| abstract |
A reversible thermosensitive recording material and a recording method capable of forming or erasing a high-contrast, high-sensitivity recorded image many times and obtaining an image excellent in weather resistance are provided. A reversible developer containing a colorless or pale-colored dye precursor, a reversible color developer which causes the dye precursor to reversibly change color upon heating, and a photothermal conversion material having absorption in the near infrared region. On both surfaces of the thermal recording layer, the oxygen permeability at 20 ° C. and 60% RH is 100 ml / m 2 · 24 hr · atm or less, the water vapor permeability at 20 ° C. 60% RH is 100 g / m 2 · 24 hr or less, and at least one of them. Is a reversible thermosensitive recording material provided with a support transparent to visible light and near-infrared light, and a recording method for forming an image on the material using a near-infrared laser.
