    摘要： An ink set includes a first ink and a second ink, where each of the inks has a conductivity that is less than 200 pS/cm. The first ink includes a first pigment of a first color; a carrier fluid; and a concentration of a dispersant. The second ink includes a second pigment of a second color that is different from the first color; the same carrier fluid as the first ink; and substantially the same concentration of the dispersant as the first ink.

    摘要： Liquid electrophotographic ink concentrates and methods of preparing the same are disclosed herein. An example of the method includes preparing a mixture of ink components using a first predetermined thermal profile. The ink components include a resin, a pigment, and a carrier. The method further includes preparing a microfluidizer with a composition at a temperature within a predetermined range and processing the mixture in the prepared microfluidizer to form the concentrate. Processing the mixture includes pressure-feeding the mixture into the prepared microfluidizer, passing the mixture through the prepared microfluidizer for a predetermined number of times, and utilizing a second predetermined thermal profile while passing the mixture through the prepared microfluidizer. A viscosity modifier is added to the mixture before and/or during the processing of the mixture.

    摘要： The present disclosure is drawn to methods and compositions directed at durable ink-jet inks. As such, an ink-jet ink can comprise a liquid vehicle, a colorant dispersed or dissolved in the liquid vehicle, a high Tg polymer having a Tg of at least 45° C. dispersed in the liquid vehicle, and a near-infrared absorbing dye in the liquid vehicle. The ink can be formulated such that when printed on a substrate and irradiated with a near-infrared energy source, the near-infrared absorbing dye generates enough heat to uniformly melt the high Tg polymer, thereby enhancing the durability of ink-jet ink printed on the substrate.

    摘要： An inkjet printing composition comprises an aqueous liquid vehicle; at least one pigment having a concentration of about 1 to 5 wt %; and a latex polymer having a concentration of about 2.5 to 8 wt % and comprising a polymerized mixture of styrene, butyl acrylate, at least one of methacrylonitrile and acrylonitrile, methacrylic acid, and ethylene glycol dimethacrylate. An inkjet ink printing system comprises a vinyl medium; the at least one inkjet printing composition; and a heating device, wherein the system is configured such that upon applying heat from the heating device to the inkjet ink printed on the vinyl medium, the latex particles fuse, thereby forming a printed image with a film encapsulating at least a portion of the pigment on the vinyl medium. A method of forming a printed image of the latex polymer using the inkjet ink printing system is also provided.
