Abstract: Provided is a curable ink composition, in particular a curable inkjet ink composition. The ink composition has a dye monomer, a carrier monomer and an initiator. The dye monomer has a chromophore moiety that is covalently bonded to at least one polymerizable functional group and is present at 1.0 wt % or more based on total weight of the ink composition. The carrier monomer has at least one polymerizable functional group and is present in at 50 wt % or more based on total weight of the ink composition. The ink compositions are suitable for radiation curing such as UV curing and have good cure properties or light fastness properties.

Abstract: Provided is an ink composition for use in drop on demand inkjet printing such as piezoelectric drop on demand inkjet printing. The ink composition has a phosphine oxide initiator and benzyl acrylate. The amount of benzyl acrylate is less than 40 wt % based on the total weight of the ink composition and the total amount of mono-functional monomers is less than 45 wt % based on the total weight of the ink composition. The phosphine oxide initiator is a bis-acyl phosphine oxide, a benzoyl alkyl phosphinate, or a mixture thereof. The ink compositions are suitable for radiation curing and have good cure properties or good adhesion properties.
