| titleOfInvention | Discoloring writing instrument |
| abstract | PROBLEM TO BE SOLVED: To provide a color-changing writing instrument that is convenient and capable of quickly erasing the handwriting by a colored photochromic compound without waiting for the handwriting by the colored photochromic compound to disappear over time. . SOLUTION: A color-changing writing instrument 1 comprising a writing instrument body using a photochromic compound such as a spirooxazine derivative or a spiropyran derivative as a coloring material, and a friction body that discolors the photochromic compound from a colored state by frictional heat. Further, a light irradiator is provided, or a friction body is provided on the light irradiator. [Selection] Figure 1 |
