Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material with good color reproducibility. When forming an image, a cyan image with increased apparent color purity is obtained by removing a compound that emits fluorescence in the sub-absorption wavelength range of the unwanted yellow part of the color image, and a cyan image with no sub-absorption is obtained. The present invention relates to a silver halide color photographic material with extremely good color reproducibility, which is realized by using a magenta color image obtained from a highly pure pyrazoloazole magenta coupler.

(Prior Art) In silver halide color photographic light-sensitive materials, so-called dye-forming couplers (hereinafter simply referred to as couplers) react with a light-sensitive silver halide emulsion and an oxidized product of an aromatic-grade amine developer to form an azomethine dye. A method using a yellow coupler, a magenta coupler, and a cyan coupler is usually used.

The yellow couplers that have been mainly used in practice so far have been acylacetamide derivatives such as benzoylacetanilide and pivaloylacetanilide, the magenta couplers have been yoichi pyrazolone derivatives, and the cyan couplers have been phenol and naphthol derivatives. However, the azomethine dyes formed from these couplers have unnecessary sub-absorption compared to the absorption waveform that is considered ideal, and improvements have been desired in terms of color reproduction in color photographs.

Of these three color couplers! - Virazolone maze/tacoupler is most important for improving color reproducibility due to the high visibility of humans in this wavelength range, so research has been conducted to improve it for a long time, and its sub-absorption around ≠ 3 Qnm In order to improve tail breakage on the long wavelength side, the indashilon skeleton described in U.S. Patent No. 3°770, ≠≠7, and the British Patent No. 1.

Since the side absorption of the color image has not been improved, the effect of this improvement of the magenta coupler is diminished. Therefore, there has been a strong desire to improve cyan and yellow couplers, particularly cyan couplers.

Regarding cyan couplers, US Patent No. 772, /
Couplers described in No. Otsuko, European Patent Application Publication λt, and No. 4133 have been proposed, but the improvements are insufficient,
Further improvements were desired due to poor color image stability. Recently, a method for optically correcting side absorption by using a coupler that emits a fluorescent dye after coupling was disclosed in U.S. Pat. It describes the color correction effect in negative systems, and for color balancers (positive systems), it only teaches that this type of coupler is applied to the yeh j low coupler, -, and the color of the color peno ξ-. There is no equivalent suggestion to apply this cypress coupler to a cyan coupler to improve reproducibility.

(Problems to be Solved by the Invention) The present invention mainly improves the cyan color image whose hue has not been sufficiently improved, and combines it with an azomethy/magenta color image of a pyrazoloazole magenta coupler having a good hue to reproduce color. This was done with the aim of providing high-quality color photographs.

(Means for Solving the Problems) In order to achieve the above object, the present inventors conducted intensive studies and found that a compound (fluorescent whitening A cyan coupler (abbreviated as FBR) that releases cyan coupler in an image-wise manner.

1≠6− It is preferred to have less than 0 mol% silver bromide localized phase.

The arrangement of such a localized silver bromide phase can be freely determined depending on the purpose, and it may be located inside the silver halide grain, on the surface or subsurface, or divided into the interior and the surface or subsurface. You can leave it there. Further, the localized phase may have a layered structure surrounding the silver halide grains inside or on the surface, or may have a discontinuously isolated structure. One preferred example of the arrangement of localized silver bromide phases is a localized phase with a silver bromide content of at least 10 mol%, more preferably more than 20 mol%, on the surface of silver halide grains (particularly at the corners of the grains). The existing phase is locally epitaxially grown.

It is preferable that the silver bromide content of the localized phase exceeds 20 mol%; however, if the silver bromide content is too high, it may cause desensitization when pressure is applied to the photosensitive material, or the composition of the processing solution may be affected. Fluctuations may impart unfavorable characteristics to the photographic material, such as large changes in sensitivity and gradation.

Taking these points into consideration when determining the silver bromide content of the localized phase, the color photographic material of the present invention has a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer on a support. Preferably, the silver emulsion layers are applied in this order or in any arbitrary arrangement thereof.

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 90 mol% of the total silver halide constituting the silver halide grains.
The above is silver chloride, and preferably consists of silver chlorobromide containing substantially no silver iodide. Here, "substantially free of silver iodide" means that the silver iodide content is 1.0 mol% or less. A particularly preferred halogen composition of the silver halide grains is silver chlorobromide containing substantially no silver iodide, in which 95 mol % or more of the total silver halide constituting the silver halide grains is silver chloride.

