HYBRID ANTI-COUNTERFEIT FILM, METHOD OF THE SAME, HYBRID ANTI-COUNTERFEIT METHOD, AND HYBRID ANTI-COUNTERFEIT SET

摘要

PURPOSE: A complex counterfeit preventing film, a method for manufacturing the same, a complex counterfeit preventing method, and a complex counterfeit preventing set are provided to effectively prevent the generation of counterfeit products. CONSTITUTION: A display region includes a magnetic solution. The magnetic solution is dispersed in a hardening medium. The magnetic solution is colloidal solution in which a plurality of magnetic particles charged with identical electric charges is dispersed in fluid. If magnetic field is applied to the magnetic solution, the reflected light or the transmittance of the magnetic solution is changed. If specific energy is applied to the hardening medium, a material in the hardening medium expresses a specific property.
