Abstract

Water-soluble monoazo dyes which, in the form of the free acids, have the formula: <IMAGE> wherein X represents an alkylene radical having from 1 to 6 carbon atoms, Y represents an arylene radical, n is 0 or 1, ring A may carry further non-ionic substituents and E represents the residue of a coupling component. The dyes are applicable as acid dyes to natural and synthetic polyamide textile materials.
