An optical information recording medium is composed of a substrate, a recording dye layer on which information can be recorded by irradiation with a laser beam, and a light-reflecting layer overlaid in order, in which the recording dye layer employs a dye having an organic counter ion (such as a cyanine dye of the formula (I):
[DYE+]nXn- (I)
in which DYE+ is a monovalent cyanine dye cation, n is an integer not less than 2, and Xn- is an organic n-valent anion), and the light-reflecting layer is made of Ag or Ag-containing alloy.
