PHOTOIMAGEABLE NOZZLE MEMBERS AND METHODS RELATING THERETO

摘要

Nozzle members, such as for a micro-fluid ejection head, micro-fluid ejection heads, and a method for making the same. One such nozzle member includes a negative photoresist composition derived from a first di-functional epoxy compound, a relatively high molecular weight polyhydroxy ether, a photoacid generator devoid of aryl sulfonium salts, an adhesion enhancer, and an aliphatic ketone solvent. The nozzle member has a thickness ranging from about 10 microns to about 30 microns.
