By this means, sensitization and high contrast are contrived and improvement of the color reproducibility and sharpness are attained.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a silver halide color photographic light-sensitive material, and particularly to a silver halide color photograph containing a yellow-colored cyan coupler and a selenium-sensitized emulsion layer. It relates to photosensitive materials.

(Prior Art) As a means for improving color reproducibility and sharpness, it is possible to use so-called DIR compounds described in, for example, JP-A-54-145135, JP-A-56114946, and JP-A-57-151.944. is well known.

It is true that these compounds have improved the interlayer effect and edge effect, and improved color reproducibility and sharpness to some extent, but if the released development inhibitor is not released in a sufficient amount to inhibit There are problems such as not being able to obtain the desired effect or edge effect, and not being able to obtain the desired glabellar effect unless the photosensitive layer to be suppressed is properly developed, and it is difficult to provide a sufficient effect in the entire n-light region. However, in order to obtain this effect, the sensitivity of the added color-sensitive layer and the adjacent color-sensitive layer was lowered.

On the other hand, it has been found that an effect similar to the interlayer effect from the red-sensitive emulsion layer to the blue-sensitive layer in terms of photographic performance can be obtained by using a yellow-colored cyan coupler in the red-sensitive emulsion layer. 1986-221748, Japanese Patent Application Publication No. 1-319144, and West German Patent Publication No. 381546

That is, the effect was not sufficient just by using these yellow colored cyan couplers. In addition, conventionally known yellow colored cyan couplers had problems such as the yellow dye having a small molecular extinction coefficient and low power and pulling activity.

On the other hand, silver halide emulsions used in silver halide photographic materials are usually chemically sensitized using various chemical substances in order to obtain desired sensitivity, gradation, etc. As typical methods, various sensitization methods are known, including sulfur sensitization, selenium sensitization, noble metal sensitization such as gold, reduction sensitization, and combinations thereof.

In addition, various improvements have been made to improve sensitivity and improve graininess.

Among the above sensitization methods, the selenium sensitization method is described in US Pat.

In general, selenium aggravation has a greater sensitizing effect than sulfur sensitization, which is commonly carried out in the industry, but has a higher fog. There was a problem that it was easy to soften the tone.

There was also a desire for higher frequencies.

(Illumination to be Solved by the Invention) An object of the present invention is to provide a photosensitive material with high sensitivity, high contrast, and excellent color reproducibility and sharpness.

(Means for solving problems) The object of the present invention has been achieved by the following photographic material.

In a silver halide color photographic light-sensitive material having at least one silver halide emulsion layer on a support, the silver halide grains contained in the emulsion layer contain a selenium sensitizer, a gold sensitizer, and a sulfur sensitizer. 1. A silver halide color photographic light-sensitive material, which is chemically sensitized with at least one of the following, and contains a yellow-colored cyan coupler in at least one layer.

The present invention will be explained in detail below.

The emulsions of the present invention are sensitized with at least one different sensitizer, each of a selenium sensitizer, a gold sensitizer, and a sulfur sensitizer.

Here, selenium sensitization is carried out by a conventionally known method. That is, this is usually carried out by adding an unstable selenium compound and/or a non-labile selenium compound and stirring the emulsion at a high temperature, preferably 40° C. or higher, for a certain period of time. Selenium sensitization using an unstable selenium sensitizer described in Japanese Patent Publication No. 44-15748 is preferably used. Specific unstable selenium sensitizers include aliphatic inselenocyanate 2-ates such as allyl isoselenocyanate,
These include selenoureas, selenoketones, selenoamides, selenocarboxylic acids and esters, and selenophosphates. Particularly preferred unstable selenium compounds are shown below.

■ Colloidal metallic selenium ■, organic selenium compounds (selenium atoms bonded 2M to the carbon atoms of organic compounds through covalent bonds) Cyanate b Selenoureas (including unol type) Examples include selenourea, and methyl, ethyl, propyl, isopropyl,
Aliphatic selenoureas such as butyl, hexyl, octyl, dioctyl, tetramethyl, N-(β-carboquinethyl)-N', N'-dimethyl, NN-dimethyl, diethyl, dimethyl; aromatic selenoureas such as phenyl, tolyl Aromatic selenoureas having one or more groups; Heterocyclic selenoureas having heterocyclic groups such as pyridyl and hendzthiaduryl. Particularly preferred selenoureas are tetramerized selenoureas. A specific example is shown below.

