Irreversible thermochromic ink compositions |
| abstract |
Disclosed herein are irreversible thermochromic ink compositions including a volatile color activator and a color change dye capable of becoming substantially colorless upon evaporation of the volatile color activator. The volatile color activator and the color change dye can be, optionally, encapsulated. Written marks made with the thermochromic ink compositions can be subjected to a force directing component, which can include generating heat and/or friction, to evaporate the volatile color activator, thereby causing the color change dye to become substantially colorless. |
