摘要:
An optical recording medium having a recording layer which contains at least one compound selected from the group consisting of mono-, di-, and triazaporphyrin compounds optionally in the form of a metal complex; or an optical recording medium comprising a substrate and formed thereon at least a recording layer containing an organic dye as a main component, characterized in that the organic dye has a first maximum value of absorption at a wavelength λ1 of 400 nm or less in the absorption spectrum and has a second maximum value of absorption at a longer-wavelength side than the λ1, and a wavelength band wherein the refractive index (n) and the absorption coefficient (k) of the above organic dye satisfy n ≥ 1.90 and 0.03 ≤ k ≤ 0.30.
