<P>PROBLEM TO BE SOLVED: To provide a reversible multi-color thermosensitive recording medium which shows clear color developing/decolorizing action, sharp color contrast and the capability of repeating a cycle of recording/erasing a color image, and a recording method using this recording medium. <P>SOLUTION: In the reversible multi-color recording medium of such constitution that recording layers 11 to 13 are laminate formed in the planar direction of a supporting substrate 1, the recording layers 11 to 13 contain a photothermal conversion material which generates heat by absorbing infrared rays of respectively different wavelength ranges; a coloring compound; color developing/color subtracting agents; and a sensitizer. The recording sensitivity is enhanced by specifying a chemical structure relative to the color developing/color subtracting agents and the sensitizer and realizing excellent color developing/decolorizing properties, sharp color contrast and high image definition. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
