Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a silver halide color photographic light-sensitive material. This invention relates to a silver halide color photographic light-sensitive material containing a 5-virazolone type magenta dye-forming coupler having an improved leaving group bonded to the active position via a specific high-boiling point organic solvent in a state of being dissolved and dispersed.

(Prior Art) A 5-pyrazolone coupler is generally used as a magenta coupler to form a magenta image in a subtractive color method. However, this 5-pyrazolone coupler causes a side reaction in the coupling reaction with the oxidation product of the developing agent, resulting in a low conversion rate to dye. When stored in a humid environment, there were problems such as fading or discoloration of the color image, and even discoloration of the white background. In order to improve these problems, as couplers, for example, U.S. Patent No. 4,351°897, U.S. Pat.
As disclosed in No. 1, a method of introducing a leaving group into the active position of a 5-pyrazolone coupler has been used, and although this has been improved, it cannot be said to be sufficient.

Recently, International Publication Patent No. WO 38104795 has been published as a coupler that has been improved in several ways, including the above-mentioned problems. It has been disclosed that improvements such as improved light fastness can be achieved.

However, in order to carry out rapid processing with a processing solution that does not contain benzyl alcohol in the color developing solution, it is desirable to further improve color development, and it is necessary for C to have no processing fluctuations in continuous processing.

In addition, it is desirable that there be no fluctuation in photographic performance during the period from when the photosensitive material is manufactured until it is used for printing as a print material, but this is not satisfied, and a technology that can fundamentally solve the problem has been found. Not yet. Moreover, it cannot be inferred from the above-mentioned disclosed technology.

(Problems to be Solved by the Invention) Therefore, the first object of the present invention is to provide a silver halide color photographic light-sensitive material that can obtain high color development in a limited development processing time. A second object of the present invention is to provide a silver halide color photographic material that exhibits little processing variation during continuous processing. A third object of the present invention is to provide a silver halide color photographic light-sensitive material which has improved storage stability over time.

Usually, the magenta coupler of the present invention is dissolved and used by mixing with a silver halide emulsion, but when dissolving the coupler, a known low-boiling organic solvent can also be used as an auxiliary solvent for dissolving the coupler.

In the color light-sensitive material of the present invention, a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer are coated on the support at this time or in an arbitrary arrangement thereof. is preferable.

Examples of the silver halide used in the present invention include silver chloride, silver bromide, silver chloride (iodo)bromide, and silver iodobromide.
Among these, silver chloride and silver chloride(iod)bromide are preferred. Furthermore, the halogen composition of the silver halide grains in one emulsion layer is such that 90 moles or more of the total silver halide constituting the silver halide grains is silver chloride, and salts containing substantially no silver iodide are used. Preferably, it consists of silver bromide. Here, the term "substantially free of silver iodide" means that the silver iodide content is below tO molar ratio. A particularly preferred halogen composition of the silver halide grains is silver chlorobromide containing substantially no silver iodide, in which 95 or more molar proportion of all the silver halide constituting the silver halide grains is silver chloride. .

Further, the silver halide grains according to the present invention can be reacted in a simultaneous mixing method of at least 10 moles of silver bromide to form a localized phase. Furthermore, the localized phase can also be formed using a so-called conversion method, which involves converting already formed silver halide into silver halide having a smaller solubility product. Alternatively, a localized phase can also be formed by adding silver bromide fine particles and recrystallizing them on the surface of silver chloride particles.

Regarding these manufacturing methods, for example, the above-mentioned patent application 1986-5
It is described in the specification of No. 19741.

In the localized phase of the silver halide grains of the present invention or its substrate,

The localized phase mainly contains iridium ions, rhodium ions, iron ions, etc., and the substrates mainly contain onumium, iridium, rhodium, platinum, ruthenium, palladium, etc.
Metal ions selected from cobalt, nickel, and iron sudo or complex ions thereof can be used in combination. Furthermore, the type and concentration of metal ions can be changed between the localized phase and the substrate.

In order to incorporate metal ions into the localized phase and/or other grain parts (substrate) of silver halide grains, the metal ions are added to the preparation solution before grain formation, during grain formation, or during physical ripening. do it. For example, metal ions can be added to a gelatin aqueous solution, a halide aqueous solution, a silver salt aqueous solution,
Alternatively, it can be added to other aqueous solutions to form silver halide grains. Alternatively, metal ions may be introduced in advance by incorporating metal ions into fine silver halide grains, adding these to a desired silver halide emulsion, and further dissolving the fine silver halide grains. This method is particularly effective for introducing metal ions into the localized silver bromide phase on the surface of silver halide grains. - The addition method can be changed as appropriate depending on where the metal ions are present in the silver halide grains. In particular, it is preferred that the localized phase is deposited with at least 50% of the total iridium added during the preparation of the silver halide grains.

