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.
