Description:
Reactive dyestuffs which contain two triazine or pyrimidine radicals bonded to each other through a diamine are known.
In these dyestuffs there is always present a more or less large bridge member between the reactive radicals, and both reactive radicals are bonded to different nitrogen atoms.
The invention is based on the surprising discovery that it is possible to manufacture reactive dyestuffs which contain two triazine radicals which are bonded to each other through a single amino group, so that both reactive radicals are linked to the same nitrogen atom.
The present invention therefore relates to dyestuffs which contain two fibre-reactive triazine radicals which are bonded to each other through the nitrogen atom of an amino group.
The third substituent at the nitrogen atom of the amino group, which bonds the two reactive radicals to each other, may be a hydrogen atom or another radical, in particular an aliphatic or aromatic radical, preferably a low molecular alkyl radical, for example a methyl,
