ABSTRACT:
Organic acid sulfonates, such as sodium methane sulfonate, sodium 4-toluenesulfonate and sodium propene-1-sulfonate, serve as additives for use in thermal ink-jet inks to reduce kogation significantly. The addition of such substances essentially eliminates kogation for the life of ink pens.
