ABSTRACT:
An optical information recording medium having the ability to read or write information by reading or causing changes in the absorption of lasers, comprising a substrate having provided thereon a compound represented by the following general formula, and optionally a quencher: ##STR1## wherein A.sub.1 and A.sub.2 independently represent a hydrogen atom or a substituent; Z represents an atomic group necessary for forming a five-membered heterocycle; R.sub.1 to R.sub.4 independently represent hydrogen atom or a substituent; R.sub.5 represents a substituent or may form a six-membered heterocycle with Z; n represents 0.1 or 2; and X.crclbar. represents an anion.
The optical information recording medium has high sensitivities in recording and regeneration, a high C/N ratio and high resistance to heat, moisture and light, and when a quencher is further contained, durability against repeated irradiation of reading light stability in preservation can be further increased.
