An optical recording material used in an optical recording medium which can record information by light irradiation, this optical recording material containing a dye compound obtained by salt formation between a chelate compound formed by coordination between one metal and one or two compounds represented by the following general formula (1): €ƒ€ƒ€ƒ
where A and B are groups of atoms which may be identical or different, and which respectively form aromatic rings, and X 1 and X 2 are respectively functional groups having one or more active hydrogen atoms which may contain a substituent group,
€ƒ€ƒ€ƒand a cation represented by the following general formula (2): €ƒ€ƒ€ƒ
where C is a group of atoms forming a benzene ring or naphthalene ring which may have a substituent group, R 1 and R 2 are respectively five-membered rings or six-membered rings which may have a substituent group, Y 1 is a substituent group, Q 3 is a nitrogen-containing heterocyclic ring which may have a condensed ring, p and q are respectively integers from 1 to 4, and n is an integer from 0 to 3.
