Eradicable inks |
| abstract |
An eradicable ink contains an essentially non-aqueous solvent and a colorant, dissolved in the solvent, that changes color if contacted with a sulfite or an amine. Moreover, a water soluble colorant containing a counterion hydrophilic can be converted into a water insoluble colorant by substituting a hydrophobic counterion for the hydrophilic counterion. |
