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.

A thermal ink jet ink composition include a volatile organic solvent, a binder resin, a dye, a humectant in an amount less than 40% by weight of the thermal ink jet ink composition, and an additive for extending the decap time. The additive is present in an amount greater than 0.1% by weight of the thermal ink jet ink composition. The additive is selected from plasticizers, surfactants, aliphatic hydrocarbons, drying oils and mixtures thereof. The additive does not phase separate from the ink jet composition during application of the ink to a substrate in thermal ink jet printing.
