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.
