Tellurium imaging composition including base

摘要

Imaging compositions employing a tellurium compound, a reductant precursor, a masked reducing agent and a source of labile hydrogen are improved by the inclusion of a base which may be inorganic or organic. Suitable inorganic bases include alkali metal hydroxides, alkaline earth metal hydroxides and ammonium hydroxide. Suitable organic bases include amines and heterocyclic nitrogen atom containing compounds.
