ABSTRACT:
An improved ink suitable for use in ink-jet printers is provided. The ink includes (a) a vehicle comprising at least one member selected from the group consisting of water and a water-soluble, non-aqueous component, and (b) an anionic dye having cations associated therewith. The ink composition is characterized by further including a macrocyclic polyether associated with the cations, the macrocyclic polyether having binding sites and a cavity size suitable for complexing the cations. The ink composition of the invention evidences reduced crusting, increased fade resistance and, for use in thermal ink-jet printers, reduced kogation.
