Claim:
A radiation-curable phase-change ink vehicle having improved gellant solubility, the ink vehicle comprising: at least a first co-monomer, at least a second co-monomer that is different from the first co-monomer, at least a first gellant comprising a curable epoxy-polyamide composite gellant, and at least a second gellant that is different from the a first gellant, wherein the first co-monomer and the second co-monomer are radiation-curable monomers, wherein the first co-monomer is present in an amount ranging from about 40 to about 70% by weight, relative to the total weight of the ink vehicle, and the second co-monomer is present in an amount ranging from about 20 to about 50% by weight, relative to the total weight of the ink vehicle, and wherein the first co-monomer is propoxylated neopentyl glycol diacrylate and the second co-monomer is caprolactone diacrylate or 2-phenoxyethyl acrylate.
