Abstract
Radiation curable phase change ink comprising an ink vehicle that includes at least one curable carrier, at least one gellant, at least one curable wax and at least one photoinitiator. In a method of forming an image with the ink, the radiation curable phase change ink is melted, then jetted onto an image receiving substrate, wherein the radiation curable phase change ink forms a gel state, and exposed to ultraviolet light to cure the curable components of the radiation curable phase change ink. The wax cures into the structure of the ink, thereby generating a robust image of excellent gloss.
