摘要
This invention relates to polymeric dispersants useful in ink jet ink compositions. The graft polymers comprise monomers having electron rich functional groups, which exhibit favorable interactions with the surface of pigment particles thereby better stabilizing the pigment dispersion within the aqueous ink composition. The graft polymers also comprise hydrophobic monomers having the ability to form hydrogen bonding. The polymers of the present invention provide a dispersant that increases the smear resistance of pigmented inks, especially when used on photo or gelatin paper. The graft polymers also provide excellent chroma for printing. The present invention also relates to aqueous ink compositions which include those polymeric dispersants.
