ABSTRACT:
A bleach-fix composition for use in photographic processing comprising a polycarboxylic acid bleaching agent, a thiosulfate fixing agent, and a carbonyl bisulfite adduct. The carbonyl bisulfite adduct functions as a stabilizing agent which retards sulfurization of the bleach-fix composition and thereby prolongs its useful life.
