A novel hot melt impulse ink jet ink is disclosed which comprises a C.sub.20 -C.sub.24 acid or alcohol containing vehicle, preferably behenic acid, and a suitable coloring agent. The preferred ink has a melting point above about 65.degree. C., exhibits very good jettability, good heat stability at a reservoir temperature of 90.degree. C., good material compatability, and an improved print quality. The preferred ink comprises about 80% natural behenic acid, 15% of a ketone (such as stearone), 3% coloring agent, and 2% of a plasticizer intended to improve print quality. The subject inks are jetted at relatively high temperatures (80.degree.-90.degree. C.) using impulse ink jet devices. Upon impact with the target substrate the subject inks freeze to produce a high quality print having a smear resistance approximately equal to IBM copy, and cracking resistance better than such copy.
