ABSTRACT:
Disclosed is to provide with an optical recording medium of a write-once type in which an excellent recording characteristic can be obtained over low speed recording to high speed recording.In an optical recording medium having a recording layer that contains an organic dye, the recording layer is configured to have at least an organic dye expressed by a general formula shown in the following chemical formula 1 (in this formula, R1 represents an alkyl group of carbon number 1 through 4, R2 and R3 represent respectively an alkyl group of carbon number 1 through 4 and a benzyl group or group forming three to six-member ring by coupling, each of Y1 and Y2 represents independently an organic group, and X represents ClO4, FB4, PF6, and SbF6) and an organic dye expressed by a general formula shown in the following chemical formula 2 (in this formula, R1 and R4 represent an alkyl group of carbon number 1 through 4, R2 and R3 represent respectively an alkyl group of carbon number 1 through 4 and a benzyl group or group forming three to six-member ring by coupling, each of Y1 and Y2 represents independently an organic group, and X represents ClO4, FB4, PF6, and SbF6).
