Abstract

The preparation is described of reactive azo dyes of the formula I by condensing appropriate azo dyes of the formula XI with a reactive component X-Z. In the formulae R is optionally substituted alkyl, R1 is hydrogen or optionally substituted alkyl, W is a direct bond or bridge member, A is the radical of a coupling component, and Z is the radical of a heterocyclic reactive component of the formula -CO-Het, -SO2-Het or <IMAGE> where Het is a heterocycle attached directly or via a bridge member and the monocyclic or polycyclic heterocycles Het and <IMAGE> have at least one substituent that is reactive with cellulose or polyamide. The dyes mentioned are suitable in particular for dyeing and printing hydroxyl- or amido-containing materials and for the wash-fast dyeing and printing of native and regenerated cellulose. <IMAGE>
