New fibre-reactive vinyl- or 2-substd.-ethyl-sulphonyl naphthalene-1-sulphonic acid (2-azo-3) 1-naphthol mono- or di-sulphonic acid dyestuffs are of formula (I) where m = 0 or 1; n = 0 or 1; and m+n = 1 or 2; p = 0 or 1; q = 0 or 1; X = vinyl or -CH2CH2-Y; Y is a gp. eliminated under alkaline conditions; W = a pyrimidin-4-yl or 2-amino-4-fluoro-s-triazin-6-yl gp. of formulae (II) and (III). A = H, Cl, Br, CN or 1-4C alkylsulphonyl; Z1 and Z2 independently = H, Cl, Br, F or 1-4C alkylsulphonyl but not both = H or 1-4C alkylsulphonyl at the same time; R1 = H or a (substd.) 1-4C alkyl or cycloaliphatic gp.; R2 = R1 a (substd.) benzyl, naphthyl or hetaryl gp., a (substd.) phenyl gp. free from SO3H or SO2X gps. or a (substd.) amino gp.
