Abstract
An ink composition includes water, a co-solvent, a colorant, and a modified polymer or copolymer additive. The modified polymer or copolymer additive is selected from the group consisting of i) a hydrolyzed poly(isobutylene-alt-maleic anhydride), ii) a hydrolyzed poly(maleic anhydride-alt-1-octadecene), and iii) a modified polymer or copolymer. The modified polymer or copolymer includes a repeating unit of a backbone chain, and a long chain pendant group attached to a carbon atom of the repeating unit. In the backbone chain, the long chain pendant group of the repeating unit is separated by fewer than 8 spacer carbon atoms from another long chain pendant group of an adjacent repeating unit.
