The optical storage anti-fake element at least comprises a pattern layer, the pattern layer is provided with azo polymers, the azo polymers at least comprises one kind of azobenzene chromophore, the upper surface of the pattern layer is provided with a continuous or discontinuous concave-convex structure, and optical information which is erasable, capable of being read, written and changed, and capable of being read and identified by machines is written in the concave-convex structure. The optical storage anti-fake element has high anti-fake reliability.

Description

technical field [0001] The invention relates to an optical storage anti-counterfeiting element, a manufacturing method of the optical storage anti-counterfeiting element, an application of the optical storage anti-counterfeiting element and an optical element for writing optical information during the manufacturing process of the optical storage anti-counterfeiting element, belonging to the field of optical anti-counterfeiting. Background technique [0002] In the markets of daily necessities, clothing, music software, supplies, ID cards, banknotes, and securities, there are often high-quality products that are manufactured to imitate furniture in appearance, and this has become a problem that cannot be ignored. In this situation, in order to maintain security and brand value, it is necessary to have a technology that can identify the authenticity of items, thus, anti-counterfeiting technology (anti-counterfeiting components) came into being. [0003] Several anti-counterfei...
