    • The present invention provides a thermal transfer ink ribbon which has good ink transferability and is capable of producing transferred images which are sharp and have high durability. As the main constituent of a binding material of thermally fusible resin, fine particles of low slipperiness which are not softened at a temperature at which the binding material is softened are contained in an ink layer 13 when the ink layer 13 is deposited to produce a thermal transfer ink ribbon 1. Since the thermally fusible resin is used, the durability of transferred images is high. Because the fine particles are contained, the ink layer can be separated sharply from the thermal transfer ink ribbon 1. As the fine particles are of low slipperiness, no slippage occurs between the thermal transfer ink ribbon 1 and a transfer medium. The fine particles of low slipperiness have an average diameter ranging from 0.3 .mu.m to 3.0 .mu.m, and are made of one or more of a condensation resin of benzoguanamine and formaldehyde, a condensation resin of melamine and formaldehyde, a condensation resin of benzoguanamine, melamine, and formaldehyde, and tetrafluoroethylene. The fine particles of low slipperiness may be contained in the ink layer 13 in an amount exceeding 10% by weight and less than 60% by weight, or preferably in an amount ranging from 20% by weight to 50% by weight.
    • 本发明提供一种热转印墨带,其具有良好的墨转移性,并且能够产生锋利且具有高耐久性的转印图像。 作为热熔性树脂的粘合材料的主要成分,当油墨层13沉积时,在粘合材料被软化的温度下不软化的低滑性的细颗粒被包含在油墨层13中,以产生热 转印墨带1.由于使用了热熔树脂,转印图像的耐久性高。 由于含有微粒,所以油墨层可以与热转印色带1急剧分离。由于微粒的滑动性低,在热转印色带1和转印介质之间不会发生滑动。 低滑性细颗粒的平均直径为0.3μm至3.0μm,由苯并胍胺和甲醛的缩合树脂,三聚氰胺和甲醛的缩合树脂,苯并胍胺的缩合树脂, 三聚氰胺和甲醛,以及四氟乙烯。 低透光性的微粒子可以以超过10重量%且小于60重量%的量存在于油墨层13中,优选为20重量%〜50重量%的量。
