Abstract[English]
An inkjet ink includes an aqueous-based ink vehicle and 5 to 250 ppm of a polyvinyl alcohol. The ink is useful for improving the lifetime of inkjet printheads, especially printheads with inkjet nozzle devices having resistive heater elements susceptible to failure by corrosion.[French]
