Document Type and Number:
WIPO Patent Application WO/2019/123866
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a temperature sensing material having a color density that changes continuously with respect to time, either at or above a prescribed temperature, or at or below a prescribed temperature, and a temperature deviation time estimating system employing the same.
In order to achieve this objective, a temperature sensing material according to the present invention has a structure in which a temperature indicating material which changes color by means of crystallization is dispersed in a dispersion medium, characterized in that the mean particle size of the temperature indicating material is at most equal to a resolution when observed, and the volume fraction of the temperature indicating material in the temperature sensing material is at least equal to 5%.
