Abstract: The present disclosure relates to an inkjet printing process that comprises inkjet printing an inkjet ink composition onto a substrate to form a printed inkjet ink layer. The inkjet ink composition comprises a colorant, a curable polyurethane dispersion, a photoinitiator and water, wherein the amount of curable polyurethane dispersed in the inkjet ink composition is 0.1 to 30 weight %. A radiation-curable overcoat composition is applied over the printed inkjet ink layer as an overcoat layer. The overcoat composition comprises a curable polyurethane dispersion, a photoinitiator and water. The printed inkjet ink layer is then cured on the substrate by exposing both the overcoat layer and inkjet ink layer on the substrate to radiation.

Abstract: Aspects of the present disclosure relate to a printable medium including a polyurethane dispersion. As an example, a printable medium may include a fabric base substrate, with an image-side and a back-side. A film-forming layer may be applied to the image-side of the fabric base substrate, including an anionic polyurethane dispersion having a reactive group on a backbone of the polyurethane dispersion and a reactive group on a capping unit of the polyurethane dispersion. An ink-receiving coating layer may be applied over the film-forming layer, including a crosslink agent.
