    • A thermal transfer sheet having a base sheet; a thermal transfer dye layer formed on the front side of the base sheet; and a heat resisting and lubricating layer formed on the reverse side of the base sheet. Even if the thermal transfer dye layer contains an indoaniline dye, deterioration in the indoaniline dye can be prevented, the preservability of the thermal transfer can be maintained, fusion of the thermal transfer sheet to a thermal head can be prevented and smooth movement of the thermal transfer sheet is enabled. Thus, sticking which occurs during a printing operation can be prevented. The thermal transfer sheet according to the present invention has a base sheet; a thermal transfer dye layer formed on the right side of the base sheet; and a heat resisting and lubricating layer formed on the reverse side of the base sheet, wherein the thermal transfer dye layer contains an indoaniline dye, and the heat resisting and lubricating layer contains polyoxyethylene sorbitol fatty acid ester and phosphoric ester at a weight ratio of 10:1 to 1:2.
    • 一种具有基片的热转印片; 形成在所述基片的前侧的热转印染色层; 以及形成在基片的背面的耐热润滑层。 即使热转印染料层含有吲哚苯胺染料,也可以防止吲哚苯胺染料的劣化,可以保持热转印的保存性,可以防止热转印片与热敏头的熔合,并使热 转印表已启用。 因此,可以防止在打印操作期间发生的粘附。 根据本发明的热转印片具有基片; 形成在基片的右侧的热转印染料层; 以及形成在基片的背面的耐热润滑层,其中热转印染料层含有吲哚苯胺染料,耐热润滑层含有重量比为10的聚氧乙烯山梨糖醇脂肪酸酯和磷酸酯 1:1:2。

    • The present invention provides a thermal printing sheet which enables to realize a stable low friction coefficient within a heating range by a thermal head and which has a superior preservation stability without giving an adverse affect to dye layers.The thermal printing sheet according to the present invention includes a substrate sheet 1, on one side of which are formed thermal dye layers 2 and on the other side of which is formed a heat resistant slide layer 3. The heat resistant slide layer 3 contains polyoxyalkylene sorbite fatty acid ester which exhibits a superior lubrication characteristic, enabling to obtain a low friction coefficient even under a high temperature. Moreover, the polyoxyalkylene sorbite fatty acid ester is neutral and does no adversely affect the dye layers. The heat resistant slide layer 3, in addition to the polyoxyalkylene sorbite fatty acid ester, may contain polyglycerin fatty acid ester and metallic soap.
    • 本发明提供一种能够通过热敏头在加热范围内实现稳定的低摩擦系数并且具有优异的保存稳定性而不会对染料层产生不利影响的热敏打印片材。 根据本发明的热敏打印片材包括一个基片1,其一侧形成热染料层2,另一侧形成耐热滑动层3.耐热滑动层3含有聚氧化烯 脱脂脂肪酸酯,具有优异的润滑特性,即使在高温下也能获得低摩擦系数。 此外,聚氧化烯山梨糖醇脂肪酸酯是中性的,对染料层没有不利影响。 除了聚氧亚烷基山梨糖醇脂肪酸酯之外,耐热性滑动层3可以含有聚甘油脂肪酸酯和金属皂。
