Abstract
Abstract Triphendioxazine dyestuffs of the formula ##STR1## where the substitutents are as defined in the descriptive part, produce blue to reddish blue dyeings of good light and wet fastness on cellulose and polyamide materials. The new dyestuffs are obtained by oxidative cyclization of condensation products of appropriately substituted amines of the formula ##STR2## with 1,4-benzoquinones.
