Water-soluble disazo compounds, process for their preparation and their

Abstract

Water-soluble fiber-reactive disazo compounds of the formula (1) given and defined below are described, which compounds serve as dyes for dyeing and printing hydroxy- and/or carboxamido-containing material, in particular fiber material, such as wool and synthetic polyamide and, in particular, cellulose fiber materials, such as cotton. ##STR1## In this formula M is hydrogen or an alkali metal, the groups Y--SO.sub.2 -- and --SO.sub.2 --Y.sup.0 are fiber-reactive groups from the vinylsulfone series, m is 1 or 2, n is zero or 1, R is a group of the formula (2) or (3) ##STR2## in which R.sup.A is lower alkyl which may be substituted, or is phenyl which may be substituted by sulfo, carboxy, lower alkyl and/or lower alkoxy, X is chlorine, fluorine, hydroxy, alkoxy, cycloalkoxy or alkoxy of 3 to 8 carbon atoms whose alkyl radical is interrupted by --O--, --NH--, --CO--NH-- or --NH--CO--, or is benzyloxy, sulfomethoxy, .beta.-sulfoethoxy, amino, alkylamino, cycloalkylamino or alkylamino of 3 to 8 carbon atoms whose alkyl radical is interrupted by one of the abovementioned hereto groups, or is benzylamino, sulfomethylamino, .beta.-sulfoethylamino or cyanoamino, Z is chlorine, fluorine or a group of the formula (4a) (4b), (4c) (4d) ##STR3## in which alk is alkylene which is interrupted by one or two of the abovementioned hetero groups, the group --SO.sub.2 ---Y.sup.1 is a fiber-reactive group from the vinylsulfonyl series, R.sup.1 is hydrogen, carboxy, sulfo or a fiber-reactive group from the vinylsulfone series, R.sup.2 is hydrogen, lower alkyl, lower alkoxy, chlorine, bromine, carboxy, sulfo or nitro, R.sup.3 is hydrogen, lower alkyl, lower alkoxy, chlorine, bromine, carboxy or sulfo, and p is 1 or 2.
