An optical recording medium containing one or more compounds selected from imide compounds having a metallocene residue in a recording layer and an imide compound represented by a general formula (1):
wherein a ring AR represents a substituted or unsubstituted aromatic ring residue or a residue formed by combining two or more aromatic ring residues via one or more linking groups; n represents the number of imide groups bonded to the ring AR; A
m
represents any one of substituents A
1
to A
n
bonded to a nitrogen atom of each imide group; and m represents an integer of from 1 to n, with the proviso that at least one substituent selected from the group consisting of A
1
to A
n
is one having at least one substituted or unsubstituted metallocene residue.
