ABSTRACT:
A multicolor thermosensitive recording medium having thermosensitive coloring layers which are formed by printing water-dispersion thermosensitive inks or water-dispersion inks on an ink receptive layer using a printing plate. The recording medium comprises an ink receptive layer formed on a surface of a substrate, thermosensitive coloring layers developing different colors, which are integrated with the ink receptive layer by impregnating the ink receptive layer with a water-dispersion thermosensitive ink that is prepared by dispersing in water a pigment component including at least an electron-accepting compound and electron-donating compound. The color density and coloring sensitivity of the thermosensitive coloring layers have been improved by providing over the thermosensitive coloring layers an auxiliary coloring layer containing at least one of an electron-accepting compound and a sensitizer.
