Abstract: 
New holographic recording material based on photopolymerizable systems have contributed significantly to recent growth of holographic applications. Previously, we report that on photopolymerizable system with the presence of the difunctional monomer, ethylene glycol dimethacrylate improves the behavior of the system and particularly to elucidate the role played by eosin ester with oxooxime group in the production of amine initiator radicals. This comparative study has been carried out in our laboratory using differential scanning photocalorimetry and holography. The results of the new photosensitive recording material for holography indicate that this system can be used for the formation of very promising photopolymer with better performance. The aim of this work has been changed the crosslinking monomer to decrease the energetin sensitivity and know the rest of the behavior. The new photopolymerizable mixture containing pentaethritol triacrylate in the same relation with the ethylene glycol dimethacrylate mixture. A diffraction efficiency of 80% is achieved with a energetic sensitivity of 3 J/cm2 at 514 nm, and the spatial resolution is up to 2000 l/mm.
