ABSTRACT:
The object of the present invention is to provide an optical recording medium in which a recording material of the optical recording medium has a high solubility in an organic solvent, so that the recording material can be shaped to film by a coating process and the recording material is excellent in light-resistance and stability during the preservation, so that the optical recording medium is applicable to the recordable DVD. For the object, the present invention provides the optical recording medium comprising a substrate and at least a recording medium disposed on the substrate, wherein the recording medium comprises at least one type of formazan-metal chelate dyes.
