Abstract: A photographic material having a light-sensitive silver salt emulsion layer which layer contains a silver salt developer of the chroman series having the formula defined below.

Abstract: A process is described of improving the development characteristics of photographic silver halide elements by the use of compounds corresponding to the formula:RO(CH.sub.2 CH.sub.2 O).sub.n (CO).sub.m Awherein:R represents hydrogen, C.sub.1 -C.sub.5 alkyl or (--CO).sub.m --A,n is an integer of at least 4,m is 0 or 1, andA represents, when m is O, sulphoalkyl, carboxyalkyl, or sulphoalkoxycarbonylalkyl, and when m is 1, carboxyalkyl, sulphoalkoxycarbonylalkyl, carboxyalkenyl, sulphoalkoxycarbonylalkenyl, carboxyphenyl, sulphoalkoxycarbonylphenyl or sulphophenyl,The aliphatic hydrocarbon groups having at most 4C-atoms and the carboxyl and sulpho groups being in acid or salt form. The polyethylene glycol derivatives increase developability and sensitivity of black-and-white as well as colour emulsions. They also improve lith-development of photographic "lith"-emulsions.

Abstract: This invention relates to a development inhibitor-releasing compound of the following general formula: ##SPC1##Wherein Z is an atomic grouping necessary to form a carbocyclic ring; Y is a group which, when the sulfur atom of the thioether linkage is released, forms together with said sulfur atom a compound having a development-inhibiting action; and X is a hydroxyl group or a substituted or non-substituted amino group.

Abstract: A color photographic material comprising a support having coated thereon at least one silver halide emulsion layer containing a magenta dye forming coupler having a 3-anilino-5-pyrazolone ring in which the ortho position of the anilino group at the 3-position is substituted with a halogen atom, an alkyl group, an alkoxy group, an amide group, an aryl group, an aryloxy group, a cyano group, a nitro group, a hydroxyl group, or an amino group and having a hydrophobic residue of 8 to 32 carbon atoms, the silver halide emulsion layer or an emulsion layer adjacent to the silver halide emulsion layer containing a hydroquinone derivative having at least one substituent of at least 8 carbon atoms or a precursor capable of providing such a hydroquinone derivative by hydrolysis.The color photographic material provides magenta dye images having good color separation and less color fog and less color stains in the highlight areas.

Abstract: An improved photographic processing system and process are provided. The system includes a novel photographic recording medium comprising a layer of silver halide emulsion, a barrier layer disposed on a surface thereof, the barrier layer being soluble in aqueous alkali but insoluble in water and acidic media, and an acidic developer disposed as a layer on the outer surface of the barrier layer or mixed therewith. The developer is activatable at an alkaline pH. A novel processing web comprising a support containing an alkali and a free water source is also provided, which web is adapted for contacting the layer containing developer to initiate development of the silver halide. The developer thus is isolated from alkali and from the emulsion prior to developing. The process includes exposure of the recording medium, followed by the described contacting for development of a visible image.

Abstract: A light-sensitive member for use in a color diffusion transfer element which comprises a support having thereon at least one silver halide emulsion layer and at least one dye developing agent combined with the silver halide in the silver halide emulsion layer, wherein at least one layer on the support contains an auxiliary developing agent selected from the group consisting of a catechol having at least one substituent, with at least one of the substituents being selected from the group consisting of an alkoxy group, an acylamino group, an acylimino group, an alkylsulfonamido group, an alkylthio group, an arylthio group, an alkylseleno group, an arylseleno group and a heterocyclic group; dissolved in a substantially water-insoluble solvent and present in the layer as finely divided liquid droplets.

Abstract: A color photographic material having at least one silver halide emulsion layer containing a 3-anilino-5-pyrazolone type magenta dye forming coupler and a phenolic compound for improving the light fastness of the magenta dye formed by the coupling reaction of the magenta dye forming coupler with the oxidation product of a color developing agent in combination with a nucleus-substituted hydroquinone, in which the reduction of the coupling reactivity of the magenta dye forming coupler during the storage of the color photographic material caused by the presence of the phenolic compound is prevented efficiently.

Abstract: An incorporated-coupler type multi-layer color photographic sensitive material comprising a support and at least two photosensitive emulsion layers thereon which form images having a different color from each other on color development, wherein at least one of the photosensitive emulsion layers comprises two or more unit layers, with at least one of the unit layers containing a hydroquinone derivative. Interlayer color correction is obtained in the color photographic sensitive material.
