Abstract: An inkjet ink includes: an ink vehicle; a colorant; and an acetylenic compound having an alkoxylated hydroxyl group, wherein the hydroxyl group is a primary or secondary hydroxyl group and the acetylenic compound is absent a lipophilic group. Printheads having resistive heater elements exposed to such inks have prolonged lifetimes compared to reference inks.

Abstract: A method of printing from an inkjet nozzle device having a thermal actuator. The method includes the steps of supplying a fluid to the inkjet nozzle device, the fluid comprising an acetylenic compound; and repeatedly actuating the thermal actuator so as to eject fluid droplets from a nozzle opening of the inkjet nozzle device. The acetylenic compound is present in an amount sufficient to increase the lifetime of the inkjet nozzle device.
