ABSTRACT:
A method of chemical sensitisation which comprises providing a silver halide emulsion containing negative-acting silver halide grains, and adding to said silver halide emulsion a sulphur releasing organic polymer having multiple sulphur releasing groups per polymer molecule. The polymer preferably has at least 10 sulphur releasing groups per molecule which may be selected from thiocarbonate, dithiocarbonate, trithiocarbonate, dithioester, thioamide, thiocarbamate, dithiocarbamate, thiouram, thiourea, dithiooxamide, thioketone and trisulphide.
