Abstract: An inkjet ink set includes a black ink, a yellow ink, a cyan ink, and a magenta ink. The magenta ink includes an ink vehicle including a polyurethane binder, and a dispersed magenta pigment in the ink vehicle. The magenta pigment is chosen from Pigment Red 282.

Abstract: A fixer fluid composition, for inkjet printing, and ink set containing it. A disclosed example fixer fluid composition includes up to about 1.5 wt % of surfactants, from about 1 to about 20 wt % of humectants, from about 3 to about 16 wt % of a metal carboxylate salt as fixer agent, and an acid in view of adjusting the pH of said composition to a pH between about 5.0 and about 7.0. A disclosed example of ink set includes, at least, an ink composition including a colorant dispersed in an ink vehicle and said fixer fluid.

Abstract: An inkjet fixer composition and a printing method and system used with the composition are disclosed herein. The composition includes: a) from 1 to 8 weight percent cationic polymer; and b) from 0 to 2 weight percent of at least one surfactant selected from the group consisting of nonionic surfactant, cationic surfactant and combinations thereof; and c) an aqueous liquid vehicle. Upon overprinting the fixer composition with an ink-jet ink on a substrate, the fixer composition vehicle and the ink-jet ink vehicle form a vehicle mixture on the substrate after which the vehicle mixture penetrates into the substrate, and an ink image is formed on the substrate.

Abstract: A fixer fluid for an inkjet ink set includes an aqueous vehicle, and a tri-alkyl-substituted amine-N-oxide. The fixer fluid also includes an acid, a cationic polyelectrolyte, or combinations of the acid and polyelectrolyte(s).

Abstract: The invention relates to an inkjet fixer composition and a printing method and system used with the composition, the composition comprising: a) from 1 to 8 weight percent cationic polymer; and b) from 0 to 2 weight percent of at least one surfactant selected from the group consisting of nonionic surfactant, cationic surfactant and combinations thereof; c) an aqueous liquid vehicle wherein the fixer composition is non-wetting in relation to the substrate; wherein, upon overprinting the fixer composition with an ink-jet ink on a substrate, the fixer composition vehicle and the ink-jet ink vehicle form a vehicle mixture on the substrate after which the vehicle mixture penetrates into the substrate, and an ink image is formed on the substrate.

Abstract: Low corrosivity inkjet ink sets and fixer formulations, and methods of making an inkjet ink set with reduced corrosivity are disclosed herein. One exemplary fixer formulation includes water; a polycationic fixing agent; and a counterion, wherein the counterion is chosen to reduce the presence of halogen in the fixer.

Abstract: The present invention is a method comprising: providing a substrate; solvent coating onto the substrate a composition comprising a curable, highly aromatic, organic matrix material and porogens which are cross-linked nanoparticles consisting essentially of residual monomeric units derived from alkenyl functional and/or alkynyl functional aromatic monomers; and heating the coated substrate to a temperature no greater than 390° C., preferably no greater than 370° C., to cure the matrix and remove substantially all of the porogen material in a relatively short period of time to form small uniform pores in the cured highly organic matrix material.
