Abstract: A silver halide photographic photosensitive element having a hydrophilic colloidal layer prepared by dispersing photographic additives in a fatty oil which is liquid at room temperature; which boils at temperatures higher than 250.degree.C under atmospheric pressure; which is soluble in water in a proportion of less than about 10% by weight at 25.degree.C; and which dissolves water in a proportion of less than about 5% by weight at 25.degree.C, and a developing method thereof.

Abstract: A color photographic material having differently sensitized silver halide emulsion layers including a silver halide emulsion layer containing a 3-anilino-5-pyrazolone magenta dye-forming coupler, the coupler having a halogen atom or an alkoxyl group at the 2-position of the anilino group and an aliphatic acylamino group at the 5-position of the anilino 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: Color photographic elements containing silver halide and incorporated color-forming materials are described. These elements contain at least two differentially light-sensitive emulsion layers, the overlying layer being sensitive to the relatively shorter wavelengths and containing at least one yellow dye-forming color coupler which has the unusual ability to inhibit the reaction of competing couplers (such as citrazinic acid, for example) when competing couplers are used in color developing solutions in the conventional manner. Use of these couplers in the overlying (color) layer of multi-layer color photographic elements makes it possible to produce colored images having improved graininess.Couplers having this unusual capability are selected from those having the structures: ##SPC1##Wherein R.sub.1, R.sub.2 and R.sub.3 are as defined herein.

Abstract: A color photographic silver halide light-sensitive material which comprises a support having thereon at least two light-sensitive layers, at least one of said layers containing a compound capable of coupling with an oxidation product of a color developing agent and in which splitable hetero aromatic ring containing a triazole or diazole ring is connected to the carbon atom in the coupling position, through the nitrogen atom in the 1-position of said triazole or diazole ring.

Abstract: A multi-layer photosensitive material for color photography comprising a support and coated thereon, a first color image-forming layer unit composed of a red-sensitive silver halide emulsion, a second color image-forming layer unit composed of a green-sensitive silver halide emulsion and a third color image-forming layer unit composed of a blur-sensitive silver halide emulsion; characterized in that at least one of said color image-forming layer units has a composite layer structure including a lower layer and an upper layer which are positioned in sequence from the support, said upper layer has a higher sensitivity and a lower maximum developed color density than said lower layer, and at least one of said upper layer and lower layer contains a mercaptan type development inhibitor-releasing compound capable of reacting with an oxidation product of a primary aromatic amine to form a substantially colorless compound.

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.