Triphenylphosphine selenide b Selenophosphates For example, thoriate, trilopyl selenophosphate Preferred types of unstable selenium compounds have been described above, but these are not intended to be limiting. Speaking of unstable selenium compounds as emulsion sensitizers, the structure of the compound is not very important as long as selenium is unstable; the organic part of the selenium sensitizer molecule carries selenium, It is generally understood that it has no role other than to be present in the emulsion in an unstable form.

In the present invention, unstable selenium compounds having such a broad concept are advantageously used.

Selenium sensitization using non-labile selenium sensitizers described in Japanese Patent Publication No. 46-4553, Japanese Patent Publication No. 52-34492, and Japanese Patent Publication No. 52-34491 is also used. Non-labile selenium compounds include, for example, selenite, potassium selenocyanide, selenazole, quaternary ammonium salts of selenazole, diarylselenide, diaryldiselenide, 2-p-)lylselenophosphthioselenazolidinedione, 2 - Selenoxolidine and derivatives thereof.

The non-unstable selenium sensitizer and thioselenazolidinedione compound described in Japanese Patent Publication No. 52-38408 is also effective.

These selenium sensitizers are dissolved in water or an organic solvent such as methanol or ethanol alone or in a mixed solvent and added at the time of chemical sensitization. It is preferably added before the start of chemical sensitization. The selenium sensitizer used is not limited to one type, but two or more of the above selenium sensitizers can be used in combination.

A combination of unstable selenium compounds and non-labile selenium compounds is preferred.

The amount of the selenium sensitizer used in the present invention varies depending on the activity of the selenium sensitizer used, the type and size of silver halide, the temperature γ and time of ripening, etc., but preferably 1
．． The amount is 1×10 −1 mole or more per mole of silver halide. More preferably, it is 1×10 −1 mol or more and 5×10 −′ mol or less. When a selenium sensitizer is used, the temperature for chemical ripening is preferably 45°C or higher. More preferably 5

The emulsion of the present invention is chemically sensitized using both sulfur sensitization and gold sensitization.

Sulfur sensitization usually involves adding a sulfur sensitizer to
This is preferably carried out by stirring the emulsion at 40°C or higher for a certain period of time.

Further, gold sensitization is usually carried out by adding a gold sensitizer and stirring the emulsion at a high temperature, preferably 40° C. or higher, for a certain period of time.

Sulfur sensitizers described in JP 5-45016 and the like can also be used. The amount of sulfur sensitizer added may be sufficient to effectively increase the sensitivity of the emulsion, and this amount may vary considerably under various conditions such as pH 1 temperature, silver halide grain size, etc. It varies over a range, but preferably 1X10-' moles or more and 5X10-' moles or less per mole of silver halide.

As the gold sensitizer for the above gold sensitization, the oxidation number of gold may be +1 or +3, and a gold compound commonly used as a gold sensitizer can be used.A typical example is chloroauric acid. salt, potassium chloroauric acid, auric trichloride, potassium auric thiocyanate, potassium iodo oleate, tetracyanoauric acid, ammonium aurothiocyanate, pyridyl trichlorogold, and the like.

The amount of gold sensitizer added varies depending on various conditions, but as a guideline, it is 1 x 10 to 5" moles or more per 1 mole of halogenated
It is preferably not more than X10-' mole.

During chemical ripening, there is no need to set any particular restrictions on the timing and order of silver halide cutting and addition of selenium sensitizers, sulfur sensitizers, gold sensitizers, etc.; for example, at the beginning of chemical ripening (preferably) Alternatively, the above compounds can be added simultaneously or at different times during the chemical ripening. In addition, the above compound may be dissolved in a single wave or a mixed solution of water or an organic solvent miscible with water, such as methanol, ethanol, acetone, etc., and then added.

The silver halide emulsion of the present invention is preferably reduction sensitized during the grain formation process.

Applying reduction sensitization during the grain formation process of a silver halide emulsion basically means performing it during nucleation, ripening, and growth. Reduction sensitization may be carried out at any stage during nucleation, physical ripening, or growth, which is the initial stage of grain formation, and the most preferred method is reduction sensitization during the growth of silver halide grains. . Growing is a method in which reduction sensitization is performed while silver halide grains are growing by physical ripening or addition of a water-soluble silver salt and a water-soluble alkali halide. This means that it also includes a method in which reduction sensitization is carried out in a state in which the growth is carried out and then further growth is carried out.

The above-mentioned reduction sensitization is a method of adding a known reducing side to a silver halide emulsion, and a low PA of pAg 1 to 7 called silver ripening.
A method of growing or aging in an atmosphere of g, high p
It is possible to select either a method of growing or aging in a high pH atmosphere of pH 8 to 11, which is called H ripening. Moreover, two or more methods can also be used together.

