UV CURABLE INK WITH IMPROVED ADHESION

摘要

The present invention is drawn to photo-curable ink-jet ink compositions, systems, and methods. One exemplary ink-jet ink composition includes a liquid vehicle, a milled pigment, a photo initiator and a halogenated polyolefin. In this embodiment, the addition of the halogenated polyolefin improves adhesion to a non-porous substrate or a low surface tension substrate such as polypropylene.
