    • A process for colouring 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 solubilising groups, of the Formula (1) A-N=N-D, 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 -SO2F group or carries a substituent to which at least one -SO2F 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 (a) or that one of A or D does not carry an -NCH2CH(OH)CH2Cl, -NCOCH2Cl or -NCH2CH2SO2F substituent. The presence of one or more -SO2F groups in a dye molecule generally improves the properties of that dye and confers surprisingly good wet fastness and light fastness properties.
    • 合成纺织材料或其纤维混合物的着色方法,其包括向所述合成纺织品材料施用式(1)AN = ND的无水增溶基团的化​​合物或其混合物,其中:A和D各自 独立地是任选取代的杂环或碳环基团,并且A或D中的至少一个直接携带至少一个-SO 2 F基团或携带至少一个-SO 2 F基团连接的取代基,除了4-(4-氟磺酰基苯基偶氮)-N 的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,任选取代的1-苯基 - 吡唑-4-基-5-酮或(a)或A或D中的一个 不携带-NCH 2 CH(OH)CH 2 Cl,-NCOCH 2 Cl或-NCH 2 CH 2 SO 2 F取代基。 染料分子中一个或多个-SO 2 F基团的存在通常改善了该染料的性质,并赋予令人惊奇的良好的耐湿牢度和耐光性能。
