摘要:
Indicating devices based on the counter balancing effect of one parameter with that of others are disclosed. Color changing and self-reading indicating devices, such as a time indicator having essentially no effect of temperature are developed by this method. In diffusion based time-temperature indicating devices, the effect of temperature is lowered by crosslinking the medium of the device. The devices have net activation energy near zero kcal/mole.
