Zusammenfassung:Chromium complex dyestuffs of the formula wherein X denotes hydrogen or nitro, Y denotes hydrogen, nitro or chlorine and Z denotes hydrogen, nitro, chlorine, alkyl, alkoxy, alkylsulphonyl, arylsulphonyl or SO2NW1W2 and W1 and W2 denote hydrogen, aryl or alkyl, with the proviso that Y and Z do not simultaneously represent nitro, are particularly suitable for dyeing polyamides and wool, on which they produce level dyeings having good general fastness properties.
