Abstract
The present invention relates to anisotropic colorants and ink-jet ink compositions that include the anisotropic colorants. These anisotropic colorants are highly stable and can be designed to provide enhanced chroma, gloss, gloss uniformity, smearfastness, print quality, drytime, and improved resistance to water when applied to a media. Moreover, inks formulated with these new colorants are useful in ink-jet printing, including thermal ink jet printing, piezoelectric ink jet printing, and continuous ink jet printing.
