发明名称 Method for erasing image on thermoreversible recording medium
摘要 <p>A method for erasing an image including irradiating an image formed on a thermoreversible recording medium with a laser light having a wavelength of 700 nm to 1,500 nm so as to erase the image, wherein an energy density of the laser light is in a range of the energy density which can erase the image and more than a center value of the range, wherein the thermoreversible recording medium includes a support, and a thermoreversible recording layer on the support, and wherein the thermoreversible recording layer contains a leuco dye serving as an electron-donating color-forming compound and a reversible developer serving as an electron-accepting compound, in which color tone reversibly changes by heat, and at least one of the thermoreversible recording layer and a layer adjacent to the thermoreversible recording layer contains a photothermal conversion material, which absorbs the light and converts the light into heat.</p>
