STRUCTURE FOR PREVENTING COUNTERFEIT, FALSIFICATION OR REUSE, AND METHOD FOR DISCRIMINATING COUNTERFEIT, FALSIFICATION OR REUSE USING THE SAME

摘要

Disclosed is a structure for preventing counterfeit, falsification or reuse, including a metal layer, a photoconversion pattern layer including a plurality of photoconverting nanoparticles formed on the metal layer, a metal pattern layer placed on the metal layer and the photoconversion pattern layer, and an adhesive film placed on the metal pattern layer. Accordingly, the structure for preventing counterfeit, falsification or reuse according to the present disclosure allows a pattern indicating a genuine product to be easily identified with an eye through infrared light irradiation, and is fundamentally impossible to re-assemble after deformation of the structure caused by disassembly of a packaging container, thereby preventing counterfeit, falsification or reuse.
