INK, PROCESS AND USE

摘要

A process for printing an image on a substrate comprising applying to the substrate by means of an ink jet printer an ink comprising the components: i) an encapsulated pigment comprising a pigment core and a cross-linked dispersant shell; ii) a binder having a weight averaged molecular weight of at least 5,000 which is or comprises a polyurethane; and iii) a liquid vehicle; wherein the binder is chemically different from the dispersant in the shell. The process provides prints having good highlighter smear resistance. The inks print well and are especially stable.
