Definitions

  • the present invention relates to a water-erasable ink composition capable of clearly coloring handwriting and erasing the colored handwriting with water.
  • Patent Documents 1 to 15 various water-erasable ink compositions that can erase handwriting with water using a leuco dye and a developer have been provided. That is, after coloring or coating with a developer using an ink containing this lipo-dye and applying water to the handwriting, the developer dissolves in water and dissolves in water. It is an ink composition that erases when the developer is released and the leuco dye returns to its original colorless structure.
  • Examples of the developer include various water-soluble developers, such as water-soluble thiocyanate metal salts such as zinc salts, cobalt salts, and nickel salts, zinc salicylate, gallic acid, and polyoxyalkylene monoallyl monomethyl.