The method of adding a reduction sensitizer is a preferred method because the level of reduction sensitization can be finely adjusted.

As reduction sensitizers, stannous salts, amines and polyamines, hydrazine derivatives, formamidine sulfinic acid, silane compounds, borane compounds, etc. are known. In the present invention, any of these known compounds can be used. Moreover, two or more kinds of compounds can be used in combination. Preferred compounds as reduction sensitizers include stannous chloride, thiourea dioxide, dimethylamine borane, ascorbic acid, and ascorbic acid derivatives. The amount of the reduction sensitizer to be added depends on the emulsion manufacturing conditions, so it is necessary to select the additive, but it is suitably in the range of 10-' to 104 mol per mol of silver halide.

Reduction sensitizers include water, alcohols, glycols,
It can be dissolved in a solvent such as ketones, esters, amides, etc. and added during particle formation.

Although it is possible to add the reduction sensitizer to the reaction vessel in advance, it is preferable to add it at an appropriate time during grain formation. Particles may be formed using an aqueous solution of It is also a preferable method to add the solution of the reduction sensitizer in several parts or continuously as the particles are formed.

More preferably, in the silver halide emulsion of the present invention, 5×10 −' moles or more of a palladium compound is added per mole of silver halide after the grain formation process and preferably before the desalting process.

The compound represented by the general formula (A) is contained in a silver halide emulsion layer, a hydrophilic colloid layer (intermediate layer, surface protective layer, yellow filter layer, antihalation layer, etc.), Or it is preferably contained in a layer adjacent thereto.

In addition, the amount added is I X l O-' ~ I X
l O-'mol/m, preferably 5 x 10
-' to I X 10-' mol/m, more preferably IXI O-@ to 3XI O-' mol/m.

The amount of the antifoggant or stabilizer used in the present invention cannot be determined uniquely depending on the method of addition or the amount of silver halide, but is preferably 10-7 mol-10 per mol of silver halide. -'' mol, more preferably 10-S to 10-2 mol.

The emulsion of the present invention can be used by mixing with other emulsions.The emulsion of the present invention can also be used by mixing two or more types of emulsions, or by mixing with one or two or more types of other emulsions. It can also be used.

It is also possible to mix particles of different sizes,
It is possible to mix halogens having different compositions, and also to mix halogens having different particle shapes. It is possible to mix monodisperse emulsions, it is also possible to mix polydisperse emulsions, and it is also possible to mix monodisperse and polydisperse emulsions. Preferably, the silver halide emulsion of the present invention is contained in an amount of at least 50% based on the total projected area.

The silver halide grains of the present invention are preferably composed mainly of (1111 planes).The plane index of the silver halide grains can be directly observed, for example, from an electron micrograph of a silver halide emulsion grain. Yes, and more precisely, Journal of the Chemical Society of Japan, 1984.(6), P, 942.
A quantitative method using dye adsorption as described in 947 is also possible. Mainly (111) plane means that (111) plane occupies 50% or more of the total area of the silver halide grain. Preferably it is 60% or more, more preferably 70% or more.

Grains mainly composed of (111) planes include tabular grains, octahedral normal crystal grains, those with missing corners, those with rounded corners, and even irregularly shaped grains.

In the present invention, tabular grains are most preferably used. A detailed explanation will be given below.

Next, the tabular silver decagenide emulsion preferably used in the present invention will be explained in detail.

In the tabular silver halide emulsion used in the present invention, the average aspect ratio means the average value of the diameter to thickness ratio of silver halide grains.

That is, it is the average value obtained by dividing the diameter of individual silver halide grains by the thickness. Here, the diameter refers to the diameter of a circle having an area equal to the projected area of the grains when the silver halide emulsion is observed using a microscope or an electron microscope. Therefore, the average aspect ratio of 2 to 1 or more means that the diameter of this circle is at least twice the thickness of the particle.

In the tabular silver halide grains used in the silver halide emulsion of the present invention, the grain size is at least twice the grain thickness, preferably 3 to 20 times, more preferably 4 to 15 times, particularly preferably It is 5 to 10 times. Further, the proportion of tabular silver halide grains in the projected area of all silver halide grains is 50% or more, preferably 70% or more, particularly preferably 85% or more.

By using an emulsion such as No. 2, a silver halide photographic material with excellent sharpness can be obtained. The reason why the sharpness is excellent is that light scattering by an emulsion layer using such an emulsion is extremely small compared to a conventional emulsion layer.

