To provide an information recording medium (optical disk) having a dye recording layer including an organic dye having an improved light resistance without impairing recording/reproducing characteristics.

In the information recording medium comprising a recording layer for recording information on a base plate by a laser beam, the recording layer contains an organic dye and a radical anionic salt of a tetracyanoquinodimethane and the like represented by the following general formula (I) [wherein R1, R2, R3 and R4 are independently a hydrogen atom or a substituent (however, R1 and R2, and R3 and R4 may be coupled to form an unsaturated condensed ring), Mk+ is a metal ion, metal complex ion or onium ion, and k is an integer of 1 to 10].
