Abstract
An inkjet ink including a polymer-attached pigment formulated to exhibit a compact configuration and an elongated configuration, which provides the polymer-attached pigment with a variable particle size. The polymer-attached pigment may include a pigment having at least one polymer attached to its surface. The at least one polymer may be formed from a hydrophobic segment and a hydrophilic segment, where the hydrophilic segment is soluble in an aqueous environment and the hydrophobic segment is insoluble in the aqueous environment. The polymer-attached pigment may be dispersed in an ink vehicle to provide a low viscosity inkjet ink. The inkjet ink may optionally include at least one binder formed from a hydrophobic segment and two hydrophilic segments. A method of producing a printed image having good durability and gloss is also disclosed.
