2-氨基-5，10-二氢-10-羟基苯磷嗪10-氧化物是一种无诱变性的芳香胺，经重氮化后与各种磺化萘类偶联组分结合，得到了新的单偶氮染料，其结构经质谱和核磁共振分析得到证实。作为酸性染料的目标着色剂的性质的调查表明，他们提供深色调的羊毛和丝绸，这些染料只含有一个磺酸基团给黑色的羊毛色调在3%的omf深的阴影，而这些染料中的三个给蓝黑色的色调和一个给红黑色的色调的羊毛。四种色调的黑色类似于使用C. I.酸性黑1和所得的坚牢度性能通常良好。
2-Amino-5,10-dihydro-10-hydroxyphenophosphazine 10-oxide, a non-mutagenic aromatic amine, was diazotized and combined with various sulfonated naphthalene-based coupling components to give new monoazo dyes, the structures of which were confirmed using mass spectrometric and NMR analyses. Investigation of the properties of the target colorants as acid dyes indicated that they furnished deep shades on wool and silk; those dyes containing only one sulfonic acid group gave black shades on wool at 3% omf depth of shade whilst three of these dyes gave bluish-black shades and one gave a reddish-black shade on wool. The black color of the four shades was similar to that obtained using C.I. Acid Black 1 and the resultant fastness properties were generally good.
