Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material containing a color stain inhibitor to prevent color stains. be.

[Background of the invention]

When a multilayer color photographic material containing a color-forming coupler in a silver halide photographic emulsion is developed using a color developing agent such as rose phenylene diamine, the color developing agent oxide produced during development forms an adjacent image. It is well known that the phenomenon of so-called "color turbidity" (color mixing) occurs, in which undesirable pigments are formed by migration into the forming layer. Furthermore, it is known that an undesirable "color fog" phenomenon occurs due to oxidation of the developing agent, fog of the emulsion, etc. during color development. In the following, this "color turbidity" and "color fog" will be collectively referred to as "color contamination."

Conventionally, various methods using hydroquinone have been proposed in order to prevent color staining. For example, regarding the use of monolinear alkylhydroquinone, U.S. Pat.
No. 728,657, JP-A-47-106329, etc., and the use of mono-branched alkylhydroquinone is described in U.S. Pat. -156483 and No. 49-106.329.

Furthermore, the use of sulponamide phenols as a color stain preventive agent is disclosed in JP-A-59-5247 and JP-A-59192.
No. 246, No. 59-222,836, etc.

In recent years, in the field of manufacturing technology for color photographic materials, in order to obtain even higher quality color photographs, it is possible to more effectively prevent color contamination and improve sharpness without reducing photographic sensitivity. There is a strong desire to develop a new color stain preventive agent that can be added to thin-layered photosensitive materials and that does not cause any change in performance even after long-term storage. However, none of the above-mentioned conventional color stain inhibitors could meet this new demand.

[Objective of the Invention] The object of the present invention is to further prevent color staining without reducing photographic sensitivity, to be able to be added to thin-layered photosensitive materials, and to prevent changes in performance even after long-term storage. An object of the present invention is to provide a silver halide color photographic material containing a color stain preventive agent that does not cause any damage.

The compound according to the present invention can be contained in an appropriate photographic constituent layer as desired; for example, it can be added as a color antifoggant to an emulsion layer containing a photographic coupler and a photosensitive silver halide at the same time. It can also be added to an intermediate layer installed between emulsion layers as a color turbidity preventive agent.

When the compound according to the present invention is used as a color antifoggant in an emulsion layer, 1.0 x 10 -' to 1.0 x 10 -' per layer. OX
It is preferably used at 10-6 mol/po, and when used in the intermediate layer as a color turbidity preventive agent, 1.0×1 per layer.
It is preferable to use a mold size of 0-3 to 1.0 x 10-5, but it is not limited thereto. Furthermore, it can be added to both the intermediate layer and the emulsion layer to prevent color fog and color turbidity.

The silver halide color photographic light-sensitive material of the present invention can be, for example, a color negative or positive film, and
It can be color photographic paper or the like.

The silver halide color photographic materials of the present invention, including these color photographic papers, may be for monochromatic use or for multicolor use. In the case of a multicolor silver halide photographic light-sensitive material, in order to perform subtractive color reproduction, a silver halide emulsion layer containing magenta, yellow and cyan couplers as photographic couplers and a non-light-sensitive silver halide emulsion layer are usually preferably used. Although it has a structure in which layers are laminated on a support in an appropriate number and order of layers, the number and order of layers may be changed as appropriate depending on the important performance and the purpose of use.

The silver halide emulsion used in the silver halide photographic light-sensitive material of the present invention includes conventional halides such as silver bromide, silver iodobromide, silver iodochloride, silver chlorobromide, and silver chloride. Any used in silver emulsions can be used.

The silver halide grains used in the silver halide emulsion may be obtained by any one of the acid method, neutral method, and ammonia method. The particles may be grown all at once, or may be grown after seed particles are created. The method of creating and growing the seed particles may be the same or different.

In the silver halide emulsion, halide ions and silver ions may be mixed simultaneously, or one may be mixed in the presence of the other. In addition, while considering the critical growth rate of silver halide crystals, we added halide ions and silver ions to
Growth may be performed by controlling and sequentially adding H and PAg simultaneously. Conversion methods may be used to change the silver halide composition of the grains after growth.

By using a silver halide solvent as necessary during the production of a silver halide emulsion, the grain size, grain shape, grain size distribution, and grain growth rate of silver halide grains can be controlled.

The silver halide grains used in silver halide emulsions are formed with cadmium salts, zinc salts, lead salts, chlorine salts, iridium salts or complex salts, rhodium salts or complex salts, iron salts, etc. during the grain formation and/or growth process. Alternatively, metal ions can be added to the inside of the particles and/or on the surface of the particles using complex salts, and reduction-sensitized nuclei can be added to the inside of the particles and/or on the surface of the particles by placing them in an appropriate reducing atmosphere. can.

Unnecessary soluble salts may be removed from the silver halide emulsion after the growth of silver halide grains is completed, or the salts may be left in the silver halide emulsion. In the case of removing the salts, it can be carried out based on the method described in Research Disclosure No. 17643.

The silver halide grains used in the silver halide emulsion may consist of uniform layers inside and on the surface, or may consist of different layers.

The silver halide grains used in the silver halide emulsion of the present invention may be grains in which a latent image is mainly formed on the surface, or grains in which a latent image is mainly formed inside the grains.

The silver halide grains used in the silver halide emulsion may have a regular crystal shape or may have an irregular crystal shape such as a spherical shape or a plate shape. In these particles, any ratio of (1001 planes to (1111 planes) can be used. Furthermore, particles having a composite form of these crystal forms may be used, or particles of various crystal forms may be mixed.

