FADING INHIBITOR AND OPTICAL INFORMATION RECORDING MEDIUM CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a fading inhibitor excellent in fading inhibition ability and to develop an optical information recording medium capable of improving record regeneration characteristics and preservation stability. SOLUTION: This fading inhibitor has a structure represented by formula (1) (ring A, ring B and ring C each may contain 1-4 substituent groups; R1 and R6 are each a 1-20C substituent group). This optical information recording medium is characterized by comprising the fading inhibitor.
