Abstract: Silver halide photographic elements for tanning development including tanning developers, which can diffuse into the gelatin layer containing them, can be improved if they are associated with non-diffusing hydroquinones. In the case where such tanning developer is hydroquinone or a derivative thereof, said elements include such diffusing hydroquinone associated with a hydroquinone derivative non-diffusing in the gelatin layer containing it. Such non-diffusing hydroquinones preferably are hydroquinones substituted with aliphatic chains containing a total of at least twelve carbon atoms and, more preferably, are dispersed in the layer dissolved in a high-boiling organic solvent.
