The present invention provides an optical information recording medium which is capable of high speed recording at, for example, an 8 times or higher speed and is excellent in the stability for storage of recorded material (light fastness). The invention provides an optical information recording medium having light interference layers including a recording layer on a substrate, in which the recording layer comprises an organic dye and contains as a photostabilizer, for example, the compound represented by the following formula 1 wherein at least one of R1 to R8 represents a substituted alkyl group having a terminal cyano group, with the others represent other substituents; Y represents a monovalent or divalent cation; and X<m-> represents a monovalent or divalent anion. <CHEM> |
