Abstract

A process for printing a substrate comprising applying thereto an ink by means of an ink jet printer, wherein the ink comprises a latex binder, a liquid medium comprising water and organic solvent, and polymer-encapsulated pigment particles comprising a carboxy-functional dispersant crosslinked around a pigment core by a crosslinking agent, wherein the ink has a minimum film-forming temperature below 70° C. Inks are also claimed. The process and inks are useful for printing temperature-sensitive substrates, e.g. foil balloons and wrapping materials for special occasions.
