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.
