HOLOGRAPHIC RECORDING MATERIAL, VOLUME HOLOGRAPHIC MEDIUM, AND METHOD FOR PRODUCING VOLUME HOLOGRAPHIC MEDIUM

摘要

The present invention addresses the problem of providing: a holographic recording material for volume holographic media, which has excellent diffraction efficiency, light transmittance and durability; a volume holographic medium; and the like. The above-described problem is solved by a holographic recording material which contains a metallopolymer precursor and a photopolymerizable compound. The above-described problem is also solved by a volume holographic medium 10 which contains a metallopolymer having a structure represented by general formula (2) in a volume holographic recording layer 11.Sb-(R-Sb'-M-Sb')_n-R-Sb General formula (2)(In general formula (2), M represents a predetermined metal element; R represents a divalent linking group; n represents an integer of 1 or more; each of Sb-R-Sb' and Sb'-R-Sb' represents a Schiff base ligand; and Sb' represents a chemical structure that has the same skeleton as Sb and has been converted into a state where Sb is coordinately and/or covalently bonded to the metal element M.)
