Abstract
Abstract An ink-jet ink comprises a colourant, a polar conductive component and, as a major component of the liquid phase, one or more polymerisable monomers in which the conductive component is soluble. The polymerisable monomers may comprise, by weight of the ink, up to 70% monofunctional monomer, up to 70% difunctional monomer, and 0 to 10% tri- or higher-functional monomer.
