Abstract
Hydrophilic colloids, such as gelatin, which are employed in the manufacture of photographic elements are commonly treated with a hardening composition, among the most useful of which are hardening compositions containing vinyl sulfone hardening agents such as bis(vinylsulfonyl)methane. In accordance with this invention, a sulfate, such as sodium sulfate, is utilized as both an effective conductivity marker and an effective inhibitor of homopolymerization in such hardening compositions.
