Abstract: New holographic recording materials based on photopolymerizable systems have contributed significantly to the recent growth in the number of holographic applications. In this paper we present the study of a dry film photopolymerizable recording material based on PVA-acrylamides. The photopolymerizable system used consisted of acrylamide as monomer, triethanolamine es radical generator and eosin yellowish as sensitizer. All the components were supported on a film of polyninylalcohol. We estudied the behavior of this photopolymerizable when holographic gratings with a spatial frequency of 1000 lines/mm were stored. The diffraction efficiency and sensitivity were studied for different values of intensity. Diffraction efficiencies of 70% with energetic sensitivities of 200 mJ/cm^2 were obtained using a recording intensity of 7 mW/cm^2.
