Information recording medium and recording method

摘要

An optical information recording medium comprising a substrate having thereon a recording layer capable of information recording by laser irradiation, wherein said recording layer contains a dye compound represented by the following formula (I), (II) or (III): R<11>R<12>N<+>=L<11>-L<12>=L<13>-NHR<13> . (1/m) (X<1>) R<21>R<22>N-L<21>=L<22>-L<23>=NR<23> R<31>R<32>N<+>=L<31>-L<32>=L<33>-NR<33>R<34> . (1/n) (X<3>) The meanings of the symbols are defined and explained in the specification. Also disclosed is a method for recording information using the optical information recording medium.
