A new acrylamide-based photopolymer sensitive to green light is reported in this paper. This material is composed of monomer, crosslinker, photoinitiator, coinitiator, and polymeric film-forming binder. Holographic diffraction efficiency as high as 50% can be attained. The best dye concentration is got by optimization of material's composition. A hologram can be stored in this photopolymer and the image can be reconstructed clearly. So this photopolymer is promising to high-density holographic recording.
