  According to the present invention there is provided a compensator capable of diminishing the viewing angle dependency of a liquid crystal display. An optically active polyester containing as a constituent a hydrocarbon unit selected from the group consisting of bulky aromatic units, polycyclic hydrocarbon units and ortho-substituted aromatic units, or a composition containing a liquid crystalline polyester which contains the said hydrocarbon unit as a constituent and also containing an optically active compound, is treated at a temperature higher than the glass transition point of the polyester on an alignment film formed on a light transmitting base and thereafter cooled to a temperature lower than the said glass transition temperature to solidify a cholesteric structure, thereby obtaining a viewing angle compensator for a liquid crystal display.

  In the application and use of absorbent articles, prolonged contact with the material of the sheet, especially in the presence of moisture from exudates or excreta, have an adverse effect on the health of the users skin. It has been found that an improved top sheet material for use in the construction of absorbent articles may be constructed from thermoplastic polymers mixed with certain surface friction reducing agents. These surface friction reducing agents are selected from those used in the manufacture of cosmetic materials and are thus known to have no adverse human etiology. As the top sheet material is formed from thermally extruded films or fibers, it is requisite of the surface friction reducing agents that there is no thermal degradation that adversely effect the contact surface or fluidic transfer to the interior elements of an absorbent article.

  在吸水物品的应用和使用过程中，长时间接触表层材料，特别是在有渗出物或排泄物的湿气存在的情况下，会对使用者的皮肤健康产生不利影响。研究发现，一种用于制造吸收用品的改良表层材料可以由热塑性聚合物与某些表面减摩剂混合制成。这些表面减摩剂选自用于制造化妆品的材料，因此不会对人体产生不良影响。由于表层材料是由热挤压薄膜或纤维形成的，因此表面减摩剂的必要条件是不发生热降解，以免对接触表面或流体向吸收制品内部元件的传递产生不利影响。
