Abstract: 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.
