Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material and a processing method thereof. The present invention relates to a method for providing improved silver halide color photographic materials.

(Prior Art) In recent years, demands for silver halide color photographic materials (hereinafter referred to as "photosensitive materials") have become extremely strict, and in particular, as cameras have become smaller, there has been a demand for smaller screen sizes of photosensitive materials. Therefore, there is an extremely strong demand for technological development for improving image quality (particularly graininess) in photosensitive materials.

As a technique for improving this graininess, for example, JP-A-Sho! 2-/
jJu2r, JP-A-60-/31331r, JP-A-40-/Hiroshi 3331, and Journal of Imaging Science Kota Volume! As described on page 3 of the issue, double W! has a core portion with a high silver iodide content and a shell portion with a low silver iodide content inside the emulsion grain. A method of increasing the efficiency of use of incident light is to separate the functions of the emulsion grains from light reception to image formation into the core and shell parts as much as possible using manufactured core/shell type emulsion grains. It is powerful.

On the other hand, in recent years, with the spread of so-called minilabs, there has been a growing demand for simpler, faster and lower cost processing of photosensitive materials, and it has become essential to simplify processing steps, shorten processing time, and reduce the amount of processing chemicals used. It's here.

Generally, the basic steps in processing color photosensitive materials are a color development step and a desilvering step. In the color development process, the silver halide exposed to light is reduced to a color developer to produce silver, and the oxidized color developer reacts with a coupler to give a dye image.Next In the desilvering process, the silver produced in the color development process is oxidized by the action of an oxