▎ 摘　　要

NOVELTY - Anti-counterfeiting film comprises a substrate, a graphene pattern disposed on at least a portion of one surface of the substrate and a metal film for covering the graphene pattern, disposed on at least a portion of one surface of the substrate. The metal film has a thickness less than the minimum thickness at which the inherent infrared radiation is measured. USE - Used as anti-counterfeiting film. ADVANTAGE - The anti-counterfeiting film has excellent anti-counterfeiting efficacy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for adjusting infrared radiation, comprising forming a graphene pattern on at least a portion of one surface of the substrate, and forming a metal film for covering the graphene pattern on the substrate.
