Reversible multicolor recording medium, and recording method using the same

摘要

A reversible multicolor recording medium includes a supporting substrate, and recording layers which have, respectively, a plurality of reversible thermal coloring compositions having different colors. The recording layers are separated from and stacked on one another on the supporting substrate. The reversible thermal coloring compositions respectively include light-to-heat transforming materials which respectively absorb infrared rays having different wavelength ranges to generate heat.