This can be easily confirmed by laboratory methods routinely used by those skilled in the art. The reason why the light scattering of an emulsion layer using a tabular silver halide emulsion is small is not clear, but it is thought to be because the main plane of the tabular silver halide emulsion is oriented parallel to the support surface.

Further, the diameter of the tabular silver halide grains is 012 to 2.
0 μm, preferably 0.3 to 10.0 μm, particularly preferably 0.4 to 5.0 μm. The thickness of the particles is preferably 0.5 μm or less. Here, the tabular silver halide grain diameter refers to the diameter of a circle having an area equal to the projected area of the grain. Further, the grain thickness is expressed as the distance between two parallel planes constituting a tabular silver halide grain.

In the present invention, more preferred tabular silver halide grains have a grain diameter of 0.3 μm or more and 1060 μm or less, a grain thickness of 0.3 μm or less, and an average (diameter/thickness) of 5 or more and 10 or less. be.

If it exceeds this range, it is undesirable because the photosensitive material may be bent, tightly rolled up, or may exhibit abnormal photographic performance when it comes into contact with a sharp object. More preferably, the particle diameter is 0.4 μm or more and 5.0 μm or less, and the average (diameter/
This is the case of a silver halide photographic emulsion in which grains having a thickness of 5 or more occupy 85% or more of the total projected area of all silver halide grains.

The tabular silver halide grains used in the present invention include silver chloride,
Any of silver bromide, silver chlorobromide, silver iodobromide, and silver chloroiodobromide may be used, but silver bromide, silver iodobromide containing 15 mol% or less of silver iodide, or silver chloride containing 50 mol% or less Silver chloroiodobromide and silver chlorobromide containing 2 mol % or less of silver iodide are more preferred, and the composition distribution in the mixed silver halide may be uniform or localized.

Further, the particle size distribution may be narrow or wide.

It can be easily prepared by referring to the methods described in No. 28 and No. 58-127921.

For example, seed crystals containing tabular grains or more than 40% by weight are formed in an atmosphere with a relatively high pAg value with a pBr of 1.3 or less, and silver and halogen solutions are simultaneously added while maintaining the pBr value at the same level. It is obtained by growing seed crystals. During this grain growth process, it is desirable to add a silver and halogen solution to prevent the generation of parent crystal nuclei.

The size of the tabular silver halide grains can be adjusted by controlling the temperature, selection of the type and quality of the solvent, the silver salt used during grain growth, the addition rate of the halide, etc.

When producing the tabular silver halide grains of the present invention, by using a silver halide solvent as necessary, grain size, grain shape (diameter/thickness ratio, etc.), grain size distribution,
It is possible to control the growth rate of particles. The amount of the solvent used is preferably in the range of 10-3 to 1.0% by weight of the reaction solution, particularly preferably in the range of 10-'-10-'% by weight. In the present invention, as the amount of solvent used increases, the particle size distribution becomes monodisperse and the growth rate can be accelerated, but the thickness of the particles also tends to increase as the amount of solvent used increases.

In the process of forming or physically ripening silver halide grains, cadmium salts, zinc salts, lead salts, thallium salts, iridium salts or their complex salts, rhodium salts or their complex salts, iron salts or iron complex salts, etc. may coexist. .

When producing the tabular silver halide grains used in the present invention, a silver salt solution (for example, A

A method of increasing the addition rate, amount, and concentration of the Br aqueous solution is preferably used.

In the present invention, the general formula (CN) and the general formula (Cn)
A yellow colored cyan coupler represented by the formula (CI) is more preferably used, and one represented by the general formula (CI) is particularly preferably used.

The yellow-colored cyan coupler of the present invention may be added to any layer in the light-sensitive material, but is preferably added to the light-sensitive emulsion layer, and has the same color sensitivity as the selenium-sensitized milk sublayer of the present invention. It is more preferably added to the red-sensitive silver halide emulsion layer of the present invention, and particularly preferably added to the selenium-sensitized red-sensitive silver halide emulsion layer and/or its adjacent light-sensitive emulsion layer.

The total amount added to the photosensitive material is o, oos ~ 0°30g/
It is preferably 0.02 to 0.20 g/n (, more preferably 0.03 to 0.15 g/r+).

The yellow-colored cyan coupler of the present invention can be added in the same manner as ordinary couplers, as described below.

The silver halide emulsion that can be used in combination with the present invention may include any of silver bromide, silver iodobromide, silver iodochlorobromide, and silver chlorobromide. Preferred silver halide is silver iodobromide or silver iodochlorobromide containing 30 mol % or less of silver iodide.