Further, the silver halide grains according to the present invention have a silver bromide content of at least more than 10 mol %, and 20 to 6 mol %.
A range of 0 mol% is preferred, and a range of 30 to 50 mol% is most preferred. The other silver halide constituting the localized phase is preferably silver chloride. The silver bromide content of the localized phase is

The localized phase is preferably composed of 0.1 to 20% silver, more preferably 0.5 to 7% silver, based on the amount of gold and silver constituting the silver halide grains of the present invention. preferable.

The interface between such localized silver bromide phase and other phases may have a clear phase boundary or a short transition region where the halogen composition changes gradually. The position of the silver localized phase can be determined by observation using an electron microscope or by the method described in European Patent Application Publication No. 273430A2.

Various methods can be used to form such a localized silver bromide phase. For example, it is possible to form a localized phase by reacting a soluble silver salt and a soluble halogen salt using a one-sided mixing method or a simultaneous mixing method. 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. Or bromide iHk
A localized phase can also be formed by adding particles and recrystallizing them on the surface of silver chloride particles.

Regarding these manufacturing methods, for example, the above-mentioned European patent application 2
It is described in the specification of No. 73430A2.

In the localized phase of the silver halide grains of the present invention or its substrate,
The effect of the present invention is further improved by containing metal ions different from silver ions (e.g., metal ions from group Ⅰ of the periodic table, transition metal ions from group Ⅰ, lead ions, thallium ions) or complex ions thereof. It is preferable.

It is mainly effective for introducing iridium ions and rhodium metal ions into the localized phase. The addition method can be changed as appropriate depending on where in the silver halide grains the metal ions are to be present.

In particular, the localized phase is preferably deposited with at least 60% 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 silver halide grains according to the present invention have (100
) surface, (111) surface, or both surfaces, and even those containing higher-order surfaces are preferably used. 6 The shape of the silver halide grains used in the present invention is cubic,
Those with regular crystal shapes such as tetradecahedrons and octahedrons, as well as irregular crystal shapes such as spherical and plate shapes, are used mainly as substrates, such as mu ions and iron ions. Metal ions selected from osmium, iridium, rhodium, platinum, ruthenium, palladium, cobalt, nickel, iron, etc. or complex ions thereof can be used in combination. Further, the type and concentration of the second metal 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 (substrates) of silver halide grains, the metal ions are added to the conditioning solution before grain formation, during grain formation, or during physical ripening. Just add it. For example, metal ions in gelatin aqueous solution, halide aqueous solution, 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 applicable to silver bromide localized phases on the surface of silver halide grains, or to complexes of these crystal forms. It is also possible to use particles made of a mixture of particles with various crystal forms, but in particular, particles with the above-mentioned regular crystal forms in a proportion of 50% or more,
The content is preferably 70% or more, more preferably 90% or more. In the silver halide emulsion used in the present invention, tabular grains having an average aspect ratio (length/thickness ratio) of 5 or more, particularly preferably 8 or more, account for 50% of the total projected area of the grains.
% or more may be used.

The size of the silver halide grains related to the present invention may be within the range commonly used, but the average grain size is 0.1 μm to 1 μm.
．． Preferably, the thickness is 5 μm.

The particle size distribution may be polydisperse or monodisperse, but
Monodispersity is preferred. The particle size distribution, which indicates the degree of monodispersity, has a statistical coefficient of variation (value S/d obtained by dividing the standard deviation S by the diameter d when the projected area is approximated by a circle) of 2.
It is preferably 0% or less, and more preferably 15% or less.

Further, two or more of such tabular grain emulsions and monodispersed emulsions may be mixed. When emulsions are mixed, it is preferable that at least one of the emulsions has the above-mentioned variation coefficient, and it is more preferable that the variation coefficient of the mixed emulsion satisfies the above-mentioned range of values.

The so-called matrix portion other than the localized phase of the silver halide grain used in the present invention may have different phases inside and on the surface, or may consist of a uniform phase.

The silver halide emulsion used in the present invention is usually one that has been physically ripened, chemically ripened, and spectrally sensitized.

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 -7g'-oxonol dyes, hemioxonol dyes, styryl dyes, merocyanine dyes, cyanine dyes and azo dyes. Among them, oxonol 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 be used alone or together with gelatin.

