ABSTRACT:
The invention relates to reactive dyes of the formula ##STR1## wherein D is the radical of a diazo component, R.sub.1 and R.sub.2 are each independently an unsubstituted or substituted alkyl or alkenyl group, Y is a --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 --X radical in which X is a fibre-reactive radical, and the benzene ring A may be further substituted. These dyes are suitable for dyeing and printing textile fibre material and yield dyeings and prints of good fastness properties.
