(wherein substituents X and Y each independently represent an aryl group or a heteroaryl group, rings A and B each independently represent an oxazole ring or a thiazole ring, and Q1 and Q2 each independently represent a hydrogen atom, a halogen atom or an alkyl group, with a proviso that, aryl group(s) or heteroaryl group(s) represented by the substituents X and Y each independently may be substituted by a halogen atom, a hydroxyl group, a cyano group, an amino group or a substituted or unsubstituted alkyl, aralkyl, aryl, alkenyl, alkoxy, aralkyloxy, aryloxy, alkenyloxy, alkylthio, aralkylthio, arylthio, alkenylthio, mono-substituted amino, di-substituted amino, acyl, alkoxycarbonyl, aralkyloxycarbonyl, aryloxycarbonyl, alkenyloxycarbonyl, mono-substituted aminocarbonyl, di-substituted aminocarbonyl, acyloxy or heterocyclic ring group).
一种光学记录介质,在基底上具有作为记录层的有机染料层,其中记录层中含有至少一种由通式(1)表示的苯并异噁唑基化合物:
(其中取代基 X 和 Y 各自独立地代表芳基或杂芳基,环 A 和 B 各自独立地代表噁唑环或噻唑环,以及 Q1 和 Q2 各自独立地代表氢原子、卤素原子或烷基,但条件是,取代基 X 和 Y 各自独立地代表的芳基或杂芳基可被卤素原子取代、羟基、氰基、氨基或取代或未取代的烷基、烷基、芳基、烯基、烷氧基、烷氧基、芳氧基、烯氧基、烷硫基、烷硫基、芳硫基、芳硫基、烯硫基、单取代氨基、二取代氨基、酰基、烷氧基羰基、烷氧基羰基、芳氧基羰基、芳氧基羰基、烯氧基羰基、单取代氨基羰基、二取代氨基羰基、酰氧基或杂环基)。
