ABSTRACT:
A proteinaceous material such as gelatin is hardened by treatment with an aqueous solution of a partial hydrolysis product of cyanuric chloride that has been buffered with a water-soluble borate, e.g. sodium metaborate, potassium metaborate or ammonium metaborate.
The proteinaceous material can be a proteinaceous coating such as a photographic silver halide emulsion layer, a backing layer, a protective layer, a filter layer or any other photographic auxiliary layer.
