    • A reversible thermosensitive recording medium comprising at least a reversible thermosensitive recording layer provided on a supporting substrate and, a protective layer provided on the recording layer, wherein the recording layer is arranged so as to develop a first color therein when it is heated to a specific temperature level between a second temperature and a third temperature which is higher than the second temperature and then cooled to a first temperature level between normal temperature and the second temperature which is higher than the normal temperature, while so as to develop a second color therein when it is heated to another temperature level more than a fourth temperature which is higher than the third temperature and then cooled to a particular temperature which is lower than the first temperature, and the protective layer contains at least a lubricant showing the melting point ranging from higher than or equal to the first temperature to lower than or equal to the second temperature and has a surface roughness (Rz) (where Rz represents an average rise on the surface by ten measurements) of 1.2 &mgr;m or more. The recording medium eliminates the gap of air formed between the thermal printing head and the surface, thus heat conductivity is elevated allowing uniform application of thermal energy during the erasing action thereby its erasing property is improved, while the surface smoothness is improved as for as during the heating action at high temperatures, resulting an excellent thermal head matching, and the storage capability therefor is improved.
    • 一种可逆热敏记录介质,其至少包括设置在支撑基底上的可逆热敏记录层,以及设置在记录层上的保护层,其中记录层被布置成当其被加热到特定的 在第二温度和高于第二温度的第三温度之间的温度水平,然后在正常温度和高于常温的第二温度之间冷却到第一温度水平,同时在其中产生第二颜色,当 将其加热到高于第三温度的第四温度的另一温度水平,然后冷却至低于第一温度的特定温度,并且保护层至少含有显示熔点在更高的范围内的润滑剂 超过或等于第一温度低于或等于秒 具有表面粗糙度(Rz)(其中Rz表示通过十次测量的表面上的平均升高)为1.2μm以上。 记录介质消除了在热敏打印头和表面之间形成的空气间隙,从而提高导热性,从而在消除动作期间均匀地施加热能,从而改善其擦除性能,同时表面平滑度如同 在高温下的加热作用,导致优异的热头匹配,并且其储存能力得到改善。
