Abstract: The present invention provides an inkjet ink comprising: 6-35% by weight of NYC; 5-60% by weight of PEA; 15-35% by weight of a CS.12 alkane dial di(meth)acrylate; a radical photoinitiator; and a colorant, wherein the percentages by weight are based on the total weight of the ink. The present invention further provides an inkjet ink set wherein at least one of the inks in the set, preferably all of the inks in the set, is an inkjet ink as defined above. Furthermore, the present invention provides a method of inkjet printing comprising inkjet printing the inkjet ink or inkjet ink set as defined above onto a substrate and curing the ink.

Abstract: The present invention provides an inkjet ink comprising: 6-35% by weight of NVC; 5-60% by weight of PEA; 15-35% by weight of a C8.12 alkane diol di(meth)acrylate; a radical photoinitiator; and a colorant, wherein the percentages by weight are based on the total weight of the ink. The present invention further provides an inkjet ink set wherein at least one of the inks in the set, preferably all of the inks in the set, is an inkjet ink as defined above.

Abstract: 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.
