    Abstract: New thiophene azo dyestuffs are of formula (I): X = COOH, CN, NO2, Cl, Br, 1-10C alkanoyl, (substd.) benzoyl, 1-4C alkylsulphonyl, (substd.) phenylsulphonyl, -COOR1 or -CON(R1)(R2); R1 and R2 independently = (substd.) 1-12C alkyl, 5-7C cycloalkyl, 3-4C alkenylor (substd.) phenyl and R2 may also = H; or R1 + R2 + N = a 5-6-membered satd. heterocycle; Y = COOH, CN, -COOR1 or -CON(R1)(R2); or Y + X = -CO-N(R2)-CO- or -CO-N(R3)-N(R4)-CO-; R3 and R4 independently = H, (substd.) 1-12C alkyl, 5-7C cycloalkyl or (substd.) phenyl; Z = COOH, 1-10C alkanoyl, (substd.) benzoyl, 1-4C alkylsulphonyl, (substd.) phenylsulphonyl, -COOR1 or -CON(R1)(R2); K = the radical of a coupling component; provided that X,Y and Z not all = CN or -COOR1. (I) can be prepd. (not claimed) by reacting diazonium salts of 2-aminothiophenes with a coupling component HK in the usual way. Some of the precursor 2-amino-thiophene derivs. are disclosed as being new (no details given).

    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: Thiazole azo-dyes of the formula … … in which… R denotes C1-C12-alkyl which is optionally interrupted by oxygen atoms, or phenyl, halogen, cyano or C1-C4-alkoxycarbonyl,… R denotes formyl, cyano, C1-C4-alkoxycarbonyl or a radical of the formula -CH=CH X , in which X and X independently of one another stand for cyano or C1-C4-alkoxycarbonyl,… R denotes C1-C12-alkyl which is optionally interrupted or substituted by oxygen atoms, C5-C7-cycloalkyl, optionally substituted phenyl, furyl, thienyl, C1-C4-alkylthienyl or pyridyl and… R and R independently of one another denote C1-C12-alkyl which is optionally interrupted and/or substituted by oxygen atoms,… with the proviso that the alkyl chain is interrupted by oxygen atoms in at least one of the radicals R , R and R , and their use for dyeing textile fibres.
