Abstract New holographic recording materials based on photopolymerizable systems have contributed significantly to the recent growth of holographic applications. Previously, we reported that in photopolymerizable systems with a difunctional monomer, Ethylene Glycol DiMethAcrylate (EGDMA) improves the behaviour of the system and explains the role played by an eosin ester that has an oxo-oxime group in the production of amine initiator radicals. This comparative study was carried out in our laboratory using differential scanning photo-calorimetry and holography. The results of the new photosensitive recording materials for holography indicate that this system can be used for the formulation of very promising photopolymers that have a better performance. The aim of this study was to change the crosslinking monomer in order to increase the energetic sensitivity and discover the rest of the behavior. The new photo-polymerizable mixture contains PentaErythritol TriAcrylate (PETA) in a 1:1 ratio of volume and a 2-Hydroxy-Ethylene MethAcrylate monomer (HEMA). A diffraction efficiency of 80% is achieved with an energetic sensitivity of 3 J/cm2 at 514 nm, and the spatial resolution is up to 2000 lines/mm.
