Abstract
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.
