Abstract

Novel compounds of the general formula I ##STR1## where A is a fiber-reactive radical of the triazine, pyrimidine or vinylsulfone series, D is a radical of a sulfo-containing diazo component of the aniline or aminonaphthalene series, K is the radical of a coupling component of the aminohydroxynaphthalene series, X is fluorine, chlorine, bromine, C.sub.1 -C.sub.4 -alkyl, trifluoromethyl, C.sub.1 -C.sub.4 -alkoxy, phenoxy, hydroxysulfonyl, carboxyl, acetyl, propionyl, methylsulfonyl, ethylsulfonyl, phenylsulfonyl, C.sub.1 -C.sub.4 -alkoxycarbonyl, phenoxysulfonyl or unsubstituted or substituted carbamyl or sulfamyl, and Y is fluorine, chlorine, bromine, C.sub.1 -C.sub.4 -alkyl, trifluoromethyl, C.sub.1 -C.sub.4 -alkoxy, phenoxy, phenoxysulfonyl, acetyl, propionyl, methylsulfonyl, ethylsulfonyl, phenylsulfonyl, p-acetylaminophenylsulfonyl, hydroxysulfonyl, C.sub.1 -C.sub.4 -alkoxycarbonyl, hydroxycarbonyl or unsubstituted or substituted carbamyl or sulfamyl, are very useful for dyeing wool and hydroxyl-containing fibers, such as cellulose and in particular cotton.
