Disazo dyes were derived from heterocyclic amines by diazotizing 2-Amino-6-nitrobenzothiazole, 2-Amino-5-nitrothiazole, and 2-Amino-3,5-dinitrothiophene and coupling with Aniline as middle components, and 1-Naphthylamine, N,N-Dimethyl-1-naphthylamine, N,N-Dibutylaniline and N,N-Diethylaniline, Aniline as final components. Disazo red, violet, blue dyes were synthesized and the absorption bands of these compounds were observed in the range of 512-668nm. The effects of diazo components and final coupling components on the visible absorption maxima of the dyes were also discussed.
