| titleOfInvention | Aqueous decolorizable ink composition for writing instruments |
| abstract | The present invention has been made in order to solve the problems in conventional water-based decoloring ink compositions for writing instruments, and is a rate of decoloring or discoloring when the handwriting is traced with an erasing ink composition. An object of the present invention is to provide a water-repellent ink composition for a writing instrument that is fast and has excellent workability. According to the present invention, it contains water, a basic dye that can be decolored by a reducing agent, and a decoloring aid consisting of at least one selected from di (long-chain alkyl) di (lower alkyl) ammonium halides. A water-based decolorizable ink composition for writing instruments is provided. As the reducing agent, sodium sulfite or potassium sulfite is particularly preferably used. |
