By employing new types of multi-color photosensitizers and photochemical promoters to conventional photocrosslinking gelatin system, a high-quality single-layer panchromatic chromate gelatin material is successfully achieved. Its characteristics such as spectral response, photosensitivity of three primary colors, spectral selectivity of volume reflection hologram,angular and wavelength selectivity of volume transmissioin hologram, are studied in detail. Some preliminary experimental results in true-color reflection holography,angle and wavelength multiplexing holographic storage are also reported in this paper.
