Positive-working electrophotographic photoreceptors with a protective layer comprising a melamine-formaldehyde resin, a charge-generating pigment, and a carboxylic acid and/or its anhydride. Sugimoto, Yasushi; Tachiki, Shigeo (Hitachi Chemical Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 63261268 A2 27 Oct 1988 Showa, 9 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: G03G005-14. ICS: G03G005-06. APPLICATION: JP 87-96009 17 Apr 1987. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Pos.Some commonly used reagents like 120196-33-0 is used in this experiment.-working electrophotog. photoreceptors are prepd. on a conductive layer by laminating successively a charge-transporting layer contg. an electron-donating substance, a charge-generating layer contg. a charge-generating org. pigment (I), and a protective layer, in which the protective layer is made of a hardened film comprising: (1) a butyl-etherified melamine-formaldehyde resin (II) [a no. av. mo. wt. of ￡1500] having 2-4 combined formaldehyde and 1-2 methylol group for each melamine nucleus; (2) I; and (3) an electron-accepting carboxylic acid and/or polycarboxylic acid anhydride. Thus, an Al plate was coated with a compn. contg. 2-(p-diethylaminophenyl)-4-(p-dimethylaminophenyl)-5-(o-chlorophenyl)- 1,3-oxazole and Vylon 200 (polyester resin), coated with a compn. contg. t-type metal-free phthalocyanine (III) and S-Lec BM-S (butyral resin), and finally coated with a compn. contg. II, III and pyromellitic anhydride to give a photoreceptor. The photoreceptors exhibit good electrophotog. characteristics and durability. .
