Abstract: An optical information recording medium includes at least one recording layer. The recording layer includes a recording material comprising a polymer compound to which a one-photon absorption dye is bonded, and a coupling strength Δ2 between the one-photon absorption dye and the polymer compound in the recording material is higher than a coupling strength estimated to be exerted between the same one-photon absorption dye and the same polymer compound if the one-photon absorption dye is dispersed in the polymer compound in the recording material.
