Abstract: A textile printing system includes a fabric substrate, an inkjet printhead in fluid communication with a reservoir containing a UV-curable ink composition to eject a UV-curable ink composition, and a UV-curing energy source positioned to cure the UV-curable ink composition upon being ejected onto the fabric substrate. The UV-curable ink composition includes from 50 wt % to 95 wt % water, from 4 wt % to 49 wt % organic co-solvent, from 0.5 wt % to 12 wt % pigment, wherein the pigment has a dispersant associated with a surface thereof, and from 0.5 wt % to 20 wt % of a polyurethane particles. The polyurethane particles include a polyurethane strand including a polyurethane backbone with a pendant reactive (meth)acrylate-containing diol group and terminal end cap groups, and the terminal end cap groups are independently selected from a monoalcohol, a monoamine, an acrylate, a methacrylate, or a combination thereof, for example.

Abstract: The present disclosure is drawn to reactive polyurethane dispersions. In one example, a reactive polyurethane dispersion can include a polymer strand having a polymer backbone that has two ends terminating at a first capping unit and a second capping unit. The polymer backbone can include polymerized monomers including a reactive diol and a diisocyanate. The reactive diol can be an acrylate-containing diol, a methacrylate-containing diol, an acrylamide-containing diol, a methacrylamide-containing diol, or combination thereof. The first capping unit can be an acrylamide-containing monoalcohol or methacrylamide-containing monoalcohol reacted with an isocyanate group of the diisocyanate. The second capping unit can be an ionic stabilizing group.

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 inkjet printed over the printed inkjet ink layer as an overcoat layer. The overcoat composition comprises a curable polyurethane dispersion, a photoinitiator and water, wherein the amount of curable polyurethane dispersed in the overcoat composition is 0.1 to 30 weight %. The printed inkjet ink layer is cured by exposing both the printed inkjet ink layer and the overcoat layer on the substrate to radiation.
