Abstract (en)
[origin: US5034249A] Layers containing proteinaceous binders, in particular gelatin layers of the kind used, for example, in photographic recording materials, are hardened by means of an instant hardener by casting a hardening system composed of at least two layers over the layer of binder, the lower of these two layers containing the instant hardener while the upper layer, which may be applied together with or immediately after the lower layer, contains a protein-containing binder but no hardener. The hardened layers have improved surface properties (wet scratch resistance, antifriction properties).
