<p>A process for the redox development of an imagewise exposed photographic recording material comprises developing the photographic material in a redox developer/amplifier solution containing peroxide as oxidising agent and hydroxylamine as antioxidant and to improve the stability of the solution under aeration conditions an effective amount of a mono or di- N-substituted hydroxylamine is included. The molar ratio of hydroxylamine to N-substituted hydroxylamine may be from 1:200 to 100:1, preferably from 1:10 to 10:1. The substituents in the mono or di N-substituted hydroxylamine may be monovalent organic groups containing from 1 to 12 carbon atoms.</p> |
