A composition of a photosensitive silver conductor tape comprising: (1) an admixture of finely divided inorganic solids comprising (a) finely divided particles of silver solids; (b) finely divided particles of inorganic binder having a glass transition temperature (Tg) of 325-700° C., the admixture of inorganic solids being dispersed in (2) an organic medium comprising a solution of (c) a organic polymeric binder which is a copolymer, interpolymer or mixture thereof selected from (1) nonacidic comonomers comprising butylmethacrylate or mixtures of butylmethacrylate and C1-10 alkyl acrylates, C1-10 alkyl methacrylates, styrene, substituted styrenes, or combinations thereof and (2) acidic comonomers comprising ethylenically unsaturated carboxylic acids containing moiety that are at least 15 wt. % of the total polymer weight; and having a Tg of 50-150° C. and weight average molecular weight in the range of greater 50,000 but less than or equal to 300,000; (d) a photoinitiation system; (e) a photohardenable monomer; and with the proviso that the composition is fireable in an oxidizing or substantially nonoxidizing atmosphere at temperature of no higher than 700° C.
