式的本发明氨基偶氮化合物I 其中X和Y相同或不同，并代表氢，氯，溴，甲基，甲氧基，乙氧基，硝基，三氟甲基，甲氧羰基或乙氧羰基，A代表氢，甲基或乙基，且 Z是在杂芳族环系统的6-或7-位上是氢，氯或溴，甲基，甲氧基，乙氧基，甲氧羰基，乙氧羰基或硝基。 我被穿着式的类似物制备的式I化合物，取代有X和Y，monodiazotiertes对 - 二氨基苯与5-acetoacetylaminobenzimidazolone是基团A与式I，耦合的ž类似物。 对于X，Y或Z不是硝基，代替p型Diaminobenzolderivates的情况下，一个在2位和5位双取代的具有X和Y是用来对氨基 - 硝基苯衍生物。 在这种情况下，硝基化合物通过重氮化和偶联第一，其可通过还原被转化成式I的氨基偶氮化合物而获得 的氨基偶氮化合物被用作起始材料用于制备双偶氮化合物，优选二重氮颜料用过被重氮化以常规的方式，并且能够耦合化合物，例如的 被耦合到5-乙酰乙酰基氨基苯并咪唑酮。 由高着色强度，优异的溶剂和米特拉运输牢度性能和高的热稳定性ziechnen的双偶氮。

The invention aminoazo compounds of the formula in which X and Y are the same or different and are hydrogen, chlorine, bromine, methyl, methoxy, ethoxy, nitro, trifluoromethyl, carbomethoxy or carboethoxy mean, A represents hydrogen, methyl or ethyl, and Z in the 6- or 7-position of the heteroaromatic ring system hydrogen, chlorine or bromine, methyl, methoxy, ethoxy, carbomethoxy, carboethoxy or nitro. The compounds of formula 1 are prepared by carrying a with X and Y analog of the formula substituted, monodiazotiertes p-diaminobenzene with a 5-acetoacetylaminobenzimidazolone that the radicals A and Z analog of formula 1, couples. For the case that X, Y or Z is not a nitro group, a di-substituted with X and Y at the 2- and 5-position, p-amino-nitrobenzene derivative in place of the p-Diaminobenzolderivates. In this case, a nitro compound is obtained by diazotisation and coupling first, which can be converted by reduction into the aminoazo compound of the formula I. The aminoazo be used as starting materials for the production of disazo compounds, preferably disazo, being diazotized in the usual manner and coupled onto coupling-favoring compounds, eg 5-acetoacetyl aminobenzimidazolone. The disazo ziechnen by high color strength, excellent solvent and Mitra desk fastness properties and high thermal stability.
