Disclosed are polymer having antistatic properties and having a multilayered structure comprising an innermost layer, a second layer, a third layer and an outermost layer; processes for preparing the multilayered polymer; and an antistatic resin composition comprising a thermoplastic resin and the multilayered polymer.
Ink-jet inks for ink-jet printing are provided which include a vehicle and a colorant, the colorant encapsulated by or 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 provide adhesion of the durable core/shell polymer to the colorant 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 low T.sub.g component, which, when homopolymerized, has a glass transition temperature, T.sub.g, below 25.degree. C. and a high T.sub.g component, which, when homopolymerized, has a glass transition temperature above 25.degree. C. and a hydrophilic shell selected from the group consisting of neutral shells, cationic shells, and anionic shells.
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 T.sub.g component, which, when homopolymerized, has a glass trnnsition temperature, T.sub.g, between -150.degree. C. to +25.degree. C. and a second T.sub.g component, which, when homopolymerized, has a glass transition temperature above +25.degree. C. and a hydrophilic shell selected from the group consisting of neutral shells, cationic shells, and anionic shells.
