Abstract: PROBLEM TO BE SOLVED: To provide a hologram recording material which allows the formation of a volume phase type hologram which is excellent in weather resistance, heat resistance, chemical stability and further preservable stability and is excellent in high resolution by a dry process, high diffraction efficiency, high transparency and reproduction wavelength reproducibility.
