<p>An organic compound which, when applied to an organic dye compound, can improve the light resistance without substantially impairing its desirable optical properties and which is excellent in solubility in organic solvents and compatibility with dyes. It is a formazan metal complex containing a specific formazan compound as a ligand. Also provided are: a process for producing the formazan metal complex; a light resistance improver comprising the formazan metal complex; an optical recording medium; a light absorber; and a formazan compound as an intermediate for producing the formazan metal complex.</p> |
