An optical recording medium having an organic dye layer as a recording layer on a substrate, wherein the recording layer contains a benzobisazole compound represented by at least one general formula (1) in the recording layer.n n n n n n n n [Wherein, substituents X and Y each independently represent an aryl group and a heteroaryl group, ring A and B each independently represent an oxazole ring or thiazole ring, and Q 1 and Q 2 each independently represent a hydrogen atom, Halogen atom and an alkyl group are shown. However, with respect to the aryl group or heteroaryl group represented by the substituents X and Y, each independently, a halogen atom, a hydroxyl group, a cyano group, an amino group, a substituted or unsubstituted alkyl group, an aralkyl group, an aryl group, an alkenyl group, alkoxy Group, aralkyloxy group, aryloxy group, alkenyloxy group, alkyl thio group, aralkyl thio group, aryl thio group, alkenyl thio group, mono-substituted amino group, di-substituted amino group, acyl group, alkoxycarbonyl group, aralkyl It may be substituted by an oxycarbonyl group, an aryloxycarbonyl group, an alkenyloxycarbonyl group, a mono-substituted aminocarbonyl group, a di-substituted aminocarbonyl group, an acyl oxy group or a heterocyclic group.] |
