Synthesis of azo dyes from 6-amino-2-methoxy-quinoxaline and their use as disperse dyes for polyester fibres

6-Amino-2-methoxyqumoxaline (5) was sy nthe sise d from quinoxal-2-one (1) and used as diazo component as well as coupling component in the synthesis of azo dyes which were applied on polyester fibres as disperse dyes. The spectral properties and evaluation of the dyes are discussed.
