Acid azo dyes containing thiazole coupling components, of the general formula STR1 where D is the radical of a diazo component, R is hydrogen, acetyl, benzoyl or an aliphatic, cycloaliphatic, aromatic or heterocyclic radical, R1 and R2 independently of one another are optionally substituted alkyl, cycloalkyl, aralkyl or aryl, R1 may also be hydrogen and R1 and R2 together with the nitrogen may be a heterocyclic radical, and the radicals D, R, R1 and/or R2 may in total contain from 1 to 4 --SO3 H groups. The deeply colored novel compounds are particularly suitable for dyeing polyamides, and the dyeings obtained have very good lightfastness and wetfastness.
