Abstract:
An ink jettable ink composition, comprising:(a) a radiation curable component comprising a radiation curable, reactive diluent having a surface tension of from about 20 dynes/cm to about 50 dynes/cm at printhead operating temperature; (b) one or more oligo/resins; (c) from about 1 to about 15 weight percent of an ester solvent free of radiation curable moieties having a surface tension of from about 20 dynes/cm to about 50 dynes/cm at printhead operating temperature, wherein the solvent surface tension is no more than about the surface tension of the reactive diluent taken as a whole; and (d) an amount of a colorant effective to provide the ink when cured with a visually discernable optical characteristic.
