摘要： An optical information recording medium provided on a substrate thereof with a recording layer comprising a dye-containing layer, wherein the recording layer further comprises an organometallic dye compound containing a metal or a metallic ion, which is characterized in that an absorption spectrum curve of the recording organic dye is intersected with an absorption spectrum curve of the organometallic dye compound, and that the organometallic dye compound exhibits a maximum absorption wavelength on a longer wavelength side in relative to a maximum absorption wavelength of the recording organic dye.
