Optical recording medium and method of recording visible information

An optical recording medium comprising a visible information recording layer on a support, wherein said visible information recording layer comprises at least two dyes selected from the group consisting of a dye denoted by general formula (I), a dye denoted by general formula (II), and a dye denoted by general formula (III).

• In general formula (I), Ra1, Ra2, Ra3, Rb1, Rb2, and 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, and plural Rb2s and Rb3s may be identical or different from each other when n is equal to or greater than 2.
• In general formula (II), Za21 and Za22 each independently denote an atom group forming an acidic nucleus, Ma21, Ma22, and Ma23 each independently denote a substituted or unsubstituted methine group, Ka21 denotes an integer ranging from 0 to 3, plural Ma21s and Ma22s may be identical or different from each other when Ka21 is 2 or 3, and Q denotes a monovalent cation.
• A1=N—B1 General formula (III)
• In general formula (III), A1 denotes a substituted or unsubstituted heterocyclic group, a substituted aliphatic group, or a substituted or unsubstituted carbocyclic group, and B denotes a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted aryl group.
