PROBLEM TO BE SOLVED: To provide a pigment-based ink composition useful in an inkjet ink application. A composition comprising a liquid vehicle and a polymer encapsulating a pigment. The polymer comprises a first monomer selected from ethylenically unsaturated hydrophobic monomers and a second monomer selected from maleic anhydride, maleic acid and salts, esters, imides and amides thereof. A composition that is cross-linked via a carboxylate group of the monomer of. The first monomer is present in the polymer in an amount in the range of 40-90 mol% relative to the polymer and the second monomer in an amount in the range of 10-60 mol% relative to the polymer, 90- A composition having an acid value in the range of 325.
