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.
