Beschreibung
Zusammenfassung:	A colourless inkjet ink composition comprises of at least 30% by weight of monofunctional (meth)acrylate monomer based on the total weight of the ink; and at least 3% by weight of photoinitiator based on the total weight of the ink, wherein the photoinitiator comprises an alpha-hydroxy ketone, and one or more of a bis-acyl phosphine oxide, a thioxanthone and an alpha-amino ketone. The monofunctional (meth)acrylate monomer can be selected from cyclic TMP formal acrylate (CTFA), phenoxyethyl acrylate (PEA), isobornyl acrylate (IBOA), tetrahydrofurfuryl acrylate (THFA), dicyclopentenyl oxyethyl acrylate, 2-(2-ethoxyethoxy)ethyl acrylate, octadecyl acrylate, tridecyl acrylate, isodecyl acrylate (iso-decyl A), lauryl acrylate or combinations thereof.
