    摘要： A UV curable inkjet ink for inkjet printing tarpaulins including an pigment, a free radical photoinitiator and a polymerizable composition containing more than 90.0 wt % of monofunctional polymerizable compounds based on the total weight of the polymerizable composition, wherein the monofunctional polymerizable compounds include more than 5.0 wt % of a N-vinyl oxazolidinone (V); more than 12.0 wt % of a heterocyclic acrylate (H) being a non-aromatic cyclic acrylate with all heteroatoms being oxygen; and more than 23.0 wt % of a mixture of an aromatic acrylate (A) and an alicyclic acrylate (L); wherein the wt % of the monofunctional polymerizable compounds is based on the total weight of the UV curable inkjet ink; and wherein a weight ratio R=(H+A)/(V+L) is no more than 2.0. An inkjet printing method is also disclosed.

    摘要： A radiation curable inkjet ink containing at least one or two compounds selected from the group consisting of a polymerizable compound including a vinylether group or a vinylamide group, an amine synergist including an alkanolamine group or a dimethyl benzoate group, and a Norrish Type II photoinitiator including a photoinitiating moiety selected from the group consisting of a thioxanthone group, a benzophenone group, a ketocoumarin group and a camphorquinone group; and a singlet oxygen quencher including at least one specific amino-thioether group.
