Solubility additive for ink compositions
An additive for improving the solubility of dyes in a dye composition is disclosed. The additive is a zwitterion that has a polarity greater than the polarity of a solvent in which the dye is dispersed or solubilized. In one embodiment, the additive comprises an amino acid or a derivative of an amin...

| description | An additive for improving the solubility of dyes in a dye composition is disclosed. The additive is a zwitterion that has a polarity greater than the polarity of a solvent in which the dye is dispersed or solubilized. In one embodiment, the additive comprises an amino acid or a derivative of an amino acid. Dye compositions formulated according to the present invention are particularly well suited for use in ink-jet printers. |
