Abstract

1356978 Silver halide photographic emulsions EASTMAN KODAK CO 12 Aug 1971 [13 Aug 1970] 37909/71 Heading G2C A photographic silver halide emulsion comprises grains, having an average diameter not greater than 0À2 micron, which have been spectrally sensitized with a methine dye and chemically sensitized with at least 50 mg of a noble metal e.g. gold, per mole of silver halide and a weight of labile sulphur from one fifteenth to one seventyfifth of the weight of the noble metal.
