Abstract: Herein is disclosed a method of transfer inkjet printing comprising jetting a radiation curable inkjet ink onto an intermediate transfer member of an inkjet printer to form an image; irradiating the radiation curable inkjet ink on the intermediate transfer member to form an at least partially cured image; and transferring the at least partially cured image to a substrate to form a printed substrate. Herein is also disclosed a transfer inkjet printing apparatus adapted, in use, to perform the method.

Abstract: The present disclosure is drawn to polyurethane dispersions. In one example, a polyurethane dispersion can include a polyurethane with a polymeric ionic side chain and a polymeric non-ionic side chain. The polyurethane can be formed of polymerized monomers including a diisocyanate, a first polymeric diol, and a second polymeric diol. The first polymeric diol can include a first polymer chain replacing a hydrogen atom of a thiol group of a 1-thioglycerol molecule. The first polymer chain can include a block of a polymerized ionic group-containing vinyl monomer. The second polymeric diol can include a second polymer chain replacing a hydrogen atom of a thiol group of a 1-thioglycerol molecule. The second polymer chain can include a block of a polymerized non-ionic vinyl monomer, and the second polymer chain can be devoid of ionic groups.