Here, depositing the localized phase together with iridium ions means supplying an iridium compound simultaneously with, immediately before, or immediately after supplying silver and/or halogen to form the localized phase. say.

The purpose of these compounds can be achieved by co-emulsifying them with the couplers and adding them to the photosensitive layer, usually in an amount of 5 to 100 weight percent relative to the corresponding color coupler. In order to prevent the cyan dye image from deteriorating due to heat and especially light, it is more effective to introduce an external ray absorber into the layers on both sides adjacent to the cyan coloring layer.

Among the above antifading agents, spiroindanes, hindered amines, and the like are particularly preferred.

In the present invention, it is preferred to use the following compounds together with the above-mentioned couplers, especially with the pyrazoloazole couplers.

That is, a compound (CF) that chemically bonds with the aromatic amine developing agent remaining after color development processing to produce a chemically inert and substantially colorless compound and/or an aromatic compound remaining after color development processing. The use of a compound (CG) which chemically combines with the oxidized form of an amine-based color developing agent to form a chemically inert and substantially colorless compound may be used simultaneously or singly, for example, in the film during storage after processing. This is preferable in order to prevent staining and other side effects caused by the formation of coloring dyes due to the reaction between the remaining color developing agent or its oxidized product and the coupler.

A preferred compound (F) has a second-order reaction rate constant with p-anisidine of 2 (in trioctylhonupate at 80°C) t OL / mob sea ~ 1 × 1 O
It is a compound that reacts in the range of -st/rno1·θec.

If k2 is larger than this range, the compound itself may be unstable and may react with gelatin or water and decompose. On the other hand, if k2 is smaller than this range, the reaction with the remaining aromatic amine developing agent will be slow, and as a result, it may not be possible to prevent the side effects of the remaining aromatic amine developing agent, which is the objective of the present invention. .

A more preferable compound (F) can be represented by the following general formula (IPI) or (FIG).

General formula (Fl) R1-(A)n-X General formula (Fn) R2-C-Y In the formula, R1 and R2 each represent an aliphatic group, an aromatic group, or a heterocyclic group. n represents 1 or 0. B represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, an acyl group, or a sulfonyl group, and Y promotes the addition of an aromatic amine developing agent to the compound of general formula (Fn). represents a group that

Here, R1, X%Y, and R2 or B may be bonded to each other to form a cyclic structure.

Among the methods of chemically bonding with the residual aromatic amine developing agent, the typical ones are substitution reaction and addition reaction.

For example, benzotriazole compounds substituted with aryl groups (such as those described in US Pat. No. 4,553.794), 4-thiazolidone compounds (such as those described in US Pat. Nos. 3.31iL794 and 352.681), benzophenone compounds (for example, those described in JP-A No. 46-2784), silicon acid ester compounds (gAU, as described in US Pat. No. 4,705.

The photosensitive material produced according to the present invention may contain a water-soluble dye in the hydrophilic colloid layer as a filter dye or for various purposes such as preventing irradiation. Such dyes include okidinol dyes, hemioxonol dyes, styryl dyes, merocyanine dyes, cyanine dyes and azo dyes. Among them, okidinol dyes, hemioxonol dyes and merocyanine dyes are useful.

As the binder or protective colloid that can be used in the emulsion layer of the light-sensitive material of the present invention, it is advantageous to use gelatin, but other hydrophilic colloids can also be used alone or together with gelatin.

In the present invention, the gelatin may be either lime-treated or acid-treated. For more information on how to make gelatin, see Arthur Vuis, The Macromolecular Chemistry of Gelatin (Academic Press).

(published in 1964).

As the support used in the present invention, transparent films such as cellulose nitrace film and polyethylene terephthalate, which are usually used in photographic materials, and reflective supports can be used. For the purposes of the present invention, the use of reflective supports is more preferred.

The "reflective support" used in the present invention is one that enhances the reflectivity and makes the dye image formed in the silver halide emulsion layer clearer. Includes products coated with a hydrophobic resin containing a dispersed light-reflecting substance such as titanium oxide, zinc oxide, calcium carbonate, and calcium sulfate, and those using a hydrophobic resin containing a dispersed light-reflecting substance as a support. . For example, baryta paper, polyethylene-coated paper, polypropylene synthetic paper, transparent supports with a reflective layer or a reflective material such as glass plates, polyethylene terephthalate), cellulose triacetate, cellulose nitrate, etc. polyester film, polyamide film, polycarbonate film,
Examples include borinutylene film and vinyl chloride resin, and these supports can be appropriately selected depending on the purpose of use.

As a light-reflecting substance, white pigments in the presence of a surfactant can be

It is preferable to use one treated with ~tetrahydric alcohol.

