Reversible thermosensitive recording medium and image forming and erasing method using the recording medium |
摘要 |
A reversible thermosensitive recording medium including a substrate; a reversible thermosensitive recording layer on the substrate, which includes an electron donating coloring compound and an electron accepting compound, wherein the recording layer achieves a colored state when heated at a temperature not lower than an image forming temperature and then cooled at a first cooling speed, and the recording layer in the colored state achieves a non-colored state when heated at a temperature lower than the image forming temperature and not lower than an image erasing temperature or when heated at a temperature not lower than the image forming temperature and then cooled at a second cooling speed relatively slow compared to the first cooling speed; and a crosslinked polymer layer including a crosslinked polymer having an ultraviolet absorbing structure.
