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.
