摘要:
The optical recording medium comprises a visible information recording layer comprising at least two dyes of the following dyes. Ra1 to Rb3 each independently denote a hydrogen atom or a monovalent substituent, Ra2 and Ra3 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. In general formula (II), Rα1 to Rα8 and Rβ1 to Rβ8 each independently denote a hydrogen atom or a monovalent substituent, M denotes two hydrogen atoms, a metal, a metal oxide, or a metal having a ligand. A1═N—B1 General formula (III) A1 denotes a substituted or unsubstituted heterocyclic group, a substituted aliphatic group, or a substituted or unsubstituted carbocyclic group, and B1 denotes a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted aryl group.
