HOLOGRAPHIC RECORDING MATERIAL AND PROCESS FOR PRODUCING HOLOGRAMS

摘要

A holographic recording material comprising a polymer containing vinylcarbazole rings, a cyclic cis- alpha -dicarbonyl compound capable of forming a radical by light irradiation and a dye as a photosensitizer or a spectral sensitizer. A hologram can be obtained by exposing the holographic recording material to an interference pattern of a radiation to form a holographic interference pattern, subjecting the material to a swelling treatment in a first medium, and then subjecting the material to a contraction treatment in a second medium.
