Abstract: PROBLEM TO BE SOLVED: To provide a multi-color recording medium capable of repeatedly recording and erasing information, and a recording method. SOLUTION: The reversible multi-color recording medium 10 has a recording layer 14 of the constitution that a plurality of reversible thermosensitive color developing compositions with different developed color tones are sealed in a separated/independent microspace structure, formed on a support substrate 1. In addition, the compositions contain a photothermal conversion material which generates heat by absorbing infrared rays of respectively different wavelength ranges. COPYRIGHT: (C)2004,JPO
