    Abstract: Dyestuff mixtures containing 50 to 95% by weight of a 4-chloro-2-nitrophenylazohydroxypyridone dyestuff and also 5 to 50% by weight of a brominated quinophthalone dyestuff and/or 5 to 50% by weight of a chlorinated quinophthalone dyestuff and/or 5 to 20% by weight of an unsubstituted quinophthalone dyestuff; dyestuff preparations containing the new dyestuff mixtures; and the use of dyestuff mixtures for dyeing or printing by the direct printing process on polyester.

    Abstract: Thiophene azo dyes I … … where the substituents have the following meanings:… R = cyano or C1-C4-alkoxycarbonyl; R = halogen; C1-C6 alkyl whose carbon chain may be interrupted by one or two oxygen atoms in ether function; C1-C6-alkoxy or C1-C6-alkylthio which may each carry phenyl as substituent; phenylthio or phenylsulphonyl which may each carry halogen, C1-C4-alkyl or C1-C4-alkoxy as substituents; R = cyano; C1-C4-alkanoyl, benzoyl, C1-C4-alkylsulphonyl or phenylsulphonyl; R = hydrogen; cyano; C1-C4-alkoxy which may carry hydroxyl or C1-C4-alkoxy as substituents; C1-C4-alkoxycarbonyl, aminocarbonyl, mono- or di- C1-C4-alkylaminocarbonyl; R = hydrogen; C1-C4-alkyl or C1-C4-alkoxy which may each carry hydroxyl, C1-C4-alkoxy or C1-C4-alkanoyloxy as substituents; C1-C4-alkanoyloxy which may carry hydroxyl, chlorine, cyano, C1-C4-alkoxy or phenoxy as substituents; C1-C6-alkanoylamino which may carry hydroxyl, chlorine, cyano, C1-C4-alkoxy, phenoxy or C1-C4-alkanoyloxy as substituents; benzoylamino which may carry chlorine, cyano, nitro, C1-C4-alkyl, C1-C4-alkoxy, C1-C4-alkoxycarbonyl or C1-C4-alkylsulphonyl as substituents; C1-C4-alkoxycarbonylamino or di-C1-C4-alkylaminocarbonyloxy whose alkyl groups may be bonded together to form a 6- or 7-membered ring containing the nitrogen atom of the amino group; R = hydrogen; C1-C10-alkyl whose carbon chain may be interrupted by one to three oxygen atoms in ether function and which may carry hydroxyl, halogen, cyano, C1-C4-alkanoyloxy or C1-C4-alkoxycarbonyl as substituents; C3-C5-alkenyl which may carry hydroxyl, halogen, C1-C4-alkoxy or C1-C4-alkanoyloxy as substituents; R = hydrogen; halogen; cyano; one of the alkyl groups R of the type defined; C1-C4-alkoxy; amino or mono- or di-C1-C4-alkylamino; R = one of the radicals R . … The thiophene azo dyes I are chiefly used as disperse dyes for dyeing textile material, in particular polyesters.

    Abstract: 1. A vat dye based on a condensed reaction product of monobromofluoranthene which contains not more than 7% of dibromofluoranthene with 1-amino-4-benzoylaminoanthraquinone, obtainable by carrying out the condensation of the reaction product to give the carbazole compound at from 50 to 70 degrees C in 83-88% strength sulfuric acid and, after the conversion to the carbazole compound, effecting further bromination to a bromine content of from 20 to 23% by weight.
