A process for coloring a synthetic textile material or fibre blend thereof which comprises applying to the synthetic textile material a compound or mixture thereof, which is free from water solubilizing groups, of Formula (1): A--N.dbd.N--D Formula (1) wherein A and D each independently is an optionally substituted heterocyclic or carbocyclic group and at least one of A or D carries directly at least one --SO.sub.2 F group or carries a substituent to which at least one --SO.sub.2 F group is attached except for 4-(4-fluorosulphonylphenylazo)-N,N-dimethylaniline, provided that one of A or D is not 3,5-difluorosulphonylthien-2-yl, optionally substituted 1-phenyl-pyrazol-4-yl-5-one or ##STR1## or that one of A or D does not carry an --NCH.sub.2 CH(OH)CH.sub.2 Cl, --NCOCH.sub.2 Cl or --NCH.sub.2 CH.sub.2 SO.sub.2 F substituent. The presence of one or more --SO.sub.2 F groups in a dye molecule generally improves the properties of that dye and confers surprisingly good wet fastness and light fastness properties.
一种用于给合成纺织材料或其纤维混合物着色的方法,包括向合成纺织材料施加一个不含水溶解基团的化合物或其混合物,其化学式为(1):A--N.dbd.N--D 化学式(1)其中A和D各自独立地是一个可选择地取代的杂环或碳环基团,且A或D中至少一个直接携带至少一个--SO.sub.2 F基团,或携带一个取代基,至少一个--SO.sub.2 F基团附着在该取代基上,但不包括4-(4-氟磺酰基苯基偶氮)-N,N-二甲基苯胺,条件是A或D中的一个不是3,5-二氟磺酰基噻吩-2-基,可选择地取代的1-苯基吡唑-4-基-5-酮或##STR1##,或者A或D中的一个不携带--NCH.sub.2 CH(OH)CH.sub.2 Cl,--NCOCH.sub.2 Cl或--NCH.sub.2 CH.sub.2 SO.sub.2 F取代基。染料分子中存在一个或多个--SO.sub.2 F基团通常会改善该染料的性能,并赋予出乎意料的良好湿度牢度和光牢度性能。