The silver halide emulsion used may be a mixture of two or more separately formed silver halide emulsions.

Silver halide emulsions can be chemically sensitized by conventional methods. In this case, sulfur-containing compounds that can react with silver ions, sulfur sensitization using activated gelatin, selenium sensitization using selenium compounds, reduction sensitization using reducing substances, and noble metals using gold or other noble metal compounds. Sensitization methods and the like can be used alone or in combination.

The silver halide emulsion used in the present invention can be optically sensitized to a desired wavelength range using a dye known as a sensitizing dye in the photographic industry. The sensitizing dyes may be used alone or in combination of two or more. Along with the sensitizing dye, the emulsion contains a dye that itself does not have a spectral sensitizing effect, or a supersensitizer, which is a compound that does not substantially absorb visible light and enhances the sensitizing effect of the sensitizing dye. Good too.

The silver halide emulsion used in the present invention may be used during chemical ripening and/or to prevent fog during the manufacturing process, storage, or photographic processing of light-sensitive materials, and/or to maintain stable photographic performance. At the end of ripening and/or after chemical ripening and before coating the silver halide emulsion, compounds known in the photographic industry as antifoggants or stabilizers can be added.

Binder (or protective colloid) for silver halide emulsions
It is advantageous to use gelatin, but other synthetic materials such as gelatin derivatives, graft polymers of gelatin and other polymers, proteins, '11N8) b conductors, cellulose derivatives, single or copolymers, etc. Hydrophilic colloids such as hydrophilic polymeric substances can also be used.

The photographic emulsion layer and other hydrophilic colloid layers of the silver halide photographic light-sensitive material of the present invention can be hardened by crosslinking binder (or protective colloid) molecules and using a hardening agent alone or in combination to increase film strength. can do. It is desirable to add the hardening agent in an amount that can harden the photosensitive material to such an extent that it is not necessary to add the hardening agent to the processing solution, but it is also possible to add the hardening agent to the processing solution.

A plasticizer can be added to the silver halide emulsion layer and/or other hydrophilic colloid layer of the silver halide photographic material of the present invention for the purpose of increasing its flexibility.

Furthermore, a dispersion (latex) of a water-insoluble or sparingly soluble synthetic polymer can be included in the photographic emulsion layer or other hydrophilic colloid layer of the light-sensitive material for the purpose of improving dimensional stability.

The emulsion layer of the light-sensitive material of the present invention is usually subjected to a coupling reaction with an oxidized form of an aromatic primary amine developer (for example, p-phenylenediamine derivatives, aminophenol derivatives, etc.) during color development processing. A dye-forming coupler is used that acts to form a dye. The dye-forming couplers are usually chosen such that for each emulsion layer a dye is formed which absorbs light in the emulsion layer's sensitive spectrum - for boat fishing, a yellow dye is formed in the blue-sensitive emulsion layer. A magenta dye-forming coupler is used in the green-sensitive emulsion layer, and a cyan dye-forming coupler is used in the red-sensitive emulsion layer. However, depending on the purpose, silver halide color photographic materials may be produced using different combinations from the above.

It is desirable that these dye-forming couplers have a group called a ballast group in the molecule, which has a carbon number of 8 or more and makes the coupler non-diffusive. In addition, even if these dye-forming couplers are 4-equivalent, in which 4 molecules of silver ions need to be reduced in order to form 1 molecule of dye, only 2 molecules of the root ion need to be reduced. Either equivalence is acceptable. Dye-forming couplers can be combined with the oxidized form of a developing agent to produce development accelerators, bleach accelerators, developers, silver halide solvents, toning agents, hardeners, fogging agents, antifoggants, chemical sensitizers, Spectral sensitizers and compounds that release photographically useful fragments, such as desensitizers, can be included. Colored couplers that have a color correction effect on these dye-forming couplers, or D that releases development inhibitors during development to improve image sharpness and image graininess.
An IR coupler may also be used. In this case, it is preferable that the dye formed from the DIR coupler is of the same type as the dye formed from the dye-forming coupler used in the same emulsion layer, but if the color turbidity is not noticeable, a different type of dye may be used. It may also be one that forms a pigment. Instead of the DIR coupler, a DIR compound may be used which, when used with or in combination with the coupler, undergoes a coupling reaction with the oxidized form of the developing agent to produce a colorless compound and release a development inhibitor at the same time.

The DIR couplers and DIR compounds used include those with an inhibitor directly attached to the coupling position and those with an inhibitor attached to the coupling position.
It is bonded to the coupling position via a valence group, and the inhibitor is bonded in such a way that the inhibitor is released by an intramolecular nucleophilic reaction or an intramolecular electron transfer reaction at the base circle separated by the coupling reaction ( (referred to as timing DIR couplers and timing DIR compounds). Furthermore, inhibitors that can be dispersed after release and those that are not so dispersible can be used alone or in combination depending on the purpose. A colorless coupler that undergoes a coupling reaction with an oxidized aromatic primary amine developer, but does not form a dye, can also be used in combination with a dye-forming coupler.

As the yellow dye-forming coupler, known acylace 1-anilide couplers can be preferably used. Among these, hendiylacetanilide and pivaloylacetanilide compounds are advantageous. A specific example of a yellow coupler that can be used is British Patent No. 1,077.87.
