    Abstract: 1428488 Benzoindoloquinazolone dyes BASF AG 27 July 1973 [29 July 1972] 35821/73 Heading C4P [Also in Division C2] Benzoindoloquinazolone dyes have the formula in which R is optionally substituted alkyl or optionally substituted aralkyl, X is an equivalent of an anion, n is 0 or 1; R 3 , R 4 , R 6 and R 6 are each independently H or a substituent; and A is a group of the following formulae in which R 1 and R 2 are each independently H or a substituent, R 7 and R 8 are each independently H or alkoxy, and R 9 is H, alkyl or alkoxy; provided that the molecule contains at least one acylmercapto group or a sulphur-containing ring. The dyes produce yellow, orange or red hues on textile materials based on polyester or acrylonitrile polymers, and may be used for the mass colouration of plastics such as polystyrene, polycarbonates and polyesters.

    Abstract: The invention concerns naphtholactam derivatives of formula (I), in which: R represents hydrogen, optionally substituted C1-C6 alkyl, C5-C6 cycloalkyl or substituted phenyl; R and R represent hydrogen, C1-C8 alkanoyl, optionally substituted benzoyl, optionally substituted C2-C4 alkyl, optionally substituted C2-C4 alkenyl, optionally substituted C2-C4 alkinyl, a halogen, nitro, sulphamoyl, optionally substituted hydroxy, optionally substituted mercapto, C1-C6 alkylsulphonyl or optionally substituted phenylsulphonyl; R represents hydrogen or, with R , a group of formula (II); R represents hydrogen or C1-C6 alkyl; R represents cyano, carbamoyl, C1-C4 mono- or dialkylcarbamoyl, carboxyl or C1-C4 alkoxycarbonyl; and R represents substituted C1-C4 alkyl, optionally substituted C5-C13 alkyl or benzoyl. Also disclosed is the use of these derivatives for dyeing or printing textiles.

    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.
