Silver halide colour photographic material

A process of forming a colour negative image comprises using a photographic material comprising a support having coated thereon a silver halide radiation-sensitive emulsion layer contg. silver bromide or silver chloride, a dye image-forming coupler, and a cpd. capable of releasing a development inhibitor an development with a primary amino colour developing agent, the process being performed in the presence of a linear polyester of a dicarboxylic acid, the polyester contg. intra-linear thioether atoms. Also claimed is a photographic material comprising: (i) a support having coated on it at least one silver halide radiation sensitive emulsion layer contg. silver bromide, or silver chloride; (ii) a dye image forming coupler; and (iii) a cpd. capable of releasing a development inhibitor upon exposure and development with a primary amino colour developing agent, and a linear polyester of a dicarboxylic acid, the acid contg. intra-linear thioether atoms. La présente invention concerne une produit au chlorure d'argent pour la photographie.Le produit selon l'invention comprend au moins une couche d'émulsion au chlorure d'argent associée à un coupleur DIR, et un polyester d'un diacide et d'un diol comprenant au moins un hétéroatome de soufre.On obtient une diminution du voile, sans perte de sensibilité.
