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.
一种用于染色合成纺织材料或其纤维混合物的方法,包括将公式(1)中不含水溶性基团的化合物或混合物施加于合成纺织材料上:A-N.dbd.N-D 公式(1),其中A和D各自独立地是可选取代的杂环或碳环基团,且A或D中至少一个直接带有至少一个-SO.sub.2 F基团或带有可附加至少一个-SO.sub.2 F基团的取代基,但4-(4-氟磺酰基苯偶氮)-N,N-二甲基苯胺除外。其中至少一个A或D不是3,5-二氟磺酰基噻吩-2-基,可选取代的1-苯基吡唑-4-基-5-酮或##STR1##,或者其中至少一个A或D不带有-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,并赋予惊人的湿度快速性和耐光性。
