ABSTRACT:
Thick film layers for a micro-fluid ejection head, micro-fluid ejection heads, and methods for making micro-fluid ejection head and thick film layers. One such thick film layer is derived from a difunctional epoxy component having a weight average molecular weight ranging from about 2500 to about 4000 Daltons, a photoacid generator, an aryl ketone solvent, and an adhesion enhancing component. One such thick film layer has a cross-link density upon curing that increases the dimensional stability of the thick film layer sufficient to provide flow features therein having substantially vertical walls.
