Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
