Abstract

A new photopolymer composite containing triazine monomer and photochromophore was explored as a holographic recording media that show color change after holographic recording. Photopolymer films prepared by mixing s-triazine (ST) methacrylic monomer, photochromic dye, aromatic acrylic monomer, binder polymer, and photo initiator were sensitive to a visible light and polymerized upon excitation with a visible laser light. The real-time diffraction efficiency was determined and correlated to the polymerization of the film. The diffraction efficiency in the presence of photochromophores was similar to that without them. After holographic recording to generate 3D image, an external light source was introduced to change the color of the recorded area. The color change from the 3D image was visible and reversible.
