Abstract
A radiation curable resin composition having improved flexibility. The radiation curable composition having from about 5 to about 50 weight percent of a difunctional polymeric compound; from about 1 to about 10 weight percent of a photoinitiator; from about 1 to about 10 weight percent of a flexibilizer agent, wherein the flexibilizer agent has a molecular weight ranging from about 400 to about 10,000; and about 30 to about 90 weight percent of the non-photoreactive solvent, wherein the weight percents are based on the total weight of the resin composition. Ink jet print heads and ink jet printing apparatusess comprising ink jet print heads utilizing the radiation curable resin compositions are also included.
