Abstract: Azo metal chelate dyes matching the semiconductor laser with short wavelength of 635~650 nm were synthesized. The UV-Vis absorption spectra of an azo dye and its metal complexes were measured, the stiochiometry of the azo dye metal complexes were determinated by spectroscopic titration method. TG-DTA analysis show a clear threshold of thermal decomposition with sharp exothermic peak. This azo metal chelate dye is suitable for optical recording medium.

Key words: azo metal chelate dye, optical recording medium, complex formation, thermal properties
