  The optical recording medium comprises a visible information recording layer comprising at least two dyes of the following dyes. R a1 to R b3 each independently denote a hydrogen atom or a monovalent substituent, R a2 and R a3 may bond together to form a five to seven-membered heterocyclic ring, A denotes a substituted or unsubstituted aliphatic group, substituted or unsubstituted aryl group, or substituted or unsubstituted heterocyclic group, n denotes 0, 1, 2, or 3. Za 21 and Za 22 each independently denote an atom group forming an acidic nucleus, Ma 21 to Ma 23 each independently denote a substituted or unsubstituted methine group, Ka 21 denotes an integer ranging from 0 to 3, and Q denotes a monovalent cation. A 1 =N—B 1 General formula (III) A 1 denotes a substituted or unsubstituted heterocyclic group, a substituted aliphatic group, or a substituted or unsubstituted carbocyclic group, and B 1 denotes a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted aryl group.

  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 dm 3 mol −1 cm −1 or less when an anionic part is any one of Cl − , Br − , I − , ClO 4 − , PF 6 − , BF 4 − , SO 4 2− , or CF 3 SO 3 − . 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 − , ClO 4 − , PF 6 − , BF 4 − , SO 4 2− , or CF 3 SO 3 − .
