Abstract | [Problem] To provide a thermal recording material which has excellent color development performance in severe environments and is excellent especially in terms of barcode readability. [Solution] A thermal recording material which comprises a support and, disposed thereon, a thermal recording layer containing a colorless or light-colored electron-donating leuco dye and an electron-accepting color developer, characterized in that the thermal recording layer contains a specific sulfone compound and a specific urea-urethane-based compound in a specific proportion as the electron-accepting color developer.
La présente invention vise à fournir un matériau d'enregistrement thermique qui a une excellente performance de développement de couleur dans des environnements difficiles, et qui est particulièrement excellent en termes de capacité de lecture de code à barres. À cet effet, l'invention concerne un matériau d'enregistrement thermique qui comprend un support et, disposée sur celui-ci, une couche d'enregistrement thermique contenant un leuco-colorant de fourniture d'électrons incolore ou de couleur claire et un révélateur de couleur d'acceptation d'électrons, caractérisé en ce que la couche d'enregistrement thermique contient un composé de sulfone spécifique et un composé à base d'urée/uréthane spécifique dans une proportion spécifique en tant que révélateur de couleur d'acceptation d'électrons.
【課題】 本発明は、過酷な環境下における発色性能、特にバーコード読み取り適性に優れる感熱記録体を提供することを目的とする。 【解決手段】 支持体上に、無色ないし淡色の電子供与性ロイコ染料及び電子受容性顕色剤を含有する感熱記録層を設けた感熱記録体において、該感熱記録層が、電子受容性顕色剤として特定のスルホン化合物及び特定のウレアウレタン系化合物を特定比で含有することを特徴とする感熱記録体。 |
