Title
(EN) REVERSIBLE RECORDING MEDIUM AND EXTERIOR MEMBER
(FR) SUPPORT D'IMPRESSION RÉVERSIBLE ET ÉLÉMENT EXTÉRIEUR
(JA) 可逆性記録媒体および外装部材
Abstract
(EN)
The reversible recording medium according to one embodiment comprises: a recording layer containing an electron-donating coloring compound, an electron-accepting color-developing/color-reducing agent, a photothermal conversion agent, and a polymer material; and a UV absorbing layer disposed on the recording layer. The polymer material is an organic material that has a solubility of 20 to 80 wt% at 25°C or lower and that contains 0.5 wt% or less of intramolecular chlorine atoms, fluorine atoms, and sulfur atoms.
(FR)
L’invention concerne, selon un mode de réalisation, un support d'impression réversible comprenant : une couche d'impression contenant un composé colorant donneur d'électrons, un agent de développement de couleur/d’atténuation de couleur accepteur d’électrons, un agent de conversion photothermique et un matériau polymère ; et une couche absorbant les UV disposée sur la couche d'impression. Le matériau polymère est un matériau organique présentant une solubilité de 20 à 80 % en poids à 25 °C ou moins et qui contient 0,5 % en poids ou moins d'atomes de chlore, d’atomes de fluor et d’atomes de soufre intramoléculaires.
