Beschreibung
Zusammenfassung:	A UV LED free radical curable inkjet ink containing an organic colour pigment; an acylphosphine oxide photoinitiator; monofunctional polymerizable compounds including vinyl methyl oxazolidinone; and one or more polyfunctional polymerizable compounds; wherein: the double bond density DD is between 5.28 and 5.78 mmol double bonds/g; the content of monofunctional polymerizable compounds is between 84 and 98 wt % based on the total weight of the polymerizable composition; and the content of vinyl methyl oxazolidinone is at least 13.3 wt % based on the total weight of the polymerizable composition.
