All-purpose processing formulation for color negative materials
Abstract
A two-solution color processing system has been formulated that is more rapid than black-and-white processing and eliminates the need for ferricyanide bleach, one of the most objectionable pollutants discarded from photographic processing facilities. This all-purpose chemistry can be used to process all of the following color photographic emulsions: Kodacolor-X, Ektacolor-S, Vericolor-S, Aerocolor Negative, Ektacolor Internegative, Ektacolor Print Films, Ektacolor RC Paper and several reversal films processed to a negative. The access time as well as the number of processing steps, is markedly reduced when the ECOM chemistry is used. Negatives and transparency prints are processed in 1/5 the time required with conventional processing and paper processing time is reduced by 1/2 without degrading the color or stability characteristics of the processed emulsion.
