Aqueous developable photoimageable thick film compositions with photospeed enhancer

摘要

A photoimageable composition comprising finely divided particles of inorganic materials comprising functional phase particles selective from electrically conductive, resistive and dielectric particles; and inorganic binder dispersed in organic medium comprising an aqueous developable polymer; photoinitiation system; and a photospeed enhancer wherein the enhancer comprises a ratio of 30/70 to 70/30 mixture selected from stearic acid and palmitic acid; salt of stearate and salt of palmitate; stearic acid and salt of palmitate; salt of stearate and palmitic acid; and organic solvent.
