Azo dyes containing triazine middle components and a 1,4-phenylene-2,5-disubstituted coupling component

U.S. Patent Number: 5328995

Abstract: The compounds of the formula ##STR1## where the substituents are as defined in claim 1, are direct dyes for various substrates, in particular cellulosic fibre materials. They are high temperature resistant and therefore are particularly highly suitable for the one-bath, single-stage dyeing of polyester/cotton blend fabrics with a disperse dye for the polyester fibres under the dyeing conditions for polyester fibres.
