Water-soluble dyes of general formula (1) are capable of reacting with fibres and dye synthetic and natural materials containing hydroxy and/or carboxamide groups, in particular fibrous materials, such as wool and in particular cellulose fibre materials, in vivid shades. In this formula, F is the residue of a dye such as an azo dye, a heavy metal complex azo dye, anthraquinone or phthalocyanine dye; R<x> is hydrogen or low alkyl, possibly substituted by halogen, hydroxy, cyano, low alkoxy, low alkoxycarbonyl, carboxy, sulphamoyl, sulpho or sulphato; n = 1 or 2; Q is a group of formula (2a) or (2b), in which R<z> denotes hydrogen or low alkyl, possibly substituted by halogen, hydroxy, cyano, low alkoxy, carboxy, sulphamoyl, sulpho, sulphato or possibly substituted phenyl; W is possibly substituted arylene or a combined alkylene and arylene residue in which the alkylene residue and arylene residue can be substituted and the alkylene residue and alkylene-arylene residue can be interrupted by hetero groups; the -SO2-Y group is a group from the vinylsulphone series which reacts with fibres; z = 1 or 2; A = 0 or 1; B = 1 or 2, the sum of A and B being equal to 2; X together with the N atom and 1 or 2 low-alkylene groups and possibly 1 or 2 heterogroups forms the residue of a heterocyclic ring; and alk is low alkylene. |
