Optical information recording medium, information recording method, and dye compound

摘要

An optical information recording medium whose recording layer includes a phthalocyanine derivative having a substituent of the following formula (I): (in the formula (I), R¹, R² and R³ each independently represent a substituent other than a hydrogen atom). A dye compound represented by the following formula (II): (in the formula (II), M represents a metal or a metal oxide each of which may have a ligand. R⁴, R⁵ and R⁶ each independently represent a substituent other than a hydrogen atom, and n is an integer of from 1 to 8).
