Abstract:
     The invention is a green light sensitive holographic photopolymer and a method of preparing holographic record dry plate, where the photopolymer is composed of film-forming polyvinyl alcohol, monomeric acylamide and diacylamide, photosensitive agent phycoerythrin B, initiator N-phenylglycine and plasticizing agent. The preparing course of the holographic dry plate: firstly dissolving the polyvinyl alcohol in the distilled water to make 7% (wt) polyvinyl alcohol water solution; secondly, adding acylamide crystals and methylene diacylamide crystals as well as N-phenylglycine and plasticizing agent to the polyvinyl alcohol water solution; thirdly, adding in phycoerythrin B dissolved in the distilled water; fourthly, pouring the above sol onto a basal plate and after the water is completely volatilized, making the photopolymer holographic drying plate. It is sensitive to the green light and the environmental humidity has a little effect on it, and it has strong shrink resistance, short drying time, diffraction efficiency able to reach 65%, and exposure strength 50 mJ/sq cm and it is especially applied to dry-processing of optical holographic record.
