ABSTRACT:
An inkjet printer head formed from a photoimageable organic material. This material provides for a spin-on epoxy based photoresist with image resolution and adhesion to hard to bond to metals such as gold or tantalum/gold surfaces that are commonly found in such printer applications. When cured, the material provides a permanent photoimageably defined pattern in thick films (>30) that has chemical (i.e high pH inks) and thermal resistance.
