Abstract
Disclosed is an ink jet ink composition suitable for printing on substrates holding high static electrical charges such as polyethylene and PVC films and tubes. The ink jet ink composition comprises an organic solvent having a boiling point greater than 56° C., a binder resin soluble in the organic solvent, a colorant soluble in the organic solvent, and a polyvinylbutyral resin. Also disclosed is a method of printing images on such plastic substrates and a method for reducing microsatellite formation during ink jet printing. The ink jet ink composition provides improved print quality and reduced need for cleaning the nozzle.