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. It is preferable to use the material of the present invention whose surface has been treated with a dihydric to tetrahydric alcohol.

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

In the present invention, the coefficient of variation of the occupied area ratio (%) of the pigment fine particles is preferably 0.15 or less, particularly 0.12 or less. If it is 0.08 or less, it can be said that the dispersibility of the particles is substantially "uniform", and for this purpose, it is more preferable to use a reflective support.

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. Examples include those 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, polyester films such as polyethylene terephthalate, cellulose triacetate or cellulose nitrate, polyamide film, polycarbonate film,
There are polystyrene films, vinyl chloride resins, and the like, and these supports can be appropriately selected depending on the purpose of use.

As the light-reflecting substance, it is preferable to sufficiently knead a white pigment in the presence of a surfactant, and the color photographic material of the present invention can be prepared by color development, bleach-fixing, washing treatment (or stabilization treatment). It is preferable that the Bleaching and fixing may be carried out separately instead of 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 2 per 1 d of light-sensitive material.

The color developer may contain pH buffering agents such as alkali metal carbonates, borates or phosphates, bromide salts, iodide salts,
Contains development inhibitors or anti-capri agents such as benzimidazoles, benzothiazoles or mercapto compounds. Further, if necessary, representative examples include hydroxylamine, diethylhydroxylamine, sulfite hydrazines, phenyl semicarbazides, trieta, 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. The amount of replenishment of these developing solutions depends on the color photographic light-sensitive material to be processed, but it is generally less than 31 per square meter of the light-sensitive material, and by reducing the bromide ion concentration in the replenisher,
It is also possible to make Tn1 or less. 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. In addition, measures to suppress the accumulation of bromide ions in the developer solution include nolamine, catechol sulfonic acids, and triethylenediamine (1,4-diazabicyclo[2°2.2]octane) @

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

The bleaching process may be carried out simultaneously with the fixing process (bleach-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 with two consecutive bleach-fixing 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 (■) and cobalt (II).

Typical bleaching agents include ferricyanide; organic complex salts of monoiron dichromate (I[[) or cobalt (III), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3 -Aminopolycarboxylic acids such as diaminopropanetetraacetic acid and glycol ether diaminetetraacetic acid, or complex salts of citric acid, tartaric acid, malic acid, etc.;
Persulfates; bromates; permanganates; nitrobenzenes and the like can be used. Among these, aminopolycarboxylic acid iron(I[I) complex salts and persulfates, including ethylenediaminetetraacetic acid iron(III) complex salts, are preferable from the viewpoint of rapid processing and prevention of environmental pollution. Furthermore, aminopolycarboxylic acid iron(I[I) complex salts are particularly useful in both bleaching solutions and bleach-fixing solutions. The pH of bleaching solutions or bleach-fixing solutions using these aminopolycarboxylic acid iron(III) complexes is usually 5.5 to 8, but in order to speed up the processing, the pH can be lowered. .

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

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 materials used such as couplers), the application, the temperature of the washing water, the number of washing tanks (number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions.

Chlorinated disinfectants such as isothiazolone compounds, cyabendazole, chlorinated sodium isocyanurate, and other benzotriazoles listed in the issue, "Chemistry of antibacterial and fungicidal agents" by Hiroshi Horiguchi, Sanitary technology complete volume "Sterilization of microorganisms" It is also possible to use the disinfectants described in "Encyclopedia of Antibacterial and Antifungal Agents" edited by the Japanese Society 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. The washing water temperature and washing time can also be set variously depending on the characteristics of the photosensitive material, its use, etc., but generally 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, the photosensitive material of the present invention can also be directly processed with a stabilizing solution instead of washing with water. In such stabilization treatment, Japanese Patent Application Laid-Open No. 57-8.543, 58-14゜8
All known methods described in No. 34, No. 60-220.345 can be used.

Further, following the water washing treatment, a further stabilization treatment may be carried out, such as a stabilizing bath containing formalin and a surfactant, which is used as a final bath for color photographic materials for imaging. can.

Various chelating agents and antifungal agents can also be added to this stabilizing bath.

The various processing solutions used in the present invention are used at a temperature of 10°C to 50°C. Normally, the standard temperature is 33°C to 38°C,
It is possible to increase the temperature to accelerate the processing and shorten the processing time, or conversely to improve the image quality and stability of the processing solution by increasing the temperature to a lower temperature. In addition, West German Patent No. 2.226,770 or U.S. Patent No. 3.6 is used to save silver on photosensitive materials.
Treatment using cobalt intensification or hydrogen peroxide intensification as described in No. 74.499 may also be carried out.