The occupied area ratio (%) of white pigment fine particles (per defined unit area) is most typically calculated by dividing the observed area t into adjoining unit areas of 6 μm x 6 μm, and dividing the fine particles projected onto that unit area. It can be obtained by measuring the occupied WJ product ratio (%) (R1)k. The coefficient of variation of the occupied area ratio (%) can be determined by the ratio s/R of the standard deviation of R1 to the average value (R) of R1. The number (n) of target unit areas is preferably 6 or more. Therefore, the coefficient of variation 8/tile can be obtained.

In the present invention, the coefficient of variation of the occupied area ratio (%) of the pigment fine particles is preferably 115 or less, particularly α12 or less.

If it is 11.08 or less, the dispersibility of the particles can be said to be "substantially uniform."

The color photographic light-sensitive material of the present invention includes color development, bleach-fixing,
Preferably, a water washing treatment (or stabilization treatment) is performed. Bleaching and fixing may be carried out separately rather than in one bath as described above.

In the case of continuous processing, it is desirable that the amount of replenishment of the developer is small from the viewpoint of resource saving and low pollution.

The preferred replenishment amount of color developer is 8 equivalents for 1 m of light-sensitive material.
200- or less. More preferably, it is 120 or less. More preferably, it is 100 or less. However, the replenishment amount here refers to the amount at which a so-called color developer replenisher is replenished, and the amount of additives and the like for correcting aging deterioration and concentration is not included in the replenishment amount. Note that the additives mentioned here include, for example, water for diluting the concentrate, preservatives that tend to deteriorate over time, and alkaline agents that increase pH.

The color developing solution applied to the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine color developing agent as a main component. Although amine phenol compounds are also useful as the color developing agent, p-fuynylene diamine compounds are preferably used, and a typical example thereof is 3-
Methyl-4-amino-N,N-diethylaniline, 6-
Methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 5-

-Toluenesulfonate and the like. Two or more of these compounds can be used in combination depending on the purpose.

The color developer may contain pH buffering agents such as alkali metal carbonates, borates or phosphates, bromide salts, iodide salts,
Development inhibitors or antifoggants such as benzimidazoles, benzothiazoles or mercapto compounds are generally included. In addition, if necessary, hydroxylamine, diethylhydroxylamine, sulfite hydrazines, phenyl semicarbazides, triethanolamine, catechol sulfonic acids, triethylenediami/(I,4-diazabicycloC2,2,2]octane) Various preservatives such as ethylene glycol, organic solvents such as diethylene glycol, development accelerators such as benzyl alcohol, polyethylene glycol, quaternary ammonium salts, amines, dye-forming couplers, competitive couplers, sodium boron hydride, etc. Fogging agents, auxiliary developing agents such as 1-phenyl-3-pyrazolidone, viscosity imparting agents, various chelating agents such as aminopolycarboxylic acids, aminopolyphospho/acids, alkylhonufonic acids, and phosphonocarboxylic acids. , for example, ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethylimidinoacetic acid, 1-hydroxyethylidene-pre-1-diphosphonic acid, nitrilo-N,N,N-)rimetherenephosphonic acid. acid, ethylenediamine-N, N, N',
Representative examples include 14'-tetramethylenephosphonic acid, ethylene glycol (0-hydroxyphenylacetic acid), and salts thereof.

Further, when performing reversal processing, black and white development is usually performed and then color development is performed. This black and white developer contains known black and white developing agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as 1-phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol. It can be used alone or in combination.

The pH of these color developing solutions and black and white developing solutions is generally 9 to 12. Although the amount of replenishment of these developing solutions depends on the color photographic light-sensitive material being processed, it is generally less than υ3 per square meter of light-sensitive material, and is used to reduce the concentration of beautifying substance ions in the replenisher. Yo J500
It can also be lower than Wt. When reducing the amount of replenishment, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the contact area of the treatment layer with the air. It is also possible to reduce the replenishment (tt) by using means for suppressing the accumulation of bromide ions in the developer.

After color development, the photographic emulsion layer is usually bleached.

The bleaching process may be carried out simultaneously with the fixing process (white fixing process) or separately. Furthermore, in order to speed up the processing, a processing method may be used in which bleaching is followed by bleach-fixing. Furthermore, treatment in two continuous bleach constant baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment can be carried out as desired depending on the purpose. Examples of bleaching agents include iron (III) and cobalt (
III), compounds of polyvalent metals such as chromium (N), copper (II), peracids, quinones, nitro compounds, etc. are used.

