<P>PROBLEM TO BE SOLVED: To provide an optical information recording medium which is capable of recording and reproducing information in a high recording density mode by emitting a laser beam of a short wavelength of 380 to 500 nm, especially in the neighborhood of a wavelength of 405 nm with a high versatility and has superb recording characteristics. <P>SOLUTION: This optical information recording medium has a recording layer capable of recording information by emitting a laser beam with a wavelength of 380 to 500 nm, formed on a substrate. The recording layer contains a chemical compound represented by formula (I) (wherein R<SP>1</SP>to R<SP>6</SP>are each a substituent group independently; M is a metallic atom; and n is an integer of 1 or more). <P>COPYRIGHT: (C)2003,JPO |
