An optical recording medium having an organic dyenlayer as a recording layer on a substrate, wherein atnleast one benzobisazole-based compound represented by angeneral formula (1) is contained in the recording layer:n n(wherein substituents X and Y each independentlynrepresent an aryl group or a heteroaryl group, rings Anand B each independently represent an oxazole ring or anthiazole ring, and Q 1 and Q 2 each independently representna hydrogen atom, a halogen atom or an alkyl group, with anproviso that, aryl group(s) or heteroaryl group(s)nrepresented by the substituents X and Y eachnindependently may be substituted by a halogen atom, anhydroxyl group, a cyano group, an amino group or ansubstituted or unsubstituted alkyl, aralkyl, aryl,nalkenyl, alkoxy, aralkyloxy, aryloxy, alkenyloxy,nalkylthio, aralkylthio, arylthio, alkenylthio, mono-substitutednamino, di-substituted amino, acyl,nalkoxycarbonyl, aralkyloxycarbonyl, aryloxycarbonyl,nalkenyloxycarbonyl, mono-substituted aminocarbonyl, di-substituted naminocarbonyl, acyloxy or heterocyclic ringngroup). |
