  The present invention is directed to an optical information recording medium for carrying out recording, readout and erasing with laser beams which comprises a support having carried thereon at least one of the compounds represented by the following general formulae (I), (II), (III) and (IV): ##STR1## wherein X and X' each represents an atomic group necessary for forming a carbon ring or an atomic group necessary for forming a specific heterocyclic ring; L.sup.1 mainly represents a methine group, or a group formed by linking 3 or 5 methine groups in turn to form conjugated double bonds; and Q and Q' each represents an atomic group whereby a conjugated double bond chain is completed; ##STR2## wherein L.sup.1 and Q are as defined in general formula (I); Z represents an atomic group necessary for forming a carbon ring or heterocyclic ring; R.sup.1 to R.sup.3 and E represent various substituents; and M represents an ion, etc.; ##STR3## in the above general formulae (III) and (IV), A represents an atomic group necessary for forming a pyridine, pyrimidine, pyrazine or triazine ring; and L.sup.2 represents a methine group, or a group formed by linking 3 or 5 methine groups in turn to form conjugated double bonds. Optical information recording media of the invention each have a high C/N and thus adequate recording characteristics, and have a high stability with respect to long-term preservation or long-time reading. These effects may further be enhanced by using a singlet oxygen quencher.

  本发明涉及一种光学信息记录介质，用于利用激光束进行记录、读出和擦除，其包括一个支撑体，在其上搭载至少一种由下列通式（I）、（II）、（III）和（IV）所表示的化合物：##STR1## 其中，X和X'各代表形成碳环所必需的原子基团或形成特定杂环所必需的原子基团；L1主要表示一个亚甲基基团，或通过连接3个或5个亚甲基基团依次形成共轭双键的基团；Q和Q'各代表完成共轭双键链的原子基团；##STR2## 其中，L1和Q的定义如通式（I）中所述；Z代表形成碳环或杂环所必需的原子基团；R1至R3和E代表各种取代基；M代表离子等；##STR3## 在上述通式（III）和（IV）中，A代表形成吡啶、嘧啶、吡嗪或三嗪环所必需的原子基团；L2表示一个亚甲基基团，或通过连接3个或5个亚甲基基团依次形成共轭双键的基团。本发明的光学信息记录介质具有高C / N，因此具有足够的记录特性，并且具有高稳定性，可长期保存或长时间读取。这些效果可以通过使用单线态氧猝灭剂进一步增强。
