Decolorable Ink
  DOI :  10.2352/ISSN.2169-4451.2001.17.1.art00004_1  Published OnlineJanuary 2001

Decolorable ink developed by Toshiba consists of leuco dye, developer, and eraser. The key to fabricating an effective imaging material is to find a balance among these three components. There is equilibrium between colored leuco dye and colorless leuco dye. Because the equilibrium is dominated by colorless state in a solution, an addition of solvent to the ink instantly make it colorless. A similar decoloring process is performed by heating. This decolorable ink technology could be applied to almost all imaging materials.
