  Diacetylene time-temperature indicators

  摘要：

  描述了一种改进的记录设备，用于测量物品的综合时间-温度或综合辐射剂量历史，包括基底，其上沉积有至少两个具有共轭C.tbd.C基团的乙炔化合物的不活性形式。该不活性形式能够通过熔融或溶剂重结晶转化为活性形式，后者经历1,4-加成聚合反应，导致不可逆的、渐进的颜色变化。在任何给定时间产生的颜色变化代表物品经历的热退火的综合时间-温度历史或暴露于光敏辐射的综合辐射剂量历史。还描述了一种生产乙炔化合物不活性形式的过程。还描述了由乙炔化合物不活性形式制成的薄膜和纤维。

  An optically readable ambient condition history indicator can have a substrate, an indicator agent on the substrate surface, and a transparent layer overlying the indicator agent. The indicator agent can be capable of changing appearance in response to exposure to an ambient condition and the transparent layer can be subject to exposure to environmental ultraviolet radiation. The indicator can also include a radiation-filtering adhesive layer overlying the indicator agent to secure the transparent layer to the indicator agent, which adhesive layer can include an adhesive and an ultraviolet radiation filter and can contact both the transparent layer and the indicator agent-bearing substrate. The radiation-filtering adhesive layer can protect the indicator agent from ultraviolet radiation transmitted through the transparent layer and provide a simple, robust construction that is easy to manufacture and resists delamination. The adhesive itself is also protected from ultraviolet radiation. A simplified manufacturing method is also disclosed.

  This application relates to a time-temperature indicator based on increased thermal reactivity of a diacetylene upon melt recrystallization and a method of making it. A diacetylene is crystallized into a low thermal reactivity phase from a solvent system and converted into a higher thermal reactivity phase and low sensitivity to UV light by melt re-crystallization.
