PROBLEM TO BE SOLVED: To prevent the optical deterioration from arising at the time of storage extending to a long period of time by a method wherein an organic coloring matter for recording by a heat mode, and a pyridophenothiazine derivative having an absorption spectrum curve which crosses the absorption spectrum curve of the coloring matter, and also, having a specified maximum absorption wavelength are jointly used. SOLUTION: This optical information recording medium is manufactured by laminating a light interfering layer including a coloring matter layer, on a base plate. In this case, the coloring matter layer contains an organic coloring matter for recording by a heat mode, and also, the light interfering layer is constituted of a pyridophenothiazine derivative which is an organic metallic coloring matter compound containing a metal or a metallic ion. For the pyridophenothiazine derivative, the absorption spectrum curve of the organic coloring matter for recording and the absorption spectrum curve of the organic metallic coloring matter compound cross, and the organic metallic coloring matter compound has a maximum absorption wavelength on a longer wavelength side than the maximum absorption wavelength of the organic coloring matter for recording. For a mixing ratio of the organic coloring matter for recording and the organic metallic compound, it is suitable that 0.1-50 pts.wt. of the latter based on 100 pts.wt. of the former. |
