ABSTRACT:
A photographic recording material for use in redox amplification comprises a support having thereon a plurality of emulsion layers, each emulsion layer containing a color-forming coupler, and wherein the activity of the couplers is from 45 to 70% as measured by the citrazinic acid method. These materials may be developed by a redox development step which may be followed by a bleach-fix step without any intervening step. Staining is eliminated with the use of these photographic materials.
