ABSTRACT:
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 an oxidizing agent, hydroxylamine as an antioxidant, and to improve the stability of the solution under aeration conditions, an effective amount of a mono or di-N-substituted hydroxylamine. The molar ratio of hydroxylamine to N-substituted hydroxylamine may be from 1:200 to 100:1. The substituents in the mono- or di-N-substituted hydroxylamine may be substituted or unsubstituted monovalent organic groups having 1 to 12 carbon atoms.
