HOLOGRAM PHOTOSENSITIVE RECORDING MATERIAL AND HOLOGRAM PHOTOSENSITIVE RECORDING MEDIUM, AND HOLOGRAM MANUFACTURE USING THEM

摘要

PURPOSE: To improve the chemical stability, the resolution, the diffraction efficiency, the transparence, and the regeneration wavelength reproducibility, by mixing a specific thermosetting bisphenol A type epoxyoligomer and a specific thermosetting epoxyoligomer. ;CONSTITUTION: An aliphatic monomer which can be radical polymerized is distributed evenly in the solid phases which consists of a thermosetting bisphenol A type epoxyoligomer shown in the formula (where n=1 to 20), which can be solvent solved and cation polymerized, has the epoxy equivalent 800 or more, and has the melting point 50° or higher; and a thermosetting epoxyoligomer which can be solvent solved, and cation polymerized, and has the epoxy equivalent less than 1000, and a high refraction factor. When a laser interference ray is radiated on this recording material, a photoinitiator generates simultaneously a radical seed, and a Brϕnsted acid or a Lewis acid to activate the radical polymerization and the cationic polymerization by the function of a sensitizer, at the position of a strong optical interference function, of the positions of the laser radiation.;COPYRIGHT: (C)1996,JPO
