Title:

THERMAL INDICATOR, THERMAL INDICATING COMPOSITION AND THERMAL INDICATING STRUCTURE

Document Type and Number:

WIPO Patent Application WO/2018/176266

Kind Code:

A1

Abstract:

A thermal indicator, a thermal indicating composition (1), as well as two kinds of thermal indicating structures (11) are disclosed. The thermal indicator comprises an organic solid material (2) having a melting point higher than ambient temperature and a dye (3) which contacts the organic solid material (2) and is capable of being dissolved in the organic solid material (2) when the thermal indicator is heated to the melting point of the organic solid material (2). The thermal indicator, the thermal indicating composition (1), as well as these two kinds of thermal indicating structures (1) have simple structures and can be manufactured by a simple process. Furthermore, the existence of the dye (3) in its crystalline state offers significant resistance to UV radiation in outdoor applications.
