The present invention provides a hologram recording material which can modulate its refractive index effectively with visible light laser and is excellent also in transparency after this modulation. The present invention relates to a hologram recording material comprising a polymer (A) having a radically polymerizable side chain vinyl group in the molecule thereof, said polymer (A) being a polymer of monomers comprising as an essential component an acryl-vinyl monomer represented by the following formula (1): CH2=CR1C=OO-R2=CH2
wherein R1 represents a hydrogen atom or methyl group, and R2 represents a saturated or unsaturated hydrocarbon group having 1 to 20 carbon atoms, which may contain hetero atoms or halogen atoms in the molecule thereof; and a photopolymerization initiation source (B) which generates an active seed by visible light, and particularly relates to a hologram recording material having the aforementioned constitution in which the aforementioned photopolymerization initiation source (B) is a photopolymerization initiator which absorbs visible light to generate an active seed or a mixture of visible light-sensitizing dye and photopolymerization initiator.
