    摘要: Improved chemical sensitization is provided by a photographic silver halide emulsion chemically sensitized with a water-soluble gold(I) compound represented by the formula:

    wherein Z represents the substituted or unsubstituted nitrogen and carbon atoms necessary to complete a 5- or 6-member imide nucleus; and M is a cation. Such a chemically sensitized photographic silver halide emulsion is useful in a photographic silver halide element and process.

    摘要: A photographic silver halide material is chemically sensitized with a soluble gold(I) compound of the formula:
    AuL₂⁺X⁻ or AuL(L¹)⁺X⁻
    wherein L is a mesoionic compound; X is an anion; and L¹ is a Lewis donor ligand. The novel gold(I) compounds possess properties which are advantageous compared to the properties of previously known gold compounds.
