ABSTRACT:
Disclosed is a photographic element comprising a non-light sensitive layer containing elemental silver and a heterocyclic thiol compound having a Clog P of at least 2.0 but less than 12.0, provided that the ring system of the compound comprises a --N.dbd.C--S--H group or its tautomer and does not react with an oxidized developer. The invention provides improved minimum densities in imaging layers.
