    • Described are dye mixtures comprising one or more azo dyes (1) and one or more azo dyes (2) or (3) or (2) and (3), all these azo dyes containing a 1-(halotriazinylamino)-3,6- or -4,6-disulfo-8-naphthol coupling component and the third substituent in the triazine moiety of (1) and similarly of (2) and of (3) being an optionally alkyl- and/or phenyl-substituted amino radical or heterocyclic radical and the diazo component in (1) containing a fiber-reactive group of the vinyl sulfone series and being an optionally alkyl- and/or alkoxy-substituted phenyl or optionally sulfo-substituted naphthyl radical, in (2) being an optionally alkyl-, alkoxy-, chlorine-, bromine-, sulfo- and/or carboxyl-substituted phenyl or optionally sulfo-substituted naphthyl radical and in (3) being a sulfophenyl radical which, attached via an amino group, possesses a fiber-reactive halopyrimidine radical or a halotriazine radical having a fiber-reactive group of the vinyl sulfone series. The dye mixtures are very useful for dyeing hydroxyl- and/or carboxamido-containing materials, especially fiber materials, in deep bluish to yellowish red shades.
    • 描述了包含一种或多种偶氮染料(1)和一种或多种偶氮染料(2)或(3)或(2)和(3)的染料混合物,所有这些偶氮染料含有1-(卤代三嗪基氨基)-3,6 - 或-4,6-二磺基-8-萘酚偶联组分和(1)和类似(2)和(3)的三嗪部分中的第三取代基是任选的烷基 - 和/或苯基取代的氨基 或(2)中任选地含有乙烯基砜系列的纤维反应性基团和任选地烷基 - 和/或烷氧基取代的苯基或任选的磺基取代的萘基的(1)中的重氮组分, 烷基 - ,烷氧基 - ,氯 - ,溴 - ,磺 - 和/或羧基取代的苯基或任选的磺基取代的萘基,并且在(3)中是通过氨基连接的具有纤维反应性 卤代嘧啶基或具有乙烯基砜系列的纤维反应性基团的卤代三嗪基。 染料混合物对于深蓝色至黄色红色色调的含羟基和/或羧酰胺基材料,特别是纤维材料的染色非常有用。
