Time temperature indicators are disclosed which comprise at least one carrier material and one aggregachromic indicator dye and which respond to the combined effects of temperature and time with an easily measurable, time-temperature dependent, irreversible, color change. The invention also discloses to methods to produce such time-temperature indicators and materials therefore. Also, the devices disclose methods for determining the time/temperature history.
本发明揭示了一种时间温度指示器,包括至少一种载体材料和一种聚集色指示
染料,它们对温度和时间的综合影响做出易于测量的时间-温度依赖性的不可逆颜色变化。本发明还揭示了制备这种时间温度指示器和其材料的方法。此外,本发明还揭示了确定时间/温度历史的方法。
