Abstract :In this study, two formazans were synthesized by coupling cinnamaldehyde phenyl hydrazone which was obtained by activation of cinnamaldehyde with phenylhydrazone, with diazonium salts of anthranilic acid and sulfonilic acid. The complexes of Co +2 , Ni +2 , Cu 2+ salts of these formazans were also synthesized. These compounds were characterized by elemental analysis, infrared (IR), ultraviolet–visible (UV–vis), 1 H nuclear magnetic resonance ( 1 H-NMR) and  13 C-NMR spectra datas. Investigation of availability of these compounds as dyes were carried out for this purpose . In the present experimental approach, we applied two methods; The first one was direct dyeing with these complexes, and the other one was complex formation on the fibres. Finally, an investigation was carried out  for the fastness values (test) and it was found higher values, which was quite better and different from the other workers / researcher working in the same field.
