Ink for improving printhead lifetime

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 su...

More Information
Summary: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.
