| abstract | An object of the present invention is to prevent the white plate-like device itself and its surroundings from being stained, and to efficiently and evenly erase written marks over a wide range, and to make maintenance of the white plate-like device convenient. . The writing system includes a writing implement having an ink that can be decolorized from color to colorless by a chemical reaction with water, and a white plate-like device that is written by the writing implement, wherein the ink contains crystal violet lactone. A specific electron-donating color compound and a specific electron-accepting color developing compound containing zinc salicylate are mixed together, and the white plate-like device is a white plate-like body written by the writing implement, and a liquid storage tank. And an applicator for applying the water in the liquid storage tank to the white plate to erase the ink and erase the writing marks. [Selection diagram] Fig. 1 |
