ABSTRACT:
The present invention provides nonaqueous thermaljet ink compositions having improved print uniformity, drying time, and waterfastness. The nonaqueous thermaljet ink compositions of the present invention are formulated by combining a solvent dye colorant and two or more miscible nonaqueous solvents, at least one being volatile and one being nonvolatile. More specifically, the solvents are combined in such relative concentrations that drying time is reduced when the composition is thermaljet printed onto a substrate and solubility of the dye is not seriously compromised when the volatile solvent evaporates.
