Abstract (en)
[origin: WO2013115800A1] The present disclosure is a method for controlling the hysteresis window and improving the color switching properties of reversible thermochromic dye systems. The method adds preferred co-solvents to existing reversible thermochromic dye systems in order to decrease the temperature range between the full color point and the clearing point. The co-solvents also add resistance to ultraviolet radiation.
