摘要:
Azo dyes having 2,6-diaminopyridine derivatives as coupling components which preferably bear cyano or carbamoyl as substituents in the 3-position. The dyes give brilliant yellow to blue colorations, particularly on synthetic polyesters, which are distinguished by outstanding fastness properties.
