Abstract

PURPOSE:To prevent the fading of the latent image by adding monocarboxy substituted phenylmercaptan to a silver halide photographic emulsion which is chemically sensitized by a gold compound. CONSTITUTION:The monocarboxy substituted phenylmercaptan compound expressed by the general formula (I)[in the formula, R is a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an acyl group, an amino group, (a) is 1 or 2]is added to silver halide at 60mg-5,000mg per mol thereof. If the settling of silver halide crystal is carried out in the presence of said compound, said compound acts as a physical ripening supressing agent to form fine particles. This prevents the fading of the latent image but lowers sensitivity. If this adapted to an emulsion which is chemically sensitized by a gold compound, it increases the sensitivity and prevents the fading of the latent image. Althrough it is added in the stage after physical repening, it has the same effect.
