摘要： Photographic color developing compositions containing a primary aromatic amino color developing agent and a hydroxylamine compound are stabilised against decomposition of hydroxylamine and formation of sludge by incorporating stabilised chelating compounds of the formula:
wherein each R 1 is hydrogen, -CH 2 COOH or
each R 2 is hydrogen or -COOH
p is 0 or 1, and
X completes a substituted or unsubstituted aromatic nucleus.
The composition may also contain another different chelating agent, e.g. of the aminopolycarboxylic or aminopolyphosphonic acid type.-
