A record display medium is provided which can offer a high display contrast and is less likely to cause a lowering of contrast or disappearance of display even in low temperature and high temperature regions. A polymeric material for a liquid crystal/polymer composite film comprising a liquid crystal present in a polymer matrix, a liquid crystal/polymer composite film using the material, and use of the record display medium are also provided. The polymeric material for a liquid crystal/polymer composite film comprising a liquid crystal present in a polymer matrix has a glass transition temperature of 150°C or above and is insoluble in water.
本发明提供了一种记录显示介质,它能提供较高的显示对比度,即使在低温和高温区域也不易导致对比度降低或显示消失。本发明还提供了一种用于液晶/聚合物复合膜的聚合物材料,该材料包括存在于聚合物基质中的液晶、使用该材料的液晶/聚合物复合膜以及该记录显示介质的用途。用于液晶/聚合物复合膜的聚合物材料包含在聚合物基体中的液晶,其
玻璃化转变温度为 150°C 或以上,并且不溶于
水。
