3D Image Recording on Photopolymer Films Containing Molecular Composites of a New s-Triazine Monomer and Acrylate Monomer by Dual Photopolymerization
Abstract:Three dimensional (3D) image recording on photopolymer film was explored using a mixture of s-triazine diepoxy (SEP) and ethylene glycol phenyl ether acrylate (PA) as a monomer to induce cationic and radical polymerization during the holographic recording. The photopolymer films were sensitive to a visible light source and polymerized upon excitation with a visible laser. 3D image was recorded on the photopolymer film by holographic recording using a 491 nm laser. The film containing a molecular composite of SEP and PA showed high diffraction efficiency via dual photo polymerization. Within 10 min of recording the image formation was vivid. In this way 3D screw and a letter image with large viewing angle were obtained onto the photopolymer film. The images were stable for longer than 3 month at RT and 5 hr at 85 °C, when read by a visible light.
