| titleOfInvention | Invertable color seal ink composition and seal |
| abstract | An object of the present invention is to provide a reversible thermochromic seal ink composition which does not decolorize even when placed in a high temperature environment, and a stamp having the composition built therein. The solution of the present invention is a reversible thermochromic seal ink composition comprising a reversible thermochromic microcapsule pigment, water and a tackifier, and the reversible thermochromic microcapsule pigment is contained therein. a reversible thermochromic composition comprising: an electron-donating color-developing organic compound of the component (A); an electron-accepting compound of the component (B); and a reaction medium of the component (C); It can cause the electron transfer reaction of the component (A) and the component (B) to reversibly occur in a specific temperature region; wherein the reversible thermochromic composition exhibits a first hue at a temperature t1, and is higher than a temperature t1. At the temperature t4, the second hue is present, and the color change can be alternately converted between the first hue and the second hue by the temperature change; the reversible thermochromic composition having the first hue at the temperature t1 is subjected to When the temperature is raised, the discoloration starts at the temperature t3, and the second hue is completely present in the temperature region above the temperature t4 above the temperature t3; the reversible thermochromic composition of the second hue has been exhibited at the aforementioned temperature t4. Object When cooling, the discoloration starts at a temperature t2, and the first hue is completely present in a temperature region below the aforementioned temperature t1 below the temperature t2; the reversible thermochromic composition is at the aforementioned temperature t2 and the aforementioned temperature t3 The hysteresis characteristic of maintaining the first hue or the second hue is displayed in the temperature region between the two, and the temperature t2 is a temperature of 15 ° C or lower, and the temperature t4 is a temperature of 80 ° C or higher. |
