ABSTRACT:
An ink composition for use in ink-jet printing to print images on a substrate, the composition being formulated to include, as the resin component, a phenolic resole resin and, as the primary solvent, a lower alkanol. The composition is also formulated to contain a pigment or soluble basic dye, a resistivity control agent preferably in the form of hydroxylamine hydrochloride, an evaporation retardant, and a modifying resin. The use of a phenolic resole resin which is capable of undergoing cure on evaporation of the solvent provides a printed image having improved adherence to various printing substrates and can be formulated and dissolved in less toxic, lower alkanol solvents.
