PROBLEM TO BE SOLVED: To provide a dye which can be used for an optical recording medium particularly suitable for recording / reproduction with a short wavelength semiconductor laser. An optical recording medium provided with a recording layer capable of recording and / or reproducing information by a laser on a substrate, wherein the recording layer has a carbostyryl compound represented by the following general formula [I]: Alternatively, an optical recording medium containing a 1,8-naphthyridine compound. (Wherein, X represents a nitrogen atom or C—R 6. R 1 represents an arbitrary substituent. R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are each independently Represents a hydrogen atom or an arbitrary substituent, and two of R 2 to R 8 may be bonded to each other to form a ring.) |
