ABSTRACT:
Silver halide photographic color films can be effectively stabilized using a chemical stabilizing kit of two concentrated chemical solutions that are mixed and diluted at least 5:1 when used. Each concentrated chemical solution contains some of the necessary chemicals for the processing solution, but keeping them individually packaged prior to use prevents biocide instability and other problems when all of the chemical components are mixed in concentrated form. One concentrated chemical solution includes hexamethylenetetramine and an alcoholamine such as diethanolamine. The other concentrated chemical solution includes the biocide(s) and one or more surfactants.
