Zusammenfassung:A free radical curable inkjet ink containing a colour pigment, a photoinitiator and polymerizable composition, wherein the polymerizable composition includes more than 88.0% of monofunctional polymerizable compounds based on the total weight of the polymerizable composition; wherein more than 13.0 wt % of a monofunctional polymerizable compound having a double bond density DBD of more than 7.00; wherein more than 35.0 wt % of a polyfunctional alkoxylated acrylate having a molecular weight MW of more than 310 based on the total weight of the polyfunctional polymerizable compounds; wherein non-aromatic cyclic monofunctional acrylates in an amount such that the ratio of the wt % of polyfunctional alkoxylated acrylate having a molecular weight MW of more than 310 to the wt % of non-aromatic cyclic monofunctional acrylates is larger than 0.35; and wherein the polymerizable composition has a double bond density DBD of no more than 5.55 mmol double bonds/g.
