<P>PROBLEM TO BE SOLVED: To provide an optical recording medium equipped with a label recording layer, which can exhibit a multi-color display and a decolored display. <P>SOLUTION: This optical recording medium has an optical recording layer 12, on which a label recording layer 14 is formed through an intermediate layer 13, on one principal plane of a supporting board 11. The label recording layer 14 has a structure, in which a plurality of thermosensitive layers are separably laminated. These thermosensitive layers are each so constituted as to respectively include a reversibly thermosensitive color developable composition, which reversibly colors and decolors at least by heat, and a photothermally converting material, which absorbs light having a wavelength region different from one another to generate heat. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
