• TEMPERATURE SUPERVISION AND DISPLAY UNIT

  A temperature supervision and display unit is provided with micro-capsules, each containing a hydrophobic organic material of any melting point, and a methine coloring matter and an oxidizing material which are retained on a carrier. More specifically, a unit which is used to supervise temperature is provided with a methine coloring matter which irreversibly changes color and an oxidizing material, combined with micro-capsules containing a hydrophobic organic compound of a predetermined melting point, and these are retained on a carrier. It is preferable to form cracks in the micro-capsules of the unit below the desired supervision temperature, and then place the unit with the article whose temperature is to be controlled when the article is being stored or transported. Thus, when the temperature of the article exceeds the desired supervision temperature, the nonvolatile organic compound emerging from the bust micro-capsules melts and diffuses to bring the methine coloring matter and oxidizing compound which are adjacent to each other into contact with each other, causing an irreversible color change in the coloring matter. This color change makes it possible to detect an abnormality in temperature conditions.

  温度监控和显示装置配有微胶囊，每个微胶囊都含有任意熔点的疏水性有机材料，以及保留在载体上的甲烷着色剂和氧化剂。更具体地说，一个用于监控温度的单元配有不可逆变色的甲烷着色剂和氧化材料，以及含有预定熔点的疏水性有机化合物的微胶囊，这些都保留在载体上。最好是在低于所需的监控温度时，在装置的微胶囊中形成裂缝，然后在储存或运输物品时，将装置与需要控制温度的物品放在一起。这样，当物品的温度超过所需的监控温度时，从破裂的微胶囊中出现的不挥发性有机化合物就会熔化并扩散，使相邻的甲烷着色物质和氧化化合物相互接触，从而导致着色物质发生不可逆的颜色变化。通过这种颜色变化可以检测到温度条件的异常。
