Stability of Cellulose Ester Base Photographic Film: Part I — Laboratory Testing Procedures
This article describes the studies done on the chemical stability of photographic film by incubation of a dozen different materials at five temperatures and four relative humidities (RH). Property changes were followed using Arrhenius plots. Predictions of useful life at room temperature storage were very dependent upon the property measured with base acidity being the most sensitive indicator. At 50% RH, the gelatin layer had greater stability than that of the base. There was no consistent difference between the stability of the uncoated base and emulsion-coated base.
