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, R.sup.1 and R.sup.2 independently of one another are optionally substituted alkyl, cycloalkyl, aralkyl or aryl, R.sup.1 may also be hydrogen and R.sup.1 and R.sup.2 together with the nitrogen may be a heterocyclic radical, and the radicals D, R, R.sup.1 and/or R.sup.2 may in total contain from 1 to 4 --SO.sub.3 H groups. The deeply colored novel compounds are particularly suitable for dyeing polyamides, and the dyeings obtained have very good lightfastness and wetfastness.
含有噻唑偶联组分的酸性偶氮染料,其一般式为##STR1##其中D是重氮组分的基团,R是氢、乙酰、苯甲酰或脂肪、环脂肪、芳香或杂环基团,R.sup.1和R.sup.2彼此独立地可以是选择性取代的烷基、环烷基、芳基或芳基烷基,R.sup.1也可以是氢,R.sup.1和R.sup.2与氮一起也可以是杂环基团,基团D、R、R.sup.1和/或R.sup.2总共可能含有1至4个--SO.sub.3 H基团。这些深色新型化合物特别适用于染色聚酰胺,所得染色具有非常良好的耐光性和耐湿性。
