An optical recording medium capable of recording information by irradiation of light is provided with a substrate on which there is formed a recording layer which contains an organic dye comprising an organic dye matrix, and at least one C7 or greater branched organic group bonded by a single bond to the organic dye matrix and branching at a prescribed position into a C5 or greater organic group and a functional group other than a hydrogen atom, and/or at least two C5 or greater organic groups. This adequately prevents gas generation due to thermal decomposition of the organic dye, and the accompanying pressure fluctuation, even with the increasing temperature produced by irradiation with a high power laser, so that it becomes possible to form precise recording pits while achieving a high level of sensitivity and high speed responsiveness even under high-temperature conditions.
