INK-JET INK COMPOSITION

摘要

A water-based ink-jet ink composition comprises: (a) an emulsion of a cross-linkable oligomer or polymer comprising at least one reactive carbonyl group capable of reacting with a cross-linking agent (b); (b) a cross-linking agent which cross-links the oligomer or polymer in (a) upon drying of the compositon; and (c) a resolubilising polymer. This composition has a viscosity at 25 DEG C of no more than 50 centipoise, preferably no more than 30 centipoise, more preferably no more than 15 centipoise, and especially no more than 5 centipoise.
