    Abstract: Disazo compounds conforming to the general formula (1) below and suitable for use as fiber-reactive dyes for the dyeing of carboxamido-containing and/or hydroxy-containing materials such as wool and, in particular, cellulose fiber materials, in navy hues having good fastness properties (1) in which M is a hydrogen atom or an alkali metal or alkaline earth metal, D1 is a phenyl radical which can be substituted by substituents from the group consisting of chlorine, bromine, sulfo, alkyl and alkoxy and additionally by a vinylsulfonyl or beta -sulfatoethylsulfonyl group or by a group of the general formula (3) (3) where X is a vinyl or beta -sulfatoethyl group; D2 is a radical of the general formula (4) (4) in which M and X have one of the abovementioned meanings and the amino group -NH- is bound to the benzene ring in the para-position with respect to the sulfo group -SO3M or in the paara-position with respect to the free bond.
