Abstract

A stabilizing bath that provides image stability and uniform drainage of excess fluid to prevent drying spots and that reduces or eliminates the formation of residue on the base side of color negative films is comprised of hexamethylenetetramine, a nonionic polyethoxylated surfactant, and an anionic sulfate or sulfonate surfactant. The stabilizing bath is used as the final processing bath prior to drying. The nonionic surfactant provides uniform drainage of excess fluid and the anionic sulfate or sulfonate surfactant functions to reduce or eliminate the formation of residue on the base side of color negative films.
