PURPOSE:To provide an org. optical recording material maintaining stability even after repeated writing and erasing by irradiation with light. CONSTITUTION:A calix [4] arene deriv. having 9-anthryloxyethyl groups substd. at the 25-and 27-positions or the 26-and 28-positions and a sodium salt such as NaClO4 are mixed with a plasticizer-contg. polymer such as PVC to obtain the objective optical respondent compsn. The molar ratio of the sodium salt to the calix [4] arene deriv. is regulated to >=10. |
