Patent ID: 7135267

Claim:
A photo-imageable precursor composition comprising: finely divided particles of inorganic material comprising: (a) electrically functional powders selected from electrically conductive, resistive, and dielectric particles; and (b) inorganic binder having a glass transition temperature in the range of from 325 to 600° C.; dispersed in: an organic medium comprising; (c) an aqueous developable, non-photosensitive polymer which is a copolymner, interpolymer or mixture thereof, wherein each copolymer or interpolymer comprises (1) a nonacidic comonomer comprising a C 1-10 alkyl acrylate, C 1-10 alkyl methacrylate, styrenes, substituted styrenes or combinations thereof and (2) an acidic comonomer comprising ethylenically unsaturated carboxylic acid containing moiety; and (d) a bi-functional UV-curable monomer having a first and second functional unit, wherein the first functional unit is a vinyl group and the second functional unit is capable of forming a chemical bond by reaction with the carboxylic acid containing moiety, and (e) further comprising an epoxide monomer.
