ABSTRACT:
Proteinaceous material such as gelatin is hardened by treatment with an aqueous solution of the partial hydrolysis product of a 2,4-dichloro-6-alkoxy-S-triazine with a water-soluble tertiary phosphate and/or a water-soluble borate, wherein the 2,4-dichloro-6-alkoxy-s-triazine corresponds to the formula: ##STR1## wherein R is a lower alkyl or alkoxyalkyl group. 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.
