Abstract
This invention relates to indicating devices, such as time-temperature indicators based on lateral diffusion of a vapor of a solid and/or liquid mobile phase (e.g., a sublimeable dye or an activator) through a non-porous stationary phase, such as a thin layer of a polymeric material. The lateral diffusion of the mobile phase creates a noticeable boundary in the stationary phase whose movement depends upon processes, such as time and temperature.
