ABSTRACT:
Dyes of the formula ##STR1## wherein K is the radical of a coupling component which can additionally contain azo groups, R is hydrogen or methyl, and Z is a fluorine atom, a substituted or unsubstituted amino group, a substituted or unsubstituted hydroxyl group, a substituted or unsubstituted mercapto group, or a substituted or unsubstituted hydrocarbon radical are distinguished by high reactivity and they produce dyeings of good wet- and light-fastness properties. The dyes of the Formula (I) are suitable for dyeing and printing a very wide variety of materials, such as silk, leather, wool, polyamide and polyurethane fibres, and especially cellulosic materials of fibrous structure, such as liner, cellulose, regenerated cellulose, and in particular cotton. They are suitable both for the exhaust method and for dyeing by the pad-dyeing process. They are also suitable for printing, in particular on cotton.
