1. A monoazo dye of the formula see diagramm : EP0101664,P35,F1 in which K is the radical of an aminobenzene, alkoxybenzene, alkoxynaphthalene, naphthol, aminonaphthol, pyrazolone, aminopyrazole, indole, naphthimidazole, diphenylamine, tetrahydroquinoline or acetoacetamide, which radicals may be further substituted, R is hydrogen, halogen, C1-6 -alkyl, trifluoromethyl, carboxyl or an -SO2 -C1-6 -alkyl, -SO2 R1 , - SO2 NR2 R3 , CONR2 R3 ; or -CO-R4 group, in which R1 is substituted or unsubstituted phenyl- or naphthyl-C1-4 alkyl radical, each of R2 and R3 independently of the other is hydrogen or a substituted or unsubstituted C1-6 alkyl or C5-7 cycloalkyl radical and R4 is a substituted or unsubstituted phenyl radical, and X is hydrogen, C1-4 alkyl, C1-4 -alkoxy or halogen, with the proviso that R in formula (1) may not be hydrogen or chlorine if the radical -N=N-K is bonded to the phenyl ring in the o-position relative to the -SO2 - group and K is the radical of 2-amino-8-hydroxynaphthalene-6-sulfonic acid, and that R in formula (1) may not be hydrogen if the radical -N=N-K is bonded to the phenyl ring in the o-position relative to the -SO2 group and K is the radical of 1-(3',4'-dichlorophenyl)-3-methyl-5-aminopyrazole or of an aminonaphtholsulfonamide. |
