Abstract
Information characteristics of holographic recording media based on poly(N-epoxypropylcarbazole) films containing charge-transfer systems as photogeneration sites were studied, in which donor and acceptor molecules (or their fragments) either formed adducts between one another or were covalently bound by polymethylene spacer groups or by a system of conjugated π bonds. The recording media based on compounds with intramolecular charge transfer over a system of conjugated bonds for recording holograms using the photothermoplastic method exhibit an narrower intense spectral sensitivity band and a high holographic sensitivity. In these media, the effect of prolonged storage of latent image before the development of a hologram was revealed and explained.
