Reversible thermosensitive recording medium, label, and image forming and erasing method using the same |
摘要 |
<p>A reversible thermosensitive recording medium comprising an concealing layer provided between a reversible thermosensitive recording layer which is reversibly changed in its color by heat and a photo-thermal conversion layer which absorbs light with generating heat, characterized by the concealing layer has an optical characteristic that the ratio of a light absorptivity of light having 555 nm wavelength, in comparison with a light absorptivity of laser light wavelength, is 80% or less. This reversible thermosensitive recording medium has a concealing layer to conceal the color of the photo-thermal conversion layer, thereby the visibility and the contrast of the obtained images are significantly improved, further more, durability in repeated used is also significantly improved. <IMAGE></p> |
