Abstract: A new green-sensitive photopolymer is reported, which is not sensitive to environmental humidity, and the dry time is short. The material was based on acrylamide（AA） as a monomer, N- phenyl glycine（NPG） as photoinitiator, Erythrosin B（ErB） as dye, in addition binder polyvinylalcohol and plasticizer dimethyl sulfoxide（DMSO） was added. The best concentration of NPG, ErB and DMSO is got by optimization of acrylamide-based photopolymes. Diffraction efficiency near 50% is obtained with sensitivity 60mJ/cm². The photopolymer can be used to holographic record.
