Moisture Relationships of Photographic Film

Abstract

AbstractThe moisture content of photographic film is a critical feature that influences physical properties, mold growth, and chemical stability. It is characterized by the moisture equilibrium curve, which is a plot of the moisture content as a function of the relative humidity. The effect of temperature on the moisture equilibrium curve is the main thrust of this article, which discusses the practical implications of these data for accelerated incubation studies. The temperature effect on the rates of moisture conditioning on film in several practical storage configurations and enclosures is presented. Finally; data are given on the moisture protection afforded by different enclosures, leading to recommendations on the cold storage of photographic film.
