改善列印头寿命的墨水;INK FOR IMPROVING PRINTHEAD LIFETIME

摘要

一种喷墨墨水，其包括：墨水载剂、着色剂；及具有烷氧基化羟基之炔系化合物，其中该羟基为一级或二级羟基，及该炔系化合物不具亲脂性基团。曝露于此等墨水之具有电阻式加热器元件的列印头具有比参考墨水更长的寿命。; 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.
