发明名称 Ink-jet compositions containing modified macromolecular chromophores with covalently attached polymers
摘要 <p>The present invention relates to ink-jet ink compositions that comprise modified pigment particles (macromolecular chromophores) having functional groups covalently attached for water solubility and polymer chains covalently attached to the pigments. These pigmented inks have enhanced smearfastness, enhanced print quality, improved bleed control, and improved resistance to water when applied to the media. Moreover, these inks have good viscosity and surface tension. These inks are useful in ink-jet printing, including thermal ink jet printing, piezoelectric ink jet printing, and continuous ink jet printing.</p>
