Abstract

Procedure for the preparation of water soluble monoazo dyes of the general formulas **(See formula)** where Z represents a hydrogen atom, an optionally substituted aliphatic or aromatic acylamino group, or a sulfonamido group, n denotes the numbers 1 to 2, and X represents a hydrogen atom, the vinylsulfonyl radical, the beta-hydroxyethyl-sulfonyl radical or an ethylsulfonyl group substituted in beta position by organic or inorganic radicals capable of being separated in alkaline medium, in which in each case only one beta-substituted vinylsulfonyl or ethylsulfonyl group must be contained in the molecule, in which beta-naphthylamines are coupled diazotized of the formula **(See formula)** with coupling components of general formulas **(See formula)** in which X, Z and n have the meanings indicated above, and eventually in the monoazo dyes obtained from the general formulas (1a) (1b) the group X is transformed, when it has the meaning of the beta-bidroxyethylsulfonyl group, so as to yes known, either in the vinylsulfonyl group or in an ethylsulfonyl group substituted in beta position by organic or inorganic radicals capable of being separated in alkaline medium.
