Abstract

The present invention relates to mixtures of dyes of the general formula I ##STR1## in which R.sup.1 is hydrogen, halogen, (C.sub.1 -C.sub.4) -alkyl or (C.sub.1 -C.sub.4)-alkoxy; PA1 R.sup.2 is hydrogen, halogen, cyano, (C.sub.1 -C.sub.4)-alkyl, (C.sub.1 -C.sub.4)-alkoxy, (C.sub.1 -C.sub.4)-alkoxycarbonyl, (C.sub.1 -C.sub.4)-alkylcarbonyloxy or phenyl, which may be substituted or unsubstituted; PA1 R.sup.3 is hydrogen, (C.sub.1 -C.sub.4)-alkyl, (C.sub.1 -C.sub.4)-alkoxy or phenyl, which may be substituted or unsubstituted; and PA1 R.sup.4 is hydrogen, halogen, (C.sub.1 -C.sub.4)-alkoxy, phenylthio or phenoxy, which may be substituted or unsubstituted, to processes for their preparation and to the use of the dyes of the general formula I and their mixtures with one another for the dyeing and printing of textile hydrophobic synthetic fibre materials and blends thereof with natural fibre materials.
