Abstract Dye mixtures contain (a) 1-N-(2'-(3-substituted)-4'-chloro- or -fluoro–1',3',5'-triazin-6'-yl)-amino-7-(het)arylazo-8-hydroxy-3,6-di sulfonaphthalene dye(s) (I) and (b) other N-(2',4'-di-substituted)-1',3',5'-triazin-6'-yl)-amino- and/or N-(difluoro-pyrimidinyl)-amino-7-(het)arylazo-8-hydroxy-mono- or di-sulfo-naphthalene dye(s) (IIA-C). Dye mixtures contain (a) 1-N-(2'-(3-substituted)-4'-chloro- or -fluoro–1',3',5'-triazin-6'-yl)-amino-7-(het)arylazo-8-hydroxy-3,6-di sulfonaphthalene dye(s) (I) and (b) other N-(2',4'-di-substituted)-1',3',5'-triazin-6'-yl)-amino- and/or N-(difluoro-pyrimidinyl)-amino-7-(het)arylazo-8-hydroxy-mono- or di-sulfo-naphthalene dye(s) (IIA-C) of the formulae; D1, D2 = (het)aryl groups; D3, D4 = sulfophenyl or sulfonaphth-2-yl; X = OH, morpholino, (substituted) anilino (VA) or a vinylsulfonyl(alkyl)amino (precursor) group (VB, VC); Z1, Z2, Z3, Z4 = chlorine (Cl) or fluorine (F); or X = Z1 = Cl; R1 = OH, phenoxy, morpholino or (VA); or R1 = Z2 = Cl; R2 = (VA), (VB) or (VC); M = H or an alkali metal; p, p1, p2, p3 = 0 or 1. An Independent claim is also included for the preparation of the dye mixtures.
