Abstract

DC60 (19/07/42) This invention reveals a dye mixture consisting of one or more azo dyes (1) and one or more azo dyes (2) or (3) or (2) and (3), all of which contain a 1-(halotriazinalamino)-3,6- or 4-,6-disulfo-8-naphthol coupling component and a third substituent in the triazine portion of (1) and, as well as of (2) and (3), are selectively substituted as alkyl- and/or phenyl- or heterocyclic amino radicals, and the diazo component in (1) contains a fiber-reactive group of The dye mixtures are either vinyl sulfone radicals and are selectively substituted as alkyl- and/or alkoxy- or selectively substituted as sulfo-naphthyl radicals, in (2) they are selectively substituted as alkyl, alkoxy, chlorine, bromine, sulfo, and/or carboxyl radicals or selectively substituted as sulfo-naphthyl radicals, and in (3) they are sulfophenyl radicals linked via amino groups, with reactive halopyrimidine radicals or halotriazine radicals with reactive vinyl sulfone groups. The dye mixtures are particularly useful for dyeing materials containing hydroxyl and/or carboxamido, especially fibrous materials, in deep bluish-red to yellowish-red shades.
