  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.
