Abstract

Navy mixtures which contain dyes of the formula I ##STR1## where X is chlorine or bromine, PA0 Y is hydrogen, methoxy or ethoxy and PA0 R is N(C.sub.2 H.sub.5).sub.2, N(CH.sub.2 CH.dbd.CH.sub.2).sub.2 or N(C.sub.2 H.sub.4 OCOCH.sub.3).sub.2, the mixtures being composed of 10-70% of dyes with Y.dbd.H and R=N(C.sub.2 H.sub.5).sub.2, 5-40% of dyes with Y=OCH.sub.3 or OC.sub.2 H.sub.5 and R.dbd.N(CH.sub.2 --CH.dbd.CH.sub.2).sub.2 and 5-80% of dyes with Y=OCH.sub.3 or OC.sub.2 H.sub.5 and R=N(C.sub.2 H.sub.4 OCOCH.sub.3).sub.2. The novel mixtures have excellent tinctorial properties and give very fast dyeings on synthetic polyesters.
