MEHRSCHICHTIGES ELEKTROPHOTOGRAPHISCHES AUFZEICHNUNGSMATERIAL.

摘要

Multilayer electrophotographic material has (A) an electroconductive substrate and (B) one or more layers of (b1) binder(s), (b2) charge carrier generating cpd(s). or sensitiser(s), (b3) charge carrier transport cpd(s). or photoconductor(s) and opt. (b4) additives; (b2) are new 1-cyanomethylene-4'-aminophenyl)-isoindolenine dyestuffs of formula (I). In (IA), A = CN; X, Y and Z = H and -NR1R2 = a partly unsatd. 5-6-membered heterocycle; in general: a = CN, carbo-1-4 C-alkoxy, carbamoyl, N-1-4 C-alkylcarbamoyl (in which the alkyl gp. is opt. substd. ), N-phenylcarbamoyl (in which the phenyl gp. is opt. substd. ), acetyl, benzoyl, 4-nitrophenyl or 4-cyanophenyl; X = H, Cl, 1-4C alkyl or 1-4C alkoxy and the substits. can be the same or different if n = 2; n = 1 or 2; R1 = H, Me, Et or 2-hydroxyethyl; and R2 = Ph (opt. substd. ) or cyclohexyl; or R1 = H and R2 = 1-4C alkyl; or R1 and R2 = 1-6C alkyl; 1-4C alkyl substd. by Cl, CN, OH, 1-4C alkoxy, phenoxy, 2-5C alkanoyloxy (opt. substd. ) or carbo-1-4 C-alkoxy; ally; phenyl-1-4 C-alkyl; or -NR1R2 = a satd. or partly unsatd. 5-6-membered heterocycle, Y = H; OH; Me; Et; -OCOR3; -NR4-CO-R5; -NR4-SO2-R7; N-1-4 C-alkylamino ir R1 and R2 = 1-4C alkyl; or N,N-di-1-4 C-alkylamino, N-pyrrolidinyl, N-piperidinyl or N-morpholinyl if -NR1N2 is the same as Y; R3 = linear or branched 1-12C alkyl; or Ph, opt. substd. by 1-4C alkyl or 1-4C alkoxy; R4 = H or 1-4C alkyl; R5 = H 1-12C alkyl; CF3; chloromethyl; 1-4C alkoxymethyl; phenoxymethyl (in which the PhO gp. opt. has 1 or 2 H atoms replaced ); phenylthiomethyl (in which the Ph is opt. substd.); benzyl; phenylether; 3-7C cycloalkyl; Ph, opt. substd. by 1-12C alkyl, 1-12C alkoxy or NO2; C6H5-CH=CH-; or -CH2-PO(OR6)2; R6 = 1-4C alkyl; R7 = 1-12C alkyl; or Ph, opt. substd. by 1-12C alkyl; Z = H; or if R1 ano R2 = 1-4C alkyl or allyl and Y = -NR4-COR5, Z can also = MeO or EtO.EtO.
