| titleOfInvention | Reversible thermochromic water-based ink composition and direct liquid writing instrument incorporating the same |
| abstract | PROBLEM TO BE SOLVED: To be used for a writing instrument in which a stirrer that stirs ink is contained in a shaft cylinder that can always form a good handwriting without fading the handwriting obtained by writing after a lapse of time and the color density of the handwriting is also improved. A reversible thermochromic water-based ink composition and a direct liquid writing instrument containing the same are provided. SOLUTION: An ink composition incorporated in a direct liquid writing instrument containing a stirring body for stirring ink in a shaft cylinder, comprising (a) an electron-donating color-forming organic compound, and (b) an electron-accepting property. Compound, (c) Reversible thermochromic microcapsule pigment encapsulating a reversible thermochromic composition comprising a reaction medium that determines the occurrence temperature of the color reaction of both, and adjusting the specific gravity of the reversible thermochromic microcapsule pigment Reversible, consisting of microcapsule particles as the agent and a vehicle containing water and a water-soluble polymer flocculant, and the specific gravity of the vehicle exists between the specific gravity of the reversible thermochromic microcapsule pigment and the specific gravity of the microcapsule particles. Thermochromic water-based ink composition. [Selection figure] None |
