    • Thermal transfer recording is improved by a recording method involving providing a thermal transfer material having a support and an ink layer disposed thereon and which in turn includes a binder and a colorant. The binder includes 45-70 wt. % of an ethylene-vinyl acetate copolymer, 25-50 wt. % of a wax, and 7-12 wt. % of a tackifier based on a total weight of the binder. The ink layer has a breakdown strength of 30-80 kg/cm.sup.2 at 25.degree. C. The method also involves contacting an ink layer side of the thermal transfer material with a recording medium, supplying a pattern of energy from a recording head to the thermal transfer material, and separating the thermal transfer material from the recording medium to leave a transferred image on the recording medium. The thermal transfer material moves in a unit period of time by a first distance relative to the recording head which is smaller than a second distance through which the recording medium moves relative to the recording head in the same unit period of time.
    • 通过提供具有支撑体的热转印材料和设置在其上的油墨层并且还包括粘合剂和着色剂的热转印材料的记录方法来改进热转印记录。 粘合剂包括45-70wt。 %的乙烯 - 乙酸乙烯酯共聚物,25-50wt。 %的蜡,和7-12wt。 基于粘合剂的总重量的增粘剂的%。 油墨层在25℃下的击穿强度为30-80kg / cm2。该方法还包括使热转印材料的油墨层与记录介质接触,将记录头的能量图案提供给热 转印材料,并将热转印材料与记录介质分离,以将转印图像留在记录介质上。 热转印材料在单位时间内相对于记录头移动第一距离,该距离小于记录介质在相同的单位时间内相对于记录头移动的第二距离。
