Abstract
Valuable reactive dyestuffs containing no acid, salt-forming, water-solubilizing groups and which, among others, can be applied from organic solvents, especially aprotic solvents correspond to the formula ##EQU1## wherein D represents the radical of an organic dyestuff, PA1 Q represents the bridging member --NX.sub.3 --, --O--, --S-- or --NX.sub.3 CO--, whereby X.sub.3 denotes hydrogen or a lower alkyl group, PA1 R represents the radical of a nitrogen heterocycle containing at least one substituent which can be split off as anion and which is bound to a ring carbon atom adjacent to a tertiary nitrogen atom, PA1 X.sub.1 represents hydrogen, an alkyl or an alkoxyalkyl group and PA1 X.sub.2 represents an alkyl or an alkoxyalkyl group having in all at least 4 carbon atoms, whereby X.sub.1 and X.sub.2 must together contain, when X.sub.1 denotes an alkyl or an alkoxyalkyl group, at least 8 carbon atoms, Or PA1 X.sub.1 represents a cyclohexyl radical, unsubstituted or substituted by lower alkyl groups having preferably 1 to 4 carbon atoms, and PA1 X.sub.2 represents an unsubstituted or substituted alkyl group having at most 18 carbon atoms, a lower alkenyl group having preferably 1 to 4 c…
