ABSTRACT:
The difficulties in the casting process of photographic gelatin containing layers caused by increases in the viscosity of the casting solution due to the premature cross-linking of gelatin can be prevented if a compound containing at least one vinyl sulfone group and at least one sulfonyl ethyl sulfate group in the form of their salts is incorporated in the casting composition of the gelatin-containing layer(s) or in the gelatin-containing layer(s) applied to the layer support.