Typical bleaching agents include ferricyanide; dichromate; organic complex salts of iron (ff[) or copal) (I), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, and t3-diaminoacetic acid. Aminopolycarboxylic acids such as propanetetraacetic acid, glycol ether diamine tetraacetic acid, or complex salts of citric acid, tartaric acid, malic acid, etc.; persulfates; bromates; perma/gannates; nitrobenzeas, etc. can be used. can. Among these, aminopolycarboxylic acid iron (II) complex salts and persulfates, including iron (Ill) complex salt of ethylenediaminetetraacetate, are preferable from the viewpoint of rapid processing and prevention of environmental pollution. Furthermore, aminopolycarboxylic acid iron(III) complexes are particularly useful in both bleach and bleach-fix solutions. The pI of the bleach solution or bleach-fix solution using these aminopolycarboxylic acid iron (ffi) complex salts
Although i is usually &5 to 8, it is also possible to process at an even lower pH for speeding up the process.

A bleach accelerator may be used in the bleaching solution, bleach-fixing solution, and their prebaths, if necessary.

In particular, ammonium thiosulfate salts are most widely used.

As the preservative for the bleach-fix solution, sulfites, bisulfites, or carbonyl bisulfite adducts are preferred.

The silver halide color photographic light-sensitive material of the present invention is generally subjected to water washing and/or stabilization steps after desilvering treatment.

The amount of water used in the washing process depends on the characteristics of the photosensitive material (for example, depending on the material used, such as a fogger), the application, the temperature of the washing water, the number of washing stages, the replenishment method such as countercurrent flow, jet flow, etc., and various other factors. It can be set over a wide range depending on the conditions. Among these, the relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is

According to the multi-stage countercurrent method described in the above-mentioned literature, the amount of water used for washing can be significantly reduced, but due to the increase in the residence time of water in the tank, bacteria will breed, and the generated suspended matter will adhere to the photosensitive material. The problem arises. In the processing of the color photosensitive material of the present invention, as a solution to such problems,
The method for reducing calcium ions and magnesium ions described in Japanese Patent Application No. 61-131, 652 can be used very effectively. In addition, chlorine-based disinfectants such as inthiazolone compounds and thiabendazole compounds, chlorinated sodium incyanurate, and other benzotriazoles described in JP-A No. 57-542, "Chemistry of Disinfectant and Antifungal Agents" by Hiroshi Horiguchi, Hygiene It is also possible to use the disinfectants described in Technical Gold Wire's ``Sterilization, sterilization, and anti-mildew technology of microorganisms'' and Japan Antibacterial and Antifungal Science Golden Wire's ``Encyclopedia of Antibacterial and Antifungal Agents.''

The pH of the washing water in the processing of the photosensitive material of the present invention is 4-
9, preferably 5-9. Washing water temperature, washing time, etc. can be set in various ways depending on the characteristics of the photosensitive material, usage, etc., but in general, it is 20 seconds to 10 minutes at 15-45°C, preferably 20 minutes.
A range of 30 seconds to 5 minutes at 5-40°C is selected. Furthermore,

Samples for sensitometry were processed as described in Example 1 before and after the start of continuous processing and the photographic performance of the resulting magenta color images was evaluated. The results are shown in Table 2.

(Continued) The numerical values shown indicate the difference between before and after continuous processing started. Large numbers indicate large fluctuations.

From Table 2, it was observed that the combination of the coupler of the present invention and the high boiling point organic solvent of the present invention enabled stable processing with little fluctuation in continuous processing.

It was also observed that, similar to the results obtained in Example 1, the sample using the coupler of the present invention in combination with the high boiling point organic solvent of the present invention had a high Dma3C and high sensitivity.

Example Row 5 The raw storage properties of the samples prepared in Example 1 were evaluated under the conditions listed in Table 3. Exposure and color development processing is carried out in row 1.
It was carried out according to the method described in .

We evaluated the change in sensitivity of the obtained magenta color image, but
The numbers shown represent the difference between the sensitivities obtained after the live storage conditions listed in Table 3 and the sensitivities obtained from samples stored at 5° C. for the same period. The larger the number, the greater the change in sensitivity and the worse the raw storage stability. The color development process was performed on all samples at the same time.Table 5 shows that the combination of the coupler of the present invention and the high boiling point organic solvent of the present invention was performed under high temperature and low humidity conditions and at low temperature and high humidity compared to the comparative sample. It is clear that under both conditions, the raw storage stability of the photosensitive material is stable at any temperature, showing excellent performance with little fluctuation.

It is clear that n is low, giving a high Dmaz, and exhibiting high sensitivity and excellent coloring ability. In particular, a low Dmin is advantageous for reflective materials in that they provide higher image quality.

In addition, when we evaluated the performance of raw storage stability shown in Sample Example 6 above, we found that comparative sample 61 had a change in butterfly sensitivity under both conditions [L04, but samples 62 to 67 using the coupler of the present invention Then, it is a variation in the range of 0 to CL02,
It was clear that it exhibited excellent raw storage stability.
