Abstract: The present invention provides a white inkjet ink comprising: tricyclodecane dimethanol diacrylate; at least one of a difunctional urethane (meth)acrylate oligomer, (2-methyl-2-ethyl-1,3-dioxolane-4-yl)methyl acrylate and a polyethylene glycol diacrylate; a white pigment; and a monofunctional monomer, other than (2-methyl-2-ethyl-1,3-dioxolane-4-yl)methyl acrylate. The present invention further provides a method of inkjet printing comprising inkjet printing the inkjet ink of the present invention onto a substrate and curing the inkjet ink by exposing the inkjet ink to a curing source, preferably wherein the curing source is a UV LED light.

Abstract: The present invention provides a colorless inkjet ink composition comprising at least 30% by weight of monofunctional acrylate monomer based on the total weight of the ink and at least 3% by weight of a photoinitiator based on the total weight of the ink, wherein the photoinitiator comprises an ?-hydroxy ketone photoinitiator and wherein the ink comprises 0 to 6% by weight of acyl phosphine photoinitiator based on the total weight of the ink.
