Abstract
1430242 Photo-plastic recording material MARCONI CO Ltd 18 July 1973 [10 Aug 1972] 37282/72 Heading G2C A photo-plastic recording material includes a photo-conductive layer comprising poly-N-vinylcarbazole, brilliant green and an electron acceptor, and thermoplastic material coated on the layer, the ratio of poly-N-vinylcarbazole to acceptor being between 1 and 16 moles to 1 mole. A mixture of poly-N-vinylcarbazole brilliant green and tetrachlorophthalic anhydride in an organic solvent, is coated on a glass substrate coated with tin oxide. The coated substrate is further coated with an organic solution of a thermoplastic material and dried at 70‹C. The material is used for frost imaging and recording holograms.
