    摘要: A reversible multicolor thermal recording medium capable of recording and erasing repeatedly high-contrast clear images free of color fogging without causing color deterioration and a method for recording on the recording medium. The reversible multicolor recording medium includes recording layers numbered from the first to the nth, which are formed on a supporting substrate separately and independently in sequential order, the recording layers each containing a reversible thermal color developing composition differing from one another in the hue of the developed color and further containing a light-heat converting composition which generates heat upon absorption of near infrared rays with a wavelength in different ranges, and the recording layers having respectively the absorption peak wavelengths λ max 1, λ max 2, . . . , λ max n, in the near infrared region such that 1500 nm>λ max 1>λ max 2> . . . >λ max n>750 nm.
