摘要:
The present invention provides an optical information recording medium comprising a substrate having provided thereon a recording layer in which information can be recorded by laser light irradiation, wherein the recording layer contains a dye represented by the following formula (I): Formula (I) wherein Dye represents a dye residue having an absorption as high as 10000 (cm−1·mol−1) or more as a molar extinction coefficient for light having a wavelength of 450 nm to 900 nm; L represents a divalent connecting group or a single bond; UV represents a dye residue having an absorption as high as 10000 (cm−1·mol−1) or more as a molar extinction coefficient for light having a wavelength of 280 nm to 450 nm; and m denotes an integer from 1 to 8.
