Multicolor thermosensitive recording medium, method of manufacturing the same, and method of printing using the same

摘要

A multicolor thermosensitive recording medium according to the present invention comprises a first thermosensitive coloring layer (102) which develops by the application of coloring energy, and a second thermosensitive coloring layer (103) which develops in a different color from the first thermosensitive coloring layer by the application of coloring energy. At least one of a region wherein only the monochrome color of the first thermosensitive coloring layer (102) is obtained without coloring the second thermosensitive coloring layer (103), and a region wherein only the monochrome color of the second thermosensitive coloring layer is obtained without coloring the first thermosensitive coloring layer, is provided in a printing region of the multicolor thermosensitive recording medium of the present invention. At least one of the region where only the monochrome color of the first thermosensitive coloring layer is obtained without coloring the second thermosensitive coloring layer, and the region where only the monochrome color of the second thermosensitive coloring layer is obtained without coloring the first thermosensitive coloring layer, can be obtained by preventing color mixing due to the first thermosensitive coloring layer when the second thermosensitive coloring layer is colored in the case where the second thermosensitive coloring layer is laminated over the first thermosensitive coloring layer. This prevention of color mixing may for example be realized by desensitizing or dulling the coloring function of the first thermosensitive coloring layer when it is necessary to develop the color of the second thermosensitive coloring layer.
