Azo dyes with 2,6-diamino-pyridine coupling component
摘要：
Azo dyes having a 2,6-diamino-pyridine as coupling component, one of the amino groups bearing a bicyclic or polycyclic non-aromatic radical as a substituent. The dyes are eminently suitable as disperse dyes, particularly for synthetic linear polyesters, and give bright dyeings having excellent fastness properties.
摘要（中）：

具有2,6-二氨基 - 吡啶作为偶联组分的偶氮染料，其中一个氨基具有双环或多环非芳族基团作为取代基。 该染料特别适用于分散染料，特别适用于合成线性聚酯，并得到具有优异牢度性能的光亮染色。
