Abstract
A photographic silver halide material is chemically sensitized with a soluble gold(I) compound of the formula: EQU AuL.sub.2.sup.+ X.sup.- or AuL(L.sup.1).sup.+ X.sup.- wherein L is a mesoionic compound; X is an anion; and L.sup.1 is a Lewis donor ligand. The novel gold(I) compounds possess properties which are advantageous compared to the properties of previously known gold compounds.
