    摘要： The present invention is directed to aqueous based ink compositions for ink jet printing on offset media and offset ink comprising various combinations of nonionic surfactants. Such formulations include effective amounts of an ink colorant and a nonionic surfactant having an HLB value from about 4 to 14. Optionally, additional nonionic surfactants, solvents, and binders can be added. In another formulation, an effective amount of an ink colorant, at least two nonionic surfactants, each being present at from about 0.01% to 10% by weight (preferably 0.01% to 2% by weight) and an effective amount of at least one binder (such as an acrylate binder) is disclosed.

    摘要： In a four pen ink jet printer comprising cyan, yellow, magenta, and black inks, a clear liquid is applied to printed ink on a print medium via a fifth pen, thereby fixing the colorants, which in turn improves the durability of the printed ink. The clear fixer fluid comprises at least one organic acid and, optionally, a salt of at least one polymeric acid.

    摘要： A fixer fluid having reduced kogation. The fixer fluid includes at least one phosphate ester surfactant and at least one cationic polymer, wherein the fixer fluid is formulated so that the at least one phosphate ester surfactant does not precipitate with the at least one cationic polymer. The at least one phosphate ester surfactant may be an anionic phosphate ester surfactant or an amphoteric phosphate ester surfactant. If the at least one phosphate ester surfactant is an anionic phosphate ester surfactant, it may have greater than or equal to approximately 2 moles of ethylene oxide per mole of the phosphate ester surfactant. The present invention also relates to an inkjet ink having reduced kogation and a method of producing a fixer fluid having reduced kogation.

    摘要： Compositions, systems, and methods for providing smudge resistant and durable ink-jet images having good optical density are provided. Specifically, a system for printing durable ink-jet ink images can comprise a first ink-jet pen containing an ink-jet ink and a second ink-jet pen containing a fixer composition. The ink-jet ink can comprise a first liquid vehicle and a colorant. The fixer composition can comprise a second liquid vehicle, and from 0.5 wt % to 5 wt % of a cationic copolymer of an epihalohydrin and an amine. Upon overprinting or underprinting the fixer composition with respect to the ink-jet ink on a substrate, a durable image can be formed.
