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.
Claims11
An optical information recording medium comprising at least one recording layer,
- wherein the recording layer includes a recording material comprising a polymer compound to which a one-photon absorption dye is bonded, and
- wherein 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,
- wherein the number of atoms involved in bonding of the one-photon absorption dye to the polymer compound is less than 10.
