Abstract (en)
[origin: EP0709725A1] The present invention concerns a silver halide emulsion, and more particularly a silver halide emulsion which resolves the problem of desensitisation which can be caused by the spectral sensitising dye. This emulsion is an emulsion of the core/shell type having a particular grain structure which has been chemically sensitised by means of thiourea compounds and a gold (I) compound which does not contain a labile sulphur atom. The emulsions of the present invention make it possible to reduce the dye desensitisation.
