ABSTRACT:
In an optical recording medium fitted on a substrate a recording layer containing a light absorbent which absorbs light having a central wave length in the near infrared region, performs thermal conversion of light energy and emits heat energy, and a heat-sensitive recording material, a high density image can be recorded with a small amount of laser irradiation by using a specific water soluble infrared absorbing compound as a light absorbent.
