the anti-counterfeiting element includes: a base material; and a continuous magnetic region formed of a material arranged on the base material, the magnetic The region has a plurality of first regions and second regions arranged at intervals, wherein the remanence of the first region is greater than that of the second region. The anti-counterfeiting element can well conceal the magnetic coding area, and has simple manufacturing process and low cost.
Description
technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to an anti-counterfeiting element and an anti-counterfeiting product. Background technique [0002] At present, magnetic materials are widely used in the field of anti-counterfeiting. The early magnetic security thread adopts a full-page coating method, such as patent: GB1127043, which is to evenly coat a layer of magnetic material on the entire security thread. Use the magnetic sensor to detect the magnetic material on the security line. If the magnetic signal can be detected, it is true, otherwise it is false. However, on the security thread formed by this coating method, the magnetic sensor can only detect the presence or absence of magnetism, and cannot generate a magnetic coding sequence, and this coating method is easy to be counterfeited. [0003] In order to enhance the anti-counterfeiting performance of the security thread, the patent EP0310707A2 applied by Mantegazza Co...
