ABSTRACT:
An ink jet ink composition useful for printing on plain paper at room temperature comprises a colloidal suspension of a nonaqueous solvent (e.g. selected glycol ethers) and dispersed particles comprising a natural resin or synthetic polymer which is insoluble in water but soluble in the solvent at room temperature, and a dyestuff which is soluble in or bindable to the resin or polymer at room temperature but substantially insoluble in the solvent at room temperature. The ink composition is fluid and has a low viscosity at room temperature.
