Abstract

The new azo dyes corresponding to the general formula (I) in which D1 is a benzene, naphthalene or heterocyclic residue, D2 is a benzene or naphthalene residue, n = 0 or 1, X1 and X2 denote optional substituents, R1 denotes a hydrogen atom or an optionally substituted alkyl radical, R2 denotes an optionally substituted alkylene radical, R3 and R4 denote an alkyl radical, are obtained either directly by azo coupling or by azo coupling and esterification by means of a halide of an N,N-dialkylsulphamic acid. The dyes of formula (II) are particularly suitable for the dyeing and printing of natural and synthetic polyamide fibres. <IMAGE>
