    Abstract: A transfix surface member for use in aqueous ink jet printer comprises a substrate. A conformance layer is disposed on the substrate layer. A surface layer comprising a siloxane polymer network is on the conformance layer. The siloxane polymer network comprises a plurality of diphenylsiloxane moieties and a plurality of polar moieties, the diphenylsiloxane moieties and polar moieties being bonded to the siloxane polymer network by one or more siloxane linkages. An indirect printing apparatus employing the transfix surface member is also disclosed.

    Abstract: The disclosed systems and methods provide an ink-based digital printing system for printing high quality images on a wide latitude of image receiving media. The disclosed systems and methods employ a UV curable base (transfix) layer deposited on an intermediate image transfer member that is then at least partially cured prior to an aqueous ink being deposited on the base layer to form a digital image thereon. Once the images are formed on the base layer, a drying device is optionally used to reduce a water content of the aqueous ink images on the base layer prior to transfer of the images to an image receiving media substrate. At transfer, the images and at least a portion of the base layer are transferred to the image receiving media substrate, the images being sandwiched between the portion of the base layer and the image receiving media substrate.

    Abstract: A polymer composition includes a first polymer layer containing a base polymer matrix, and a second polymer layer grafted onto the first layer. The second polymer layer contains a stimulus-responsive polymer, and the surface free energy of the stimulus-responsive polymer is adjustable from a first surface free energy state to a second surface free energy state when heated to a critical activation temperature. A method of preparing a polymer composition includes providing a first polymer layer containing a base polymer, and grafting a second polymer layer containing a stimulus-responsive layer onto the first layer. A method of printing an image involves applying an ink onto an intermediate transfer member containing a first polymer layer containing a base polymer matrix and a second polymer layer containing a stimulus-responsive polymer grafted onto the first layer, spreading the ink, inducing a property change of the ink, and transferring the ink to a substrate.
