Abstract: This invention concerns a new processing solution to accelerate the bleaching of a color photographic product. This invention further concerns a method for the processing of a photographic product that uses such a solution to accelerate the bleaching process. The invention makes available a new solution to accelerate bleaching with improved efficacy.

Abstract: The invention relates to an aqueous concentrated solution of a photographic antifoggant. This antifoggant is 3-nitrobenzene sulfonate of sodium, and the solution contains between about 50 and 150 g/l of this antifoggant.

Abstract: This invention concerns a kit for the development of color photographic products. The kit comprises a basic solution containing an antifogging agent, and a second solution containing a color developing agent. This kit allows an easier preparation of the developer and of replenishment solutions of the developer.

Abstract: An aqueous solution for developing a silver halide photographic product comprises an alkanolamine in an amount greater than or equal to 0.6 mol/l, at least one wetting agent that is stable at a high pH and miscible in said developing solution, a developing agent capable of reducing the silver ions, and a quaternary ammonium salt having the following formula wherein R1, R2, R3 and R4 are independently hydrogen, an alkyl group of 1 to 4 carbon atoms, an aromatic carbocyclic group or heterocyclic group that can contain one or more nitrogen atoms, or R1 and R2 together, or R1, R2 and R3 together represent the atoms or bonds necessary for forming a ring with the nitrogen atom, having 5 or 6 atoms in the ring, and X is an anion.

Abstract: This invention relates to a 3-part kit preparing for a photographic developing bath for the processing of color photographic materials. The kit of this invention affords an efficient ready-to-use developing solution.

Abstract: The present invention concerns a radiographic product which makes it possible to obtain an image with no residual yellow coloring. The radiographic product comprises at least one photosensitive silver halide tabular grain emulsion spectrally sensitized with a spectral sensitizing dye in the blue region having an emission peak between 400 and 500 nm, and an optical brightener derived from 4,4'-diaminostilbene disulfonic acid having at least three anionic sulfo groups, put in the photosensitive layer of the radiographic products or in at least one layer situated between the photo-sensitive layer and the support. The radiographic product is applicable to radiographic systems including one or two intensifying screens.

Abstract: The present invention concerns a novel method for developing silver halide photographic products. This method involves processing photographic products that have an incorporated developing agent, and a nucleation agent, by surface application of an activator solution. This method intended for processing graphic arts films having high contrast.
