| 摘要 |
The invention provides an optical information recording medium having at least a substrate and a recording layer capable of recording information provided on the substrate. The recording layer contains at least a metal complex compound obtained by forming a salt from a cationic part and an anionic part, and the cationic part being a cation of a metal complex having a molar absorbance coefficient (∈) in the wavelength range of 350 to 1300 nm of 10,000 dm3 mol-1 cm-1 or less when an anionic part is any one of Cl-, Br-, I-, ClO4-, PF6-, BF4-, SO42-, or CF3SO3-. A thermal decomposition temperature of the metal complex is preferably 250° C. or higher when an anionic part of any one of Cl-, Br-, I-, ClO4-, PF6-, BF4-, SO42-, or CF3SO3-.
