AI Technical Summary

Technical Problem

Existing optical anti-counterfeiting components are difficult to manufacture, making it hard to achieve dynamic, three-dimensional effects and effectively display preset graphic and textual information.

Method used

By combining a reflective curved mirror array with a patterned microstructure, the height and period of the reflective curved mirror units are arranged according to a preset rule, and combined with a color functional layer and a reflective functional layer, an optical anti-counterfeiting element with a dynamic and three-dimensional effect is formed.

Benefits of technology

It simplifies the production process, reduces costs, improves production efficiency, and enhances the anti-counterfeiting effect through changes in brightness and color characteristics, thereby improving the anti-counterfeiting capabilities of optical anti-counterfeiting components.

Abstract

This invention provides an optical anti-counterfeiting element and an optical anti-counterfeiting product. The optical anti-counterfeiting element includes a substrate; a reflective curved mirror array disposed on the substrate, the reflective curved mirror array having multiple reflective curved mirror units; a pattern microstructure formed on the reflective curved mirror units; a reflective functional layer disposed on the reflective curved mirror array, the reflective curved mirror array sampling and synthesizing the pattern microstructure to form a first pattern feature with a dynamic and three-dimensional effect; at least a portion of the reflective curved mirror units are arranged according to a preset rule in terms of height and / or period to form a second pattern feature containing preset graphic information. This invention solves the problem of difficult manufacturing processes for existing optical anti-counterfeiting elements.
