Liposomal ink compositions with water-insoluble dyes and pigments

摘要

Ink compositions comprising liposome vesicles with water-insoluble dye or pigment contained therein are described. The vesicles may be unilamellar or multilamellar and may be made using standard liposome forming materials such as phospholipids or tocopherol succinate. When the present invention is used with electronic printing systems such as an ink jet printer, the generated images are sharp, fast drying, waterfast, lightfast, and of high optical density.
