Abstract

Triphendioxazine compounds corresponding to the formula ##STR1## which are suitable as fiber-reactive dyestuffs for dyeing and printing material, in particular fiber material, containing hydroxy and/or carboxamide groups, such as wool and synthetic polyamide fibers, and especially cellulose fibers, such as cotton, are described. In formula (1), M is hydrogen or an alkali metal and Z is a radical of the formula (2) ##STR2## in which R is hydrogen, sulfo, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, nitro or cyano, W is alkylene having 3 to 6 carbon atoms and the group --SO.sub.2 --Y is a fiber-reactive group of the vinyl sulfone series.
