Abstract

Procedure for obtaining azo dyes, which in free acid form correspond to the formula **(See formula)** where D means the balance of an aromatic, carbo- or heterocyclic diazo component, R1 to R6, independent of each other, mean hydrogen, alkyl, optionally substituted, cycloalkyl, aryl or aralkyl, or, in each case R1 with R2, R3 with R4 and R5 with R6 together with the corresponding nitrogen atom can form a 5-7 membered heterocycle, Z means SO3H, OSO3H or B-SO2-NH-SO2 and B means C1-C4-alkyl or aryl, optionally substituted, Q means hydrogen, CN, CONH2, CONT1T2, SO2T1, CO2T2, COT1, NO2, halogen or SO3H, where T1 means alkyl, cycloalkyl, aryl or aralkyl and T2 means hydrogen or T1 or together with T1 and the nitrogen atom forms a 5-7 membered heterocycle and n represents the numbers 1, 2, 3 or 4, characterized in that diazotized amines of the formula D-NH2 where D has the meaning indicated above they are reacted with coupling components of the formula **(See formula)** where R1 to R6 and Q have the meanings indicated above, and the components are selected so that the dyes contain 0 to 4 groups Z, where Z means SO3H, OSO3H, B-SO2-NH-SO2, where B represents C1- C4-alkyl or aryl, optionally substituted, and, in the case that the dyes do not contain any group Z, the dyes of sulfonan or sulfatan.
