Özet

A series of new heterocyclic disperse azo dyes was prepared by coupling selected diazotized heterocyclic amines with 6-aminouracil. Solvent effects on the UV-visible spectra of the dyes were evaluated. Their colors were discussed with respect to the nature of the heterocyclic ring and the substituents, and the effects of acid and base on their UV-visible absorption spectra.
