Abstract：Photosensitive films for holography were fabricated through homogeneous mixing of poly（vinylacetate）， 2-（2- biphenylyloxy）ethylacrylate，anepoxidecompound，andaphotoinitiator indichloromethane，followedbybladecoatingand drying.Photopolymerized holographic plasticswere thenprepared using the principleofholographic photopolymerizationinduced phaseseparationundercoherentlaseriradiation.Theinfluencesofthreeepoxides，namely2-biphenyl glycidylethr （BGE），ethylene glycol diglycidylether （GDE），and glycidyl phenyl ether（GPE），on the performance of photopolymerized holographicplasticsweresystematicallinvestigatedusing ultraviolet-visible spectroscopy（UV-Vis），Fourier-transform infraredspectrosopy（FT），anddiferetialsaingcalorimetry（DSC）spectivelyResultsiicatethattetio eficiency of holographic plastics canbesignificantly enhanced withanaugmentationofthe epoxide content.However，this would be decreased when the epoxide content is too high. When the mass fraction of BGE reaches 24% ，monochromatic holographic plasticsin blue，greenandredcolors canbeachievedrespectively.These plastics exhibit excelent difraction efficiencies of over 97% ，highvisible light transmittance of above 80% ，and lowhaze of under 3% .Afull-colorholographic plastic was also fabricated， exhibiting diffraction eficiencies of 65% ， 56% and 46% for blue，green and red colors， respectively， with visible light transmittance higher than 70% and with a haze of 2%
