Abstract
(EN) Provided is a thermal transfer sheet which exhibits good printing performance and still provides a printed material that has excellent resistance to boiling. A thermal transfer sheet which is obtained by sequentially providing one surface of a base with at least a transferable protective layer and a transferable coloring layer in this order and by providing the other surface of the base with a back surface layer. The transferable protective layer contains, as a main component, a cyclic olefin polymer having a glass transition temperature of 100°C or more and additionally contains a resin that is incompatible with the cyclic olefin polymer. The transferable coloring layer contains a coloring agent and a phenolic resin having a softening point of 100°C or more.
(FR) L'invention concerne une feuille de transfert thermique qui présente une bonne performance d'impression et fournit toujours un matériau imprimé qui présente une excellente résistance à l'ébullition. Une feuille de transfert thermique qui est obtenue par agencement de façon séquentielle d'une surface d'une base avec au moins une couche de protection transférable et d'une couche de coloration transférable dans cet ordre et par agencement de l'autre surface de la base avec une couche superficielle arrière. La couche de protection transférable contient, comme composant principal, un polymère d'oléfine cyclique qui présente une température de transition vitreuse égale ou supérieure à 100 °C et, de plus, contient une résine qui est incompatible avec le polymère d'oléfine cyclique. La couche de coloration transférable contient un agent colorant et une résine phénolique qui présente un point de ramollissement égal ou supérieur à 100 °C.
(JA)  印字性が良好でありながら、印字物の耐ボイル性に優れた熱転写シートを提供する。 基材の一方の面に少なくとも転写性保護層、転写性着色層がこの順に設けられ、該基材の他方の面に背面層が設けられてなり、前記転写性保護層は、ガラス転移温度が100℃以上の環状オレフィン系重合体を主成分として含み、更に当該環状オレフィン系重合体に対する非相溶性樹脂を含み、前記転写性着色層は、着色剤と、軟化点100℃以上のフェノール樹脂とを含む、熱転写シート。
