Abstract
The invention comprises dyes of formula <FORM:0922162/IV(a)/1> wherein x is a direct linkage or -O-, R1 and R2 are, p when x is -O- radicals of the benzene series which may be further substituted, or when x is a direct linkage, radicals of the benzene series which may be further substituted other than with sulphonamide or alkylsulphonamide radicals, and with the further exception that when R2 is substituted by -OH and -COOH these substituents are not in o-position with respect to each other, R3 is, when x is -O-, hydroxyl or, when x is a direct linkage hydroxyl or an amino group which may be mono- or di-substituted by unsulphonated organic radicals and R4 is hydrogen or alkyl which may be substituted, and wherein -N=N- is in o-position to R2-X-O2S- and the whole molecule contains one sulphonic acid group, other than the dyes wherein simultaneously R2 contains a sulphonic acid group, R3 is a substituted amino group and R4 is hydrogen. The dyes are prepared by conventional coupling procedures using o-substituted diazobenzenes and substituted 2-naphthylamine components. The dyes give orange to red shades on wool, silk, and synthetic polyamide fibres and leather. In examples the dyes 2-amino-41-methyl-1:11-diphenyl-sulphone-4-sulphonic acid --> 2-aminonaphthalene-5-sulphonic acid-n-nonylamide and 1-aminobenzene-2-sulphonic acid-(41-cyclohexyl)-phenyl ester --> 2-amino-naphthalene-5-sulphonic acid are prepared. Many further dyes are specified in examples. Specification 902,877 is referred to.
