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.
提供了包括可还原碲化合物、还原剂前体、在基质中包含不稳定氢源的成像薄膜和制膜组合物。还原剂前体的化学式为##STR1##其中,Y.sub.1为烷氧基,Y.sub.2为氯或烷氧基,Y.sub.3为氢、氯或烷氧基。还提供了合成还原剂前体的方法。
