<p>An optical recording medium in which deposition of impurities or damage to a surface of the medium illuminated by the light for signal recording and/or reproduction is to be prevented from occurring. An amine salt compound of perfluoropolyether having terminal carboxylic groups, represented by the chemical formulas (1) and/or (2): Rf-COO<->N<+>HR1R2R3 R1R2R3N<+>H<->CO-Rf-COO<->N<+>HR1R2R3 where Rf denotes a perfluoropolyether group and R1, R2 and R3 denote hydrogen or a hydrocarbon group, is held on the surface side illuminated by light. <IMAGE></p> |
