| titleOfInvention | Ink composition for reversibly thermochromic stamps and stamp |
| abstract | [Problem] To provide: an ink composition for reversibly thermochromic stamps, whereby a seal image does not decolor even when left in a high-temperature environment; and a stamp comprising same. [Solution] An ink composition for reversibly thermochromic stamps, containing water, a thickener, and a reversibly thermochromic microcapsule pigment containing therein a reversibly thermochromic composition comprising: a component (A) being an electron-donating color-developing organic compound; a component (B) being an electron-accepting compound; and a component (C) being a reaction medium that reversibly causes an electron exchange reaction between components (A and B) in a specified temperature range. The reversibly thermochromic composition exhibits a first color phase at a complete coloring temperature, exhibits a second color phase at a complete decoloring temperature higher than the complete coloring temperature, is capable of mutually changing coloring by changing the temperature, exhibits hysteresis characteristics whereby one of the color phases is held in a temperature range between the coloring start temperature and the decoloring start temperature, has a coloring start temperature of no more than 15°C, and has a complete decoloring temperature of at least 80°C. |
