    • The present invention provides a temperature-indicating sheet which, when exposed to temperatures higher than the prescribed temperature in temperature-control for the common low-temperature preserved goods, changes in color according to the exposure temperature and time. This object is attained by arranging one component which melts at the prescribed temperature and a substance which irreversibly changes in color in contact with said component through a membrane permeable to the component. The sheet of the present invention comprises a component which melts at the prescribed temperature, a substance which changes in color in contact with the component and a membrane permeable to the molten component, said component being included in microcapsules which can be broken by outer pressure at a temperature used, and in which the component and the substance are arranged at the opposite sides with respect to the membrane.

    • Polydiacetylene gel compositions, comprised of a polydiacetylene and a gel-forming liquid therefor, are described which undergo a change in color and in physical state to a solution when heated to a predetermined temperature. The gel compositions exhibit hysteresis temperature characteristics which allow the original color change to be maintained and recorded until the solution is cooled below the predetermined temperature. Thus, the gel compositions are useful in temperature-indicating devices for reversibly monitoring a wide range of temperatures. A novel class of polydiacetylene compounds is also described, useful in forming the gel compositions, formed from monomeric diacetylenediol bis(alkoxycarbonylmethylurethanes).
    • 描述了由聚二乙炔及其形成凝胶的液体组成的聚二乙炔凝胶组合物,其在加热到预定温度时经历颜色变化和物理状态下的溶液。 凝胶组合物显示滞后温度特性,其允许维持和记录原始的颜色变化,直到溶液冷却到预定温度以下。 因此,凝胶组合物可用于温度指示装置,用于可逆地监测宽范围的温度。 还描述了一类新型的聚二乙炔化合物,可用于形成由单体二乙炔二醇双(烷氧基羰基甲基氨基甲酸酯)形成的凝胶组合物。
