Summary:Photographic recording materials of which the binder layers consist of protein-like binders which have been hardened in the usual way show reduced susceptibility to the effect of formaldehyde when-in addition to the usual hardeners-low molecular weight monofunctional compounds which are capable of reacting with free primary amino groups of the binder under casting and/or storage conditions without causing additional hardening are allowed to act on the binder.