The tabular grains of the present invention are used in Cripe's "Theory and Practice of Photography" J.

It can be easily prepared by the method described in No. 57, etc.

In the silver halide emulsion used in the present invention, the crystal structure of the silver halide grains may be --like, the inside and outside may have different halogen compositions, or they may have a layered structure. These emulsion grains are described in British Patent No. 1.
No. 027,146, U.S. Patent No. 3,505.068;
No. 4,444°877 and patent application No. 58-24846
It is disclosed in No. 9 etc. Furthermore, silver halides having different compositions may be bonded by epitaxial bonding, or compounds other than silver halide such as silver rhodan or lead oxide may be bonded.

The silver halide emulsion of the present invention preferably has a distribution or structure in terms of halogen composition in its grains.
Typical examples are JP Publication No. 43-13162 and JP Patent Publication No. 6
These are core-shell type or double structure type particles having a halogen composition in the interior and surface layer of the particle as disclosed in Japanese Patent Application Laid-open No. 1-215540, JP-A No. 60-222845, and JP-A No. 61-75337. In such particles, the shape of the core portion and the overall shape including the shell may be the same or different. In addition, instead of a simple double structure, it is possible to create a triple structure as disclosed in JP-A No. 60-222844, or a multilayer structure with more than that, or a halogen with a different composition on the surface of the core-shell double structure particle. You can apply a thin layer of silver.

In order to provide a structure inside the particle, it is possible to create a particle having not only the enveloping structure as described above but also a so-called bonding structure. These examples are published in Japanese Patent Application Laid-Open No. 59-133.

54, etc. #A matching crystal can be produced by bonding it to an edge or part of a corner of a host crystal, or to a screen, with 11w1 different from that of the host crystal. Such a bonded crystal can be formed even if the host crystal is uniform in terms of halogen composition or has a core-shell structure.

In the case of a bonded structure, a combination of silver halides is of course possible, but a bonded structure can be obtained by combining silver halide with a silver salt compound that does not have a rock salt structure, such as silver rhodan or silver carbonate. Further, non-silver salt compounds such as PbO may also be used if a bonded structure is possible.

In the case of silver iodobromide grains having these structures, for example, in core-shell type grains, the core part may have a high silver iodide content and the shell part may have a low silver iodide content, or conversely, the core part may have a low silver iodide content. Grains with a low silver iodide content and a high shell part may be used. Similarly, grains with a bonded structure may have a high silver iodide content in the host crystal and a relatively high silver iodide content in the bonded crystal. The same is true for the silver chloride content, which may be low grains or vice versa.

In addition, the boundaries between particles with these structures with different halogen compositions may be clear boundaries, or may be unclear boundaries due to the formation of mixed crystals due to the difference in crystallization, or may be actively continuous. It is also possible to add some structural changes.

The surface may be modified as disclosed in JP-A-60-221320, No. 2306447C2.

The silver halide emulsion used in the present invention is preferably a surface latent image type emulsion, but an internal latent image type emulsion can also be used by selecting the developer or development conditions, as disclosed in JP-A-59-133542. can. A shallow internal latent image type emulsion covered with a thin shell can also be used depending on the purpose.

Halogenation 1 to promote ripening! Solvent is useful0
For example, it is known to have an excess of halogen ions present in the reactor to promote ripening. It is therefore clear that ripening can be accelerated simply by introducing a halide salt solution into the reactor. Other ripening agents can also be used. These ripening agents can be blended in their entirety into the dispersion medium in the reactor before adding silver and halide salts, or one or more halide salts, silver salts, or peptizers can be added to the dispersion medium in the reactor. It can also be introduced into the reactor at the same time as adding. As a further variant, the ripening agent can also be introduced independently at the halide salt and silver salt addition stages.

As P components other than halogen ions, ammonia or amine compounds, thiocyanate salts such as alkali metal thiocyanate salts, especially sodium and potassium thiocyanate salts, and ammonium thiocyanate salts can be used.

In the emulsion of the present invention, it is preferable that the silver iodide content among the grains is more uniform.0 Judgment as to whether the silver iodide content among the grains is uniform is carried out by the EPMA method (E
Iectron-Probe Micr.

Analyzer method) can be used.

In this method, a well-dispersed sample is prepared so that the emulsion grains do not come into contact with each other, and then an electron beam is irradiated. Elemental analysis of extremely small parts can be performed by X-ray analysis using electron beam excitation.

