Abstract: Disclosed is an optical recording medium, comprising a polymer alloy forming a phase-separated domain structure of a coating object, and a volatile substance interacting with the polymer alloy. The volatile substance in a vapor state is deposited on the surface of specific phase-separated domain, and dispersedly infiltrated into the phase-separated domain. The phase-separated domain and the volatile substance chemically interact with each other. The optical recording medium is operable to perform optical recording by utilizing change in the transmittance, reflectance, refractive index or surface potential thereof in response to irradiation of ultraviolet light, visible light, or infrared light from outside. The present invention can provide an optical recording medium suitable for high-density recording in a wide wavelength range.
