Abstract:
1. A thermally developable imaging material comprising a support and having thereon one or more thermally developable imaging layers, an interlayer over said one or more thermally developable imaging layers, and an outermost protective layer over said interlayer, said one or more thermally developable imaging layers comprising a first hydrophilic binder or water-dispersible latex polymer and in reactive association: a) a source of reducible silver ions comprising an organic silver salt, and b) a reducing agent for said reducible silver ions, said outermost protective layer comprising a second hydrophilic binder, and said interlayer comprising a negatively-charged or positively-charged latex polymer other than a carboxy-containing latex polymer, said negatively-charged or positively-charged latex polymer comprising at least 50% by dry weight of total interlayer film-forming components and from about 0.4 to about 20 mol % of recurring units derived from ethylenically unsaturated polymerizable monomers comprising an ionic moiety, wherein said source of reducible silver ions is a silver salt of an N-heterocyclic compound.
