HOLOGRAM RECORDING MATERIAL AND PRODUCTION OF VOLUMETRIC PHASE TYPE HOLOGRAM FORMED BY USING THE SAME

摘要

PURPOSE: To provide the hologram recording material exhibiting an excellent sensitivity and the volume phase type hologram formed by using the material. ;CONSTITUTION: This hologram material consists of a combination of a high- polymer compd. (A) which is a single polymer of a vinyl monomer or a copolymer of ≥2 components of vinyl monomers, a compd. (B) having at least ≥1 pieces of polymerizable ethylenic unsatd. bonds, a ketocumarine deriv. (C) and sulfonium org. boron complex (D). This process for production of the volumetric phase type hologram consists in subjecting the hologram recording material to hologram exposing, then adding light and (or) heat thereto. As a result, the volumetric phase type hologram which has the high sensitivity, is chemically stable and has a high resolution, high diffraction efficiency and high transparency is easily produced.;COPYRIGHT: (C)1994,JPO&Japio
