Disazo dyestuffs containing the {60 :{62 -dichloro- or {60 :{62 -dibromopropionylamino group

Abstract

Abstract Fibre-reactive disazo dyestuffs containing at least two and at most four sulphonic acid groups and at least one and at most two aromatically bound Alpha : Beta -dichloro- or Alpha : Beta dibromopropionylamino groups correspond to the formula WHEREIN R is an o-sulfobenzene radical which may be further substituted by lower alkyl, lower alkoxy, trifluoromethyl, chlorine or bromine, one X is hydrogen and the other X is a sulfonic acid group and R2 is a benzene radical which may be substituted by lower alkyl, lower alkoxy, trifluoromethyl, chlorine, bromine, sulfo or nitro. These dyestuffs yield brilliant dyeings of excellent general fastness-properties on cotton.
