Zusammenfassung:	An optical recording medium which comprises a substrate and a recording layer provided on the substrate by using a specific organic dye compound having absorption maximum in a region with wavelengths longer than that of a writing light used, and which records information by allowing to irradiate the recording layer with the writing light to act on the benzoindolenine styryl dye compound to form a pit on the substrate.An optical recording medium which comprises a substrate and a recording layer provided on the substrate by using a specific organic dye compound having absorption maximum in a region with wavelengths longer than that of a writing light used, and which records information by allowing to irradiate the recording layer with the writing light to act on the benzoindolenine styryl dye compound to form a pit on the substrate.
