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 translation: 喷墨油墨包括：油墨载体; 着色剂 和具有烷氧基化羟基的炔属化合物，其中羟基是伯或仲羟基，炔属化合物不存在亲脂基团。 具有暴露于这种油墨的电阻加热器元件的打印头与参考油墨相比具有延长的使用寿命。
