Abstract
The invention comprises monoazo dyestuffs which, in the form of the free acids, have the general formula <FORM:0881737/IV (c)/1> in which A is a b -halogenated propionyl group, D is a benzene residue containing no hydroxyl group in O-position to the azo linkage, one X is hydrogen, and the other X is an R-CO-NH- group in which R is a free amino group or the residue of an aliphatic alcohol containing at most 3 carbon atoms and bound through its oxygen atom. The dyestuffs may be made by coupling a diazo compound of an amine of formula A-NH-D-NH2 with an appropriate naphthol compound. Specified coupling components are 2 - ureido - 8 - hydroxy - naphthalene - 6 - sulphonic acid, 2-ureido-5-hydroxynaphthalene-7-sulphonic acid, and 2-amino-5-hydroxynaphthalene-7-sulphonic acids of which the amino group is bound through a -CO-bridge to the oxygen atom of an alkoxy group, e.g. to a methoxy or ethoxy group or to a group of the formula -OC2H4OCH3. Specified amines from which the diazo components are formed are 4- and 5-(b -bromo and chloro-propionylamino)-2-amino-benzene-1-sulphonic acid. The coupling is preferably carried out in an alkaline medium. If desired, the dyestuffs of the invention may be obtained by subjecting a dyestuff of the formula <FORM:0881737/IV (c)/2> to acylation with the anhydride or a halide of a b -halogenated propionic acid, preferably in the presence of an acid-binding agent such as sodium acetate or sodium carbonate. In an example, diazotised 5-nitro-2-amino-benzene-1-sulphonic acid is coupled with 6-ureido-1-hydroxynaphthalene-3-sulphonic acid, the nitro group is then reduced to an amino group, and the amino-azo dye thus obtained is acylated with b -bromopropionyl chloride. The dyestuffs may be isolated by salting out and filtration. In some cases the whole mixture in which the dye is prepared may be spray dried. The dyes may be used for dyeing and printing cotton, linen, viscose, silk, wool, leather, polyurethane, and polyamide fibres, and the dyeings may be fixed by heat treatment in the presence of alkali.
