PCT No. PCT/GB94/02831 Sec. 371 Date Jul. 15, 1996 Sec. 102(e) Date Jul. 15, 1996 PCT Filed Dec. 30, 1994 PCT Pub. No. WO95/20014 PCT Pub. Date Jul. 27, 1995A 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=N-DFormula (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 -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 <IMAGE> 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. |
