ABSTRACT:
Ink compositions consisting of small unilamellar or multilamellar vesicles formed from surfactants of anionic, cationic, zwitterionic and nonionic molecules having an oil soluble dye, inclusive of a lipid-soluble dye associated therewith are described. The dye to surfactant ratio is preferably from about 1:1 to about 1:10. The compositions are useful in traditional printing techniques such as flexography and rotogravure and in electronic printing systems such as with an ink-jet printer.
