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