By this method, the halogen composition of each grain can be determined by determining the characteristic xvA intensity of silver and iodine emitted from each grain.

When the distribution of silver iodide content between grains is measured by the EPMA method, the relative standard deviation is 50% or less, further 35% or less,
In particular, it is preferably 20% or less.

In the silver halide bill splitter of the present invention, cadmium salt, zinc salt,
A thallium salt, an iridium salt or a complex salt thereof, a rhodium salt or a complex salt thereof, an iron salt or an iron complex salt, etc. may be coexisting. Most preferred are iridium salts.

(Examples) The present invention will be explained in detail below using Examples, but the present invention is not limited thereto.

After adding 35 cc of an aqueous solution containing 5.0 g of potassium bromide and 35 cc of an aqueous solution containing 3.2 g of potassium bromide and 0.98 g of potassium iodide at a flow rate of 70 cc/min for 30 seconds, the PAg was increased to 10 and aged for 30 minutes. Breeding milk necropsy was then prepared.

Next, a predetermined amount of an aqueous solution containing 145 g of silver nitrate and an aqueous solution of a mixture of potassium bromide and potassium iodide were added in equimolar amounts at a predetermined temperature, a predetermined pAtg, and at a rate close to the critical growth rate. A core emulsion was prepared. Subsequently, equimolar amounts of the remaining silver nitrate aqueous solution and an aqueous solution of a mixture of potassium bromide and potassium iodide having a composition different from that used in preparing the core emulsion were added at a rate close to the critical growth rate to coat the core. Core/shell type silver iodobromide tabular emulsions 1 to 5 were prepared.

The tiI node of the asvector ratio is determined by p during core and shell preparation.
It was obtained by selecting Ag. The results are shown in Table 1-1.

]) For 1,000 emulsion grains, measure the aspect ratio of each individual grain, select grains with a larger aspect ratio than grains that account for 50% of the total projected area, and calculate the average value of the aspect ratio of these grains.

The light-sensitive material of the present invention only needs to have at least one silver halide emulsion layer of a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer on the support. There are no particular limitations on the number and order of the silver emulsion layer and the non-photosensitive layer. A typical example is a silver halide photographic light-sensitive material having on a support at least one photosensitive layer consisting of a plurality of silver halide emulsion layers having substantially the same color sensitivity but different photosensitivity. The photosensitive layer is a unit photosensitive layer that is sensitive to blue light, green light, or red light, and in a multilayer silver halide color photographic light-sensitive material, generally the unit photosensitive layer is A red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer are arranged in this order from the support side. However, depending on the purpose, the above-mentioned installation order may be reversed, or the installation order may be such that different photosensitive layers are sandwiched between the same color-sensitive layer.

Non-photosensitive layers such as various intermediate layers may be provided between the above-mentioned silver halide photosensitive layers and between the uppermost layer and the lowermost layer.

The intermediate layer includes JP-A Nos. 61-43748 and 59-1.
No. 13438, No. 59-113440, No. 61-20
Coupler, DIR compound, etc. as described in No. 037 and No. 61-20038 may be included,
It may also contain a commonly used color mixing inhibitor.

The plurality of silver 10-genide emulsion layers constituting each unit photosensitive layer are high-sensitivity emulsion layers, as described in German Patent No. 1.121.470 or British Patent No. 923.045.
A two-layer structure of low-speed emulsion layers can be preferably used. Usually, it is preferable to arrange the layers so that the photosensitivity decreases toward the support, and a non-photosensitive layer may be provided between each halogen emulsion layer. In addition, JP-A-57
-112751, 62-200350, 62-
As described in Nos. 206541 and 62-206543, a low-sensitivity emulsion layer may be provided on the side far from the support, and a high-sensitivity emulsion layer may be provided on the side close to the support.

As a specific example, from the side farthest from the support: low sensitivity blue sensitive layer (BL) / high sensitivity blue sensitive layer (BH) / high sensitivity green sensitive layer (GH) / low sensitivity green sensitive layer (GL) /High-sensitivity red-sensitive layer (RH) /Low-sensitivity red-sensitive layer (RL)
or BH/BL/GL/GH/RH/RL, or BH/BL/GH/GL/RL/R)I, or the like.

Further, as described in Japanese Patent Publication No. 55-34932, from the side farthest from the support, the blue-sensitive layer/GH/R
They can also be arranged in the order of H/GL/RL. Furthermore, as described in JP-A-56-25738 and JP-A-62-63936, the blue-sensitive layer/GL/RL/GH/R)I may be arranged in this order from the farthest side from the support. You can also do it.

