摘要： The present invention provides an inkjet ink comprising: 5-40% by weight of an N-vinyl monomer selected from N-vinyl caprolactam, N-vinyl pyrrolidone, N-vinyl piperidone, N-vinyl carbazole, N-vinyl formamide, N-vinyl indole, N-vinyl imidazole, N-vinyl acetamide, and mixtures thereof, based on the total weight of the ink; one or more difunctional monomers in which the only radiation-curable functional groups present in the monomer are (meth)acrylate groups; 9% or less by weight of a monofunctional monomer, other than the N-vinyl monomer, together with a multifunctional monomer, based on the total weight of the ink; a radical photoinitiator; and a colouring agent. The present invention also provides a method of inkjet printing using the inkjet ink of the present invention and use of an N-vinyl monomer selected from N-vinyl caprolactam, N-vinyl pyrrolidone, N-vinyl piperidone, N-vinyl carbazole, N-vinyl formamide, N-vinyl indole, N-vinyl imidazole, N-vinyl acetamide, and mixtures thereof to increase the cure speed of an inkjet ink comprising one or more of difunctional monomers.

摘要： The present invention provides a method of multi-pass inkjet printing comprising: (i) providing an inkjet ink comprising a radiation-curable monomer and a photoinitiator; (ii) jetting the ink via a printhead on to a substrate, wherein the ink is applied in multiple passes of the printhead with respect to the substrate, with each pass jetting a portion of ink in a layer on the substrate, with a first layer being jetted directly on to the substrate and subsequent layers being jetted onto the preceding layer, to build an image formed of the multiple layers; and (iii) exposing all of the layers of ink to actinic radiation to cure the ink, wherein the order of jetting the layers and curing is that pairs of layers are applied to the substrate without exposing the first layer of the pair to actinic radiation prior to the second layer of the pair of layers being applied, curing the pair of layers simultaneously by exposing the pair of layers to actinic radiation, and repeating until the image is formed.
