Anti-counterfeiting component and anti-counterfeiting product

Abstract

The invention discloses an anti-counterfeiting component and an anti-counterfeiting product, wherein the anti-counterfeiting component comprises a base layer. A magneto-optical information layer is arranged on the base layer, machine-readable safety information based on a magneto-optical characteristic is loaded on the magneto-optical information layer. The magneto-optical characteristic comprises a magneto-optical faraday effect or a magneto-optical Kerr effect. The anti-counterfeiting product comprises an object which is provided with the anti-counterfeiting component. The anti-counterfeiting component is adhered to the object through a first adhesive layer and / or a second adhesive layer. An embodiment of the anti-counterfeiting component and the anti-counterfeiting product can improve anti-counterfeiting performance of the anti-counterfeiting component and safety of the anti-counterfeiting product.

Description

technical field [0001] The invention relates to an anti-counterfeit technology, in particular to an anti-counterfeit element and an anti-counterfeit product. Background technique [0002] With the rapid development and popularization of color copying technology and imaging technology, counterfeiting and counterfeiting of valuable items, such as securities and brand-name products, are becoming more and more common. In order to prevent the valuable items from being counterfeited or forged, the valuable items are usually equipped with security elements, so that the authenticity of the valuable items can be verified through the security elements, so as to prevent the valuable items from being copied without authorization. [0003] At present, in the field of anti-counterfeiting technology, various security elements with anti-counterfeiting functions have been developed. For example: the security element developed by first-line anti-counterfeiting technology or public anti-count...

Problems solved by technology

[0007] However, in the process of realizing the present invention, the inventor found that when magnetic features are applied to the field of anti-counterfeiting technology, there are at least the following problems: Due to the limited information capacity, with the development of science and technology and the improvement of counterfeiting means, anti-counterfeiting based on magnetic features Information is easy to be imitated, which reduces the anti-counterfeiting performance of magnetic features, making the anti-counterfeiting security of magnetic features more and more challenging, and even fake magnetic features can be completely false; and magnetic materials with magnetic features are easy to demagnetize, which leads to its bearing The loss of information makes the public unable to recognize the authenticity of the items it marks, and brings economic losses to merchants that produce and sell real items