In addition, as described in Japanese Patent Publication No. 49-15495, the upper layer is a silver halide emulsion layer with the highest sensitivity, the middle layer is a silver halide emulsion layer with lower sensitivity, and the lower layer is more sensitive than the middle layer. An example is an arrangement consisting of three layers with different photosensitivity, in which a silver halide emulsion layer with a low density is disposed and the photosensitivity gradually decreases toward the support. Even when it is composed of three layers with different photosensitivity, as described in JP-A No. 59-202464,
In the same color-sensitive layer, medium-sensitivity emulsion layer/high-sensitivity emulsion layer/low-sensitivity emulsion layer may be arranged in this order from the side remote from the support.

In addition, high-sensitivity emulsion layer / low-sensitivity emulsion layer / medium-sensitivity emulsion layer,
Alternatively, they may be arranged in the order of low-speed emulsion layer/medium-speed emulsion layer/high-speed emulsion layer, etc.

Furthermore, even in the case of four or more layers, the arrangement may be changed as described above.

As mentioned above, various layer structures and arrangements can be selected depending on the purpose of each photosensitive material.

In the present invention, it is preferred to use non-photosensitive fine grain silver halide. Non-photosensitive fine grain silver halide is a silver halide fine grain that is not exposed to light during imagewise exposure to obtain a dye image and is not substantially developed during the development process, and is preferably not fogged in advance. .

02 to 0.2 μm is more preferable.

Fine-grain silver halide can be prepared in the same manner as ordinary photosensitive silver halide. In this case, the surface of the silver halide grains does not need to be optically sensitized, nor is spectral sensitization necessary. However, it is preferable to add a known stabilizer such as a triazole-based, azaindene-based, benzothiazolium-based, or mercapto-based compound, or a zinc compound before adding this to the tsutsufu liquid. This layer containing fine silver halide grains can preferably contain colloidal silver.

The saturated film thickness is defined as 90% of the maximum swollen film thickness reached at that time, and is defined as the time until the saturated film thickness reaches 172.

Membrane swelling rate T17. can be adjusted by adding a hardening agent to gelatin as a binder or by changing the aging conditions after forming the tube. Further, the swelling rate is preferably 150 to 400%. The swelling ratio can be calculated from the maximum swollen film thickness under the conditions described above according to the formula: (maximum swollen film thickness - film thickness)/film thickness.

The color developing solution used in the development of the light-sensitive material of the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine color developing agent as a main component. Aminophenol compounds are also useful as color developing agents, but p-fuynylenediamine compounds are preferably used, representative examples of which include 3-methyl-4-amino-N,N-diethylaniline, -Methyl-4-amino-N-ethyl-N-
β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-β-
Examples include methoxyethylaniline and their sulfates, hydrochlorides, p-toluenesulfonates, and the like. Among these, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline sulfate is particularly preferred. 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, chloride salts, bromide salts,
It is common to include development inhibitors or antifoggants such as iodide salts, benzimidazoles, benzothiazoles or mercapto compounds. If necessary, various preservatives such as hydroxylamine, diethylhydroxylamine, sulfites, hydrazines such as N,N-biscarboxymethylhydrazine, phenyl semicarbazides, triethanolamine, and catechol sulfonic acids, 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, auxiliary developing agents such as l-phenyl-3-pyrazolidone, viscosity.

This can be cited as a representative example.

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-virapritone, or aminophenols such as N-methyl-p-aminophenol. Alternatively, they can be used in combination.

The p)l of these color developing solutions and black and white developing solutions is 9 to 12.
It is common to be. 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 light-sensitive material, and by reducing the bromide ion concentration in the replenisher,
It can also be set to 0- or less. When reducing the amount of replenishment, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the area of contact with the air in the processing tank.

The contact area between the photographic processing solution and air in the processing tank can be expressed by the aperture ratio defined below.

That is, the above aperture ratio is preferably 0.1 or less, more preferably 0.001-0.05. As a method for reducing the aperture ratio in this way, it is better to provide a shield such as a floating lid on the surface of the photographic processing liquid in the processing tank, as described in Japanese Patent Application Laid-Open No. 1-82.
Method using a movable lid described in No. 033, JP-A-63
The slit development processing method described in Japanese Patent No. 216050 can be mentioned. Reducing the aperture ratio is important not only for both color development and black and white development processes, but also for subsequent processes,
For example, it is preferable to apply it to all steps such as bleaching, bleach-fixing, fixing, washing with water, and stabilization. Furthermore, the amount of replenishment can be reduced by using means for suppressing the accumulation of bromide ions in the developer.

