ABSTRACT:
Color reversal photographic films are processed using a reversal solution comprising stannous ion and a quaternary ammonium compound as the sole biocide, to reduce formation of biogrowth. The quaternary ammonium compound is present at very low concentrations of 1 to 20 ppm, and is preferably myristyltrimethyl ammonium bromide because it avoids precipitates with components that leach out of processed films.
