摘要:
The present invention provides a heat sensitive multiple color recording material which produces different color tone by changing applied thermal energy and which has stable developed color image and little color mixture. The heat sensitive color recording material comprises: (a) a substrate, (b) a sublimable dye coloring layer, formed on the substrate (a), and (c) at least one leuco dye color-developing layer, formed on the sublimable dye coloring layer (b), wherein the sublimable dye coloring layer (b) is composed of a sublimable dye layer and a thermoplastic resin layer for fixing the sublimable dye. The leuco dye color-developing layer (c) contains a leuco dye and a developing agent for the leuco dye, and also contains, either within the leuco dye color-developing layer (c) or as an adjacent layer, microcapsules containing a color eraser for erasing the developed color. The color development of the leuco dye color developing layer (c) occurs a temperature lower than that of the sublimable dye, and the developed color of the leuco dye color developing layer (c) is erased by the function of the color eraser emitted from the microcapsules at a temperature which develops color in the sublimable dye coloring layer (b).
