Monoazo dyes which are free from water-solubilizing groups and which contain a fluorosulphonyl group and process for colouring polyamides and polyester materials therewith

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): 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 --SO2 F group or carries a substituent to which at least one --SO2 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 --NCH2 CH(OH)CH2 Cl, --NCOCH2 Cl or --NCH2 CH2 SO2 F substituent. The presence of one or more --SO2 F groups in a dye molecule generally improves the properties of that dye and confers surprisingly good wet fastness and light fastness properties.
