Ink-jet inks for ink-jet printing are provided which include a vehicle and a colorant, the colorant associated with a primer core / shell
polymer to form a primer / colorant combination, and the primer / colorant combination, upon printing on a print medium, encapsulated by a durable core / shell
polymer. The primer core / shell
polymer serves to promote adhesion of the durable core / shell polymer to the colorant and to disperse the colorant in the ink and the durable core / shell polymer serves to provide a smear-fast film upon
drying of the ink on a print medium. The primer core / shell polymer comprises a hydrophobic core and a hydrophilic shell comprising a polar component, while the durable core / shell polymer comprises a hydrophobic core comprising a first Tg component, which, when homopolymerized, has a glass trnnsition temperature, Tg, between -150 DEG C. to +25 DEG C. and a second Tg component, which, when homopolymerized, has a
glass transition temperature above +25 DEG C. and a hydrophilic shell selected from the group consisting of neutral shells, cationic shells, and anionic shells.
