New azo dyes are disclosed which are free from sulphonic acid groups and which are optionally quaternized in the coupling component, and mixtures of such dyes, which dyes correspond to the formula ##STR1## wherein X represents chlorine, optionally substituted phenyloxy, phenylmercapto, alkylmercapto, naphthyloxy, naphthylmercapto, or a heterocyclic radical which is bound by way of --O--, --NH-- or --S--, X.sub.1 represents hydrogen, cyano, lower alkoxy, carboxy, optionally branched and/or substituted alkyl having 1 to 12 carbon atoms, optionally branched and/or substituted lower alkenyl, optionally substituted cycloalkyl, aralkyl having 7 to 10 carbon atoms, aryl, carbamoyl, or a heterocyclic radical, W represents hydrogen, a cyano group, an optionally branched and/or substituted lower alkyl group, an optionally substituted cycloalkyl group, an aralkyl group (having 7 to 10 carbon atoms), an aryl group or the radicals ##STR2## wherein R.sub.1 and R.sub.2 represent lower alkyl, R.sub.2 also represents optionally substituted cycloalkyl, aralkyl or aryl, and R.sub.3 and R.sub.4 represent hydrogen, lower alkyl, hydroxyalkyl, lower alkoxyaryl, cycloalkyl, aralkyl or aryl, and the alkyl radicals R.sub.3 and R.sub.4 can also be bound direct or by way of a hetero atom, R represents hydrogen, optionally substituted amino, optionally branched and/or substituted alkyl, optionally branched and/or substituted alkenyl, optionally substituted cycloalkyl, aralkyl or aryl or a heterocyclic radical, which dyes are useful for the dyeing and printing of synthetic fibres, especially polyester fibres if non quaternized dyes are used or acrylic fibres if quaternized dyes are used.
本发明公开了一种新的偶氮染料,其不含有磺酸基团,并且偶联组分中可以选择进行季铵化处理,这些染料的混合物符合以下公式:##STR1## 其中X代表氯,可选取取代的苯氧基,苯硫醇基,烷硫醇基,萘氧基,萘硫醇基或通过--O--,--NH--或--S--键结合的杂环基团;X.sub.1代表氢,氰基,低烷氧基,羧基,可选取1至12个碳原子的分支和/或取代烷基,可选取取代的环烷烃基,7至10个碳原子的芳基烷基,芳基,氨基甲酰基或杂环基团;W代表氢,氰基,可选取的分支和/或取代的低烷基基团,可选取取代的环烷基基团,7至10个碳原子的芳基烷基,芳基或基团##STR2## 其中R.sub.1和R.sub.2代表低烷基,R.sub.2还可以代表可选取取代的环烷基,芳基烷基或芳基,R.sub.3和R.sub.4代表氢,低烷基,羟基烷基,低烷氧基芳基,环烷基,芳基烷基或芳基,且烷基基团R.sub.3和R.sub.4也可以直接或通过杂原子连接,R代表氢,可选取取代的氨基,可选取分支和/或取代的烷基,可选取分支和/或取代的烯基,可选取取代的环烷基基团,7至10个碳原子的芳基烷基或芳基或杂环基团。如果使用未季铵化的染料,则这些染料可用于合成纤维的染色和印花,特别是聚酯纤维;如果使用季铵化的染料,则这些染料可用于丙烯酸纤维的染色和印花。
