Electrophotographic photoreceptor containing anthanthrone derivative charge-generating agent

Electrophotographic photoreceptor containing anthanthrone derivative charge-generating agent. Nakamura, Chisako; Nabeta, Osamu (Fuji Electric Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 03238465 A2 24 Oct 1991 Heisei, 6 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: G03G005-06. 4378-61-4 which is the cas registry number is also used here. APPLICATION: JP 90-35311 16 Feb 1990. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The photoreceptor has an org. charge-generating layer contg. ￡200-ppm-Ca-contg. anthanthrone deriv. I (X = halo, NO2, cyano, CO2H; n = 0-4) and a charge-transporting layer on an elec. conductive substrate. The photoreceptor showed improved red color reproducibility and high photosensitivity. .

Composite electrophotographic plates

Composite electrophotographic plates. (Konishiroku Photo Industry Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58001155 A2 6 Jan 1983 Showa, 11 pp. (Japanese). 4378-61-4 and 1159-53-1 are cas registry numbers. These chemicals are also mentioned in this article. (Japan). CODEN: JKXXAF. CLASS: IC: G03G005-06; G03G005-07. APPLICATION: JP 81-99880 26 Jun 1981. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Charge carrier-transfer layers of composite electrophotog. plates contain a tert-amine of the formula RNR1R2 (R,R1,R3 = arom. or heterocyclic moiety) and an org. semiconductor polymer having condensed arom. or heterocyclic rings on side chains. The composite electrophotog. plates may also contain an electron acceptor type compd. in the charge carrier-transfer and/or charge carrier-generating layers. The composite electrophotog. plates exhibit improved durability. Thus, an Al-laminated polyester film support was coated with maleic anhydride-vinyl acetate-vinyl chloride copolymer, then coated with 4,10-dibromoanthanthrone (by vacuum deposition), and coated with a compn. contg. poly(N-vinylcarbazole), 4,4'-dimethyltriphenylamine, and Panlite L-1250 (a polycarbonate) resin to give a composite electrophotog. plate which showed excellent durability and sensitivity. .
