Abstract

Process for the preparation of pure dyes of the dioxazine series, characterized in that a compound of the formula I is reacted ** (See formula) ** under conditions of ring closure and optionally in the presence of an acidic condensation agent, to form a triphenoxazine compound of the formula II ** (See formula) ** meaning in these formulas: X hydrogen, chlorine, bromine or the methyl group, R an unsubstituted phenyl group or a substituted non-ionogenic phenyl group and Hal chlorine or bromine.
