OPTICAL ANTI-COUNTERFEITING ELEMENT, PRODUCT USING SAME AND PREPARATION METHOD THEREFOR

摘要

An optical anti-counterfeiting element comprises a base material (11). The base material (11) has a first surface and a second surface which are opposite to each other. The first surface is covered thereon with a micro-sampling tool (12); one part of the second surface is a micro image-text formed by a micro relief structure (13), and the other part thereof is a flat structure which does not form a micro image-text and/or a micro relief structure (14) which is different from the micro relief structure forming the micro image-text. The flat structure which does not form the micro image-text and the micro relief structure (14) different from the micro relief structure forming the micro image-text are homomorphically covered thereon with a first plating (15), the micro relief structure (13) forming the micro image-text is homomorphically covered thereon with a second plating (16), and the micro image-text is sampled by the micro sampling tool (12). Also provided is an anti-counterfeiting product using the optical anti-counterfeiting element and a preparation method therefor.

1. An optical anti-counterfeiting element comprising a base material, the base material has a first surface and a second surface which are opposite to each other; the first surface is covered thereon with a micro-sampling tool, a part of the second surface is a micro image formed by a micro relief structure, and the other part of the second surface is a flat structure which does not form a micro image and/or a micro relief structure which is different from the micro relief structure forming the micro image; the flat structure which does not form the micro image and the micro relief structure which is different from the micro relief structure forming the micro image are conformably covered thereon with a first coating, the micro relief structure forming the micro image is conformably covered thereon with a second plate, and the micro image is sampled by the micro sampling tool.
