Abstract

A curable phase change ink composition that includes an ink vehicle including at least one isosorbide monomer having at least one functional group. Also described is an ink printing device that includes a curable phase change ink composition for printing onto a substrate, an ink jetting device, and a curing device providing radiation that cures the curable phase change ink composition. The curable phase change ink composition of the ink printing device includes an ink vehicle including at least one isosorbide monomer having at least one functional group.

Claims
