title: Photopolymer system and its application to a color hologram.
abstract: We present a new type of photopolymer system for recording reflection holograms. The photopolymer system with radical and cationic photopolymerization controlled by the wavelength of light gives us enhanced diffraction efficiencies and a balanced recording sensitivity (20-60 mJ/cm(2)) in the blue to red region of the spectrum. In color hologram recordings, diffraction efficiencies of ˜ 60% are obtained when a photopolymer film is used that is composed of different spectrally sensitive photopolymer layers.
