The present invention is drawn to a method of preparing anti-oxidant-modified latex particulates, ink-jet inks, and coating compositions. The present invention is also drawn to related latexes and ink-jet inks. The method can include steps of generating an emulsion with a hydrophilic continuous phase and a hydrophobic discontinuous phase, wherein the hydrophobic discontinuous phase includes monomers for polymerization, at least one monomer being modified by an anti-oxidant moiety; and polymerizing the monomers in the hydrophobic discontinuous phase using a biocatalytic polymerization process.
