Abstract
The invention discloses novel basic dioxazine compounds of the formula ##STR1## wherein each of X.sub.1 and X.sub.2 independently is an unbranched or branched alkyl group of 1 to 4 carbon atoms, an unsubstituted or substituted phenyl group, halogen, hydrogen, cyano, a phenylamino group which is unsubstituted or substituted in the phenyl nucleus, the CONH.sub.2 group, the CONH-phenyl group which can be substituted in the phenyl moiety, or a COO--C.sub.1 -C.sub.4 alkyl group; Z is a non-quaternized or quaternized basic group, Y is an anionic group, each B independently is a fused ring system containing 2 to 4 carbocyclic and/or heterocyclic rings and which, in addition to containing the substituents Z and Y, can be further substituted; n is 1 to 4 and m is 0 to 2, with the proviso that m is not greater than n. Processes for obtaining these compounds and their use as dyes for coloring and printing in particular cellulosic fabrics, without the addition of salt, are also disclosed.
