摘要: An optical information recording medium having a WORM-type recording layer on which information can be recorded by irradiation with a laser light having a wavelength of 440 nm or less, wherein the WORM-type recording layer contains at least one azo-metal complex dye derived from a metal ion (or a metal oxide ion) and an azo dye represented by the following structural formula (I-1) or (I-2). In the structural formulae (I-1) and (I-2), Q represents a carbocyclic group or a heterocyclic group, Q2 and Q3 each represent an atomic group forming a nitrogen-containing heterocycle, and R2 represents a substituent.
