Some Considerations of Eastman Color Print Film Dye Stability

Paul Horowitz, William R. Weller

The dyes in Eastman Color Print Film are quite satisfactory for stability when the film is processed according to recommended procedures. Their stability under conditions of high temperature and high humidity can, however, be seriously affected by retained hypo and/or abnormal pH of the processed emulsion. These conditions can be prevented by following recommended processing procedures, particularly the final wash. A simple method of measuring the emulsion pH directly on the processed film, and emulsion pH control parameters are described.
