ABSTRACT:
The invention is generally accomplished by providing a method of chemical sensitization comprising providing a silver halide emulsion, and adding to the silver halide emulsion aqueous solid particle dispersion of a chemical sensitizing agent having a water and organic solvent insolubility (i.e., 50 mg/100 ml or less), and heating said emulsion wherein said chemical sensitizing agent comprises at least one member selected from the group consisting of gold compounds represented by Formula I:
