ABSTRACT:
Noble metal silver-precipitating nuclei are prepared by reducing a noble metal salt or complex in the presence of a first polymer with a Sn.degree. colloid formed by the non-aqueous borohydride reduction of a tin salt in the presence of an organic solvent for the tin salt and a nitrogen-containing metal chelating polymer. The invention is also directed to film units employing said nuclei.
