    摘要: The present invention relates to a stretchable blend comprising a stretchable liquid crystal polymer and a thermoplastic. These stretchable blends can be stretched at the same temperature range as many conventional thermoplastics. During a post orientation process, such as fiber or film stretching, the stretchable liquid crystal polymer can stretch and deform along with the thermoplastic matrix maintaining adhesion between the liquid crystal polymer domains and the thermoplastic matrix thereby improving the physical properties of the oriented article.

    摘要: An objective of the present invention is to provide a liquid crystal composition whose orientation undergoes a large change upon irradiation with light, and which also has a large birefringence nulln. The liquid crystal composition contains an aromatic acetylene compound and a chiral compound that undergoes a structural change upon photoreaction, and has such properties that, upon irradiation with light, its helical pitch undergoes a large change in accordance with the level of the light intensity, and that has a large birefringence nulln. Therefore, the present invention makes it possible to provide a reflection type color filter which utilizes the liquid crystal composition, and which provides a lighter display with high reflectance. Moreover, the present invention also provides an optical film that can be formed as a thinner film using the liquid crystal composition.
