Abstract

A poly-p-xylylene coating has been found to demonstrate superior properties as a thermal ink-jet adhesive material in combination with resistor assemblies employed in thermal ink-jet printheads. This material evidences better adhesion for securing the orifice plate to the barrier material used to form the ink firing chambers within the printhead and superior corrosion resistance to thermal ink-jet inks, compared to other coating materials.
