Principle of color change
The reverse thermochromic dye changes its color by the heat-induced chemical structure change. Since the dye is very sensitive to an external environment, it is made as a microcapsule-type product for protection, enhancing its repetitive durability.
when heat is apllied to reverse thermochromic microcapsule, the substance structure inside the microcapsule changes and the color appears. When cooled down, the microcapsule recovers its original structure, and the color disappears.
Reverse thermochromic one from colorless to colored reversibly.
