ABSTRACT:
An optical recording medium that contains a monomolecular film or a lamination of monomolecular films having polydiacetylenic bonds is provided. The monomolecular film is prepared by adsorbing a chemical adsorbent having a diacetylene group, and a --SiCl group at one molecular end on a base plate, and irradiating said monomolecular film with ultraviolet rays to polymerize the adsorbents at the diacetylene group, thereby forming polydiacetylenic bonds. The resulting blue monomolecular film or the lamination will turn red by the application of light or heat, reversibly or irreversibly.
