Abstract
Abstract 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 Lewis donor ligand. The novel gold(I) compounds possess properties which are advantageous compared to the properties of previously known gold compounds.
