摘要：
Reactive dyestuffs which, as the free acid, have the following formula ##STR1## in which K is ##STR2## the bonding to the triazinyl radical taking place in each case via the amino function of K, and the remaining substituents have the meaning given in the description, are suitable in particular for the dyeing and printing of natural and synthetic OH- and/or amido-containing materials.
