    • This invention relates to direct dyes for various substrates, in particular cellulosic fiber materials. The inventive dyes are high-temperature-resistant and highly suitable for the single bath, one step dyeing of polyester/cotton mixed fabrics with a disperse dye for the polyester fibers under the dyeing conditions for polyester fibers.The inventive dyes are of the formula ##STR1## in which A is a radical of the formula ##STR2## A' has the meaning of A or is a mono- or polyazo dye radical which is different from A, R and R', independently of one another, are hydrogen or C.sub.1 -C.sub.4 alkyl which is unsubstituted or substituted by chlorine, hydroxyl, cyano, carboxyl, sulfo, sulfato, methoxy, ethoxy, methoxycarbonyl or ethoxycarbonyl, R.sub.1 is hydroxyl, C.sub.1 -C.sub.4 alkoxy, halogen, C.sub.1 -C.sub.4 alkylthio, amino, N-mono- or N,N-di-C.sub.1 -C.sub.4 alkylamino which is unsubstituted or substituted in the alkyl moiety by hydroxyl, carboxyl or C.sub.1 -C.sub.4 alkoxy, cyclohexylamino, phenylamino or N-C.sub.1 -C.sub.4 alkyl-N-phenylamino which are unsubstituted or substituted in the phenyl moiety by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, carboxyl, sulfo or halogen, morpholino, piperidino or 3-carboxy- or 3-carboxamidopyridin-1-yl, R.sub.2 is unsubstituted or hydroxy-substituted C.sub.1 -C.sub.4 alkyl, and the phenyl radical (a) is unsubstituted or substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, hydroxyl, carboxyl, sulfo, --NHCOR.sub.2 or unsubstituted or sulfo-, C.sub.1 -C.sub.4 alkoxy-, hydroxyl- or halogen-substituted phenylazo or 1-2-naphthylazo.
