摘要：
The present invention relates to ink-jet ink compositions that comprise macromolecular chromophores having functional groups covalently attached for water solubility. Moreover, the MMCs have polymer chains covalently attached to the pigments by nucleophilic substitution to provide enhanced smearfastness, enhanced print quality, improved bleed control, and improved resistance to water when applied to the media. These inks have good viscosity and surface tension, are more soluble in organic solvents and are, therefore, useful in ink-jet printing, including thermal ink jet printing, piezoelectric ink jet printing, and continuous ink jet printing.
