Abstract

1413498 Photographic silver halide emulsions EASTMAN KODAK CO 30 Nov 1972 [2 Dec 1971] 55361/72 HeadingG2C Photographic silver halide grains containing externally dispersed, S, Se or Te ions at a minimum of 13 parts by weight per million parts of silver (i.e. insufficient to confer internal sensitivity) are produced by reacting silver ions with halide ions in a precipitation medium containing a labile Se, Te or S compound. The grains may be chemically surface sensitized (e.g. with gold sensitizers) after formation of the grains. Specified labile compounds are thio-, seleno-, or telluro-, ureas, thio-, seleno- or telluro-carbamides, iso- (thio or telluro)- cyanates, (e.g. allyl isothiocyanate) tellurocyanates, colloidal se, diethyl selenide, sodium sulphide and sodium thiosulphate. The grains are preferably dispersed in a polymer and coated on a support and used as a developing-out emulsion. The addition of the S, Se or Te ions increases the speed and gamma of the emulsion.