In order to fully exhibit the excellent features of the silver halide photographic light-sensitive material of the present invention, it is necessary to use a color developing solution that is substantially free of benzyl alcohol and contains bromine ions of 0.002 molph 1 or less for 2 minutes and 30 minutes. It is preferable to process with a development time of seconds or less.

The above-mentioned "substantially free of benzyl alcohol" means less than 2 m of benzyl alcohol per 11 of the color developer, preferably 0.5 m! , hereinafter most preferably means not included at all.

One flow liquid can also be reused in other processes such as the desilvering process.

The silver halide color light-sensitive material of the present invention may contain a color developing agent for the purpose of simplifying and speeding up processing. In order to incorporate the color developing agent, it is preferable to use various precursors of the color developing agent. For example, U.S. Patent No. 3,342,59
Indoaniline compound described in No. 7, No. 3.342,
No. 599, Research Disclosure 14.850

, 719.492, JP-A-53-1
Examples include urethane compounds described in No. 35,628.

The silver halide color light-sensitive material of the present invention may contain various 1-phenyl-3-
Pyrazolidones may also be incorporated. Typical compounds are described in JP-A-56-64,339, JP-A-57-14,4547, and JP-A-58115.438.

Next, the present invention will be explained in detail based on examples.

(Example) Since it is not possible to evaluate the effects of the present invention by spectrum measurement using a normal measuring device, the evaluation was carried out as follows.

Spectral measurement method> The equipment used to measure the reflection spectrum (self-made) is shown in Figure 1. This device will be explained below.

A xenon lamp (manufactured by Ushio/jOVJ) that emits continuous light from ultraviolet to visible light is used as a light source, and a heat absorption filter (manufactured by Hoya Glass) is used to remove infrared rays that interfere with measurement.
1A-, tO type) Use two pieces to cut and cut.

White light from the light source is guided into the sample chamber by a quartz optical fiber and is incident on the sample surface at an angle of ≠50.

The reflected light including the wide reflection and/or specular reflection from the sample (the receiving angle is variable between θ° and ≠t') is
The light is received by a quartz fiber and then separated into spectra using a spectrometer (polychromator made by Jovan Voyage, focal length 200).

The separated light was detected using a multi-channel detector (manufactured by Hamamatsu Photonics, 102) using a photodiode array unit.
≠ channel) to simultaneously measure light in the range from 200 μm to 00 μm.

The output from the multichannel detector is sent to a data processing system, where it undergoes 72-bit analog-to-digital conversion and is then stored in the main memory of a 7-bit microcomputer (NEC PC-5i'tO/fJ). ,
Perform various data conversions to obtain spectra.

This measuring device uses a single beam optical system, so when measuring the spectrum, first measure uncolored paper (blank, the support is WP paper), and store this signal output as Io and λl. . Next, the color-developed sample ξ- is measured.The signal output from this sample is assumed to be .lambda.i and .lambda.i. The conversion from vector to vector was performed using the formula.

Through these series of operations and data processing, it is possible to accurately measure the spectrum of a color image formed by ejecting a fluorescent substance imagewise.

[Brief explanation of drawings]

FIG. 1 is a diagram of the apparatus used in measuring the reflection spectrum in the embodiment of this patent. Figure 1 compares the reflection spectra of comparative samples A and B prepared in Example/. In comparative sample B, the sub-absorption in the yellow part of the cyan image is considerably reduced, but the color reproduction effect is low due to the sub-absorption in the yellow part of the magenta image (see Figure μ). FIG. 3 compares the reflection spectra of comparative sample B prepared in Example 1 and samples (1-/) and (I-7) of the present invention. Comparative sample B had side absorption in the yellow part of the magenta image, but this was considerably reduced in the sample of the present invention. In addition to the decrease in sub-absorption in the yellow part of the cyan image area, color turbidity due to sub-absorption in the yellow part was improved and the color reproduction effect was increased (see Figure ≠). Figure ≠ is a U*■'' chromaticity diagram obtained by calculation to quantify changes in the color reproduction gamut.The larger the area, the better the color reproducibility.The sample of the present invention ( I-/
') clearly shows that the color reproducibility has improved. Patent applicant: Fuji Photo Film Co., Ltd.
