PHOTOGRAPHIC COLOR DEVELOPER REPLENISHING CONCENTRATES

摘要

Improved one-part concentrated color developing replenishers and methods of preparation thereof comprising a photographically inert single ring heterocyclic amide. The replenisher concentrates are packaged in a single un it which upon dilution provides ready-to-use replenishing solutions for photographic materials. The concentrated replenishers are characterized by a one-part multi-phase concentrate wherein developing agents are retained in a n upper phase and protected from deterioration which normally occurs in the highly alkaline lower phase.
