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.
