PROBLEM TO BE SOLVED: To improve the heat and chemical stability of a coloring film by adding a specific ratio of a metallic complex compound and aromatic amine compound shown in organic coloring matter with a specific formula as a singlet enzyme deactivation agent, and specifying a weight ratio with respect to a metallic complex compound of an aromatic amine compound. SOLUTION: A recording medium is formed by laminating a recording layer and metallic reflection layer on a light permeable substrate. In this instance, as a recording layer, a metallic complex compound shown by formula I and an aromatic amine compound shown by formula II are permitted to be in the range from 10:1 to 1:10 in a weight ratio relative to a metallic complex compound of an aromatic amine compound, and a composed organic compound film is used to an organic coloring matter film consisting mainly of an organic matter having absorption to a light wave length of 500-700 nm at a rate of 1.5 pts.wt. to 30 pts.wt. respectively. In the formula, R1, R2 are electron absorptive substitutional groups, M is tervalent acidifiable transition metal or noble metal, R3-R10 are hydrogen and an alkyl group, and X is an anion such as Br or ClO4. |
