Abstract
The radiation curable ink compositions exhibit fasting curing, high flexibility and good adhesion to a broad range of substrates. The ink compositions include a dendritic or hyperbranched polyester acrylate component, which is present in an amount of 10-45% by weight and has a functionality of greater than 5. The compositions further include an oligomer component, a monomer component, a photoinitiator component, a colorant component, and an additive component. The compositions have a viscosity of not greater than 40 cP at 25° C. The radiation curable compositions are suitable for inkjet printing on a variety of substrates.
