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, citric acid or salts of citric acid are utilized as an effective inhibitor of homopolymerization in such hardening compositions.
