Abstract
Official abstract text for this publication.
An erasable inkjet ink composition includes an ink vehicle including a solvent, and a colorant added to the ink vehicle. The colorant is chosen from an iron-based ionic complex, an iron-based ionic complex in combination with a dye, a non-ascorbic acid based complex, and a dye-blend mono-based colorant.
First claim
Opening claim text (preview).
What is claimed is: 1. An erasable inkjet ink composition, comprising: an ink vehicle including a solvent; and a colorant added to the ink vehicle, the colorant being chosen from an iron-based ionic complex, an iron-based ionic complex in combination with a dye, and a non-ascorbic acid based complex; wherein the erasable ink composition is removable from a medium by degradation of the colorant in response to a chemical reaction between the colorant of the erasable ink composit…
