Holographic recording using a multi-functional photopolymer was explored for securities and anticounterfeit. The preparation of photofunctional photopolymer film was based on monomers and photochromic fluorescent material, which provides information recording and security of the information, respectively. The content of the monomer and photochromophore for such photopolymer film was optimized to give high diffraction efficiency and high photochromic contrast. A highly secure recording and reading method was suggested for the recorded information, based on diffraction, color and fluorescence change.
