Reductant precursor for tellurium imaging compositions

Abstract

Imaging films and film-forming compositions are provided which include a reducible tellurium compound, a reductant precursor, a source of labile hydrogen incorporated in a matrix. The reductant precursors are of the formulae ##STR1## where Y.sub.1 is alkoxy, Y.sub.2 is chloro or alkoxy and Y.sub.3 is hydrogen, chloro or alkoxy. Methods are provided for synthesizing the reductant precursors.