The time for color development processing is usually set between 2 and 5 minutes, but the processing time can be further shortened by using high temperature, high pH, and high concentration of color developing agent.

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. As the bleaching agent, for example, compounds of polyvalent metals such as iron CI [), peracids, quinones, nitro compounds, etc. are used. Typical bleaching agents include organic complex salts of iron (II),
For example, aminopolycarboxylic acids such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, glycol etherdiaminetetraacetic acid, or complex salts of citric acid, tartaric acid, malic acid, etc. can be used. Among these, aminopolycarboxylic acid iron (I[) complex salts, including ethylenediaminetetraacetic acid iron (I[[) complex salt and 1,3-diaminopropanetetraacetic acid iron (I[) complex salt], require rapid processing and environmental pollution. Preferable from the viewpoint of prevention. In addition, iron aminopolycarboxylate (III

Preference is given to the compounds described in No. 95.630. Further preferred are the compounds described in US Pat. No. 4,552,834. These bleach accelerators may be added to the photosensitive material. These bleach accelerators are particularly effective when bleach-fixing color light-sensitive materials for photography.

In addition to the above-mentioned compounds, the bleaching solution and bleach-fixing solution preferably contain an organic acid for the purpose of preventing bleach staining. Particularly preferred organic acids have an acid dissociation constant (pKa) of 2.
~5, specifically acetic acid, propionic acid,
Hydroxyacetic acid and the like are preferred.

Examples of fixing agents used in fixing solutions and bleach-fixing solutions include thiosulfates, thiocyanates, thioether compounds, thioureas, and large amounts of iodide salts, but thiosulfates are commonly used. Of these, ammonium thiosulfate is the most widely used. Further, a combination of thiosulfate, thiocyanate, thioether compound, thiourea, etc. is also preferred. As the preservative for the fixer and bleach-fixer, sulfites, bisulfites, carbonyl bisulfite adducts, or sulfinic acid compounds described in European Patent No. 294,769A are preferred. Further, it is preferable to add various aminopolycarboxylic acids and residual phosphonic acids to the fixing solution and bleach-fixing solution for the purpose of stabilizing the solution.

In the present invention, the fixer or bleach-fixer contains pHI
For II adjustment, compounds with pKa of 6.0 to 9.0, preferably imidazole, 1-methylimidazole, 1-
It is preferable to add 0.1 to 10 mol/1 of imidazoles such as ethylimidazole and 2-methylimidazole.

The total time of the desilvering step is preferably as short as possible without causing desilvering defects. The preferred time is 1 minute to 3 minutes, more preferably 1 minute to 2 minutes. In addition, the processing temperature is 25°C to 5°C.
0°C1 is preferably 35°C to 45°C. In a preferred temperature range, the desilvering rate is improved and the occurrence of staining after processing is effectively prevented.

In the desilvering step, it is preferable that stirring be as strong as possible. Specific methods for strengthening the agitation include the method of impinging a jet of processing liquid on the emulsion surface of the photosensitive material described in JP-A-62-183460, and the method described in JP-A-62-183.
No. 461, a method of increasing the stirring effect using a rotating means, and further improving the stirring effect by moving the photosensitive material while bringing the emulsion surface into contact with a wiper blade provided in the liquid to create turbulence on the emulsion surface. Examples include a method of increasing the circulation flow rate of the entire treatment liquid. Such means for improving agitation is effective for all bleaching solutions, bleach-fixing solutions, and fixing solutions. It is believed that improved stirring speeds up the supply of bleach and fixing agent into the emulsion film, and as a result increases the desilvering rate. Further, the agitation improving means described above is more effective when a bleach accelerator is used, and can significantly increase the accelerating effect and eliminate the fixing inhibiting effect caused by the bleach accelerator.

It is preferable that the photosensitive material conveying means described in Japanese Patent Application No. 191259 be developed. As described in the above-mentioned Japanese Patent Laid-Open No. 60-191257, such a conveying means can significantly reduce the carry-over of the processing liquid from the pre-bath to the post-bath, and is highly effective in preventing deterioration of the performance of the processing liquid. Such effects are particularly effective in shortening the processing time in each step and reducing the amount of processing liquid replenishment.

The silver halide color photographic light-sensitive material of the present invention is generally subjected to a water washing and/or stabilization process 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. Can be set over a wide range. 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 color photosensitive materials of the present invention, as a solution to these problems,
The method for reducing calcium ions and magnesium ions described in JP-A No. 62-288.838 can be used very effectively. Also, JP-A-57-8.542
