Abstract: A phase change ink includes an ink vehicle that includes at least one curable carrier, at least one gellant, at least one wax and at least one alkoxysilane monomer. In a method of forming an image with the ink, the phase change ink is melted, then jetted onto an image receiving substrate, wherein the phase change ink forms a gel state, and exposed to ultraviolet light to cure the curable components of the phase change ink. The alkoxysilane participates in crosslinking to form silicon-oxygen-silicon bonds, thereby producing an ink with advantageous stability and high image quality.
