IMPROVED PROCESSING COMPOSITIONS FOR COLOR TRANSFER PROCESSES Abstract of the Disclosure Improvements in the physical characteristics of a photographic assemblage, especially an integral transfer element, are obtained by employing an alkali metal salt in the alkaline processing composition used to process the assemblage. The anion of the salt has a solubility in relation to that of sulfate such that after processing in the presence of calcium and sulfate ions, calcium will combine with said anion in preference to sulfate at any given pH. Especially preferred salts are alkali metal fluorides or oxalates. - 1 -
