摘要：

The paper presents a class of mono- and dis- azo dyes, derivatives of 4-amino-5-hydroxy-2,7naphtalenedisulfonic acid ("H acid"). These dyes were obtained by the azo coupling reaction of "H acid" with the diazonium salt of primary aromatic amines, in alkali or acid media. IR, UV-VIS, H-1-NMR spectroscopy and elemental analysis characterized the structure of synthesized compounds.
