Abstract

Reactive dyestuffs which are free from anionic groups, in particular sulpho and carboxyl groups, and contain a basic group and a halogenotriazinyl radical, and their use for dyeing and printing synthetic fibre materials. The dyeing obtained are distinguished by good fastness properties, of which, in addition to fastness to sublimation, light and dry cleaning, fastness to wet processing is to be singled out in particular.
