ABSTRACT:
A water-soluble monoazo-dyestuff having in form of the free acid the formula ##STR1## WHEREIN A represents as a radical of a diazo component phenyl; phenyl substituted by lower alkyl, lower alkylsulfonyl, lower alkoxy, carboxyl, trifluoromethyl, cyano, fluorine, chlorine, bromine, sulfonamido and carbonamido; naphthyl, nitronaphthylene, ##STR2## X represents hydrogen; phenyl; nitrophenylene or naphthyl, R represents as a bridging member --SO.sub.2 --, --CO--, --S--, --CO--NH--, --NH--CO--, --SO.sub.2 --NH--, --NH--SO.sub.2 --, --CH.sub.2 --, --NH-- or --N(lower alkyl)--; B represents as the radical of a coupling component N,N-di(lower alkyl)amino-phenylene, N,N-di (lower alkyl)amino-chloro-phenylene; hydroxyquinoline; diphenylamine; hydroxynaphthylene; hydroxynaphthylene substituted by acetylamino, benzoylamino or ##STR3## aminonaphthylene; ##STR4## substituted on the benzene nucleus by lower alkyl, lower alkoxy, chlorine and bromine; Z represents hydrogen, --COOH or --SO.sub.3 H, Y represents a direct linkage or one of the groupings --CH.sub.2 --, --CH.sub.2 13 CH.sub.2 --, --NH-- or --N(lower alkyl)--, the said groupings --Y--SO.sub.2 --CH.sub.2 --CH.sub.2 --O--PO.sub.3 H.sub.2 and Z being linked to A, B or X, n stands for an integer from 1 to 3 and m stands for an integer from 1 to 5, said dyestuffs being suitable for the dyeing or printing of leather or fibrous materials consisting of native or regenerated cellulose, wool, silk or polyamides, the dyeings and prints obtained on said materials being distinguished by deep tints and very good fastness properties to light and wetting.
