PHOTOSENSITIVE RECORDING MATERIAL FOR TRANSPARENT HOLOGRAM, PHOTOSENSITIVE RECORDING MEDIUM FOR TRANSPARENT HOLOGRAM AND PRODUCTION OF TRANSPARENT HOLOGRAM USING THEM

摘要

PURPOSE: To provide such a transparent hologram which can be formed by dry process and has high transparency, excellent weather resistance, high resolution, high diffraction efficiency and excellent reproducibility for reproducing wavelengths. ;CONSTITUTION: This material consists of (A) a resin which is soluble in solvent and is solid at room temp. and normal pressure, (B) polymerizable monomer which is liquid at normal temp. and normal pressure, has ≥100°C boiling point at normal pressure, and has at least one ethylenic unsatd. bond capable of radial polymn., and different in refractive index from (A), (C) photopolymn. initiator which activates radical polymn. by exposure, (D) sensitizing dye having amino groups, and (E) compd. which produces sulfonic acid deriv. by an external effect such as light and heat. The sensitizing dye remaining in the recording medium is bleached by the sulfonic acid deriv. produced from the compd. (E).;COPYRIGHT: (C)1996,JPO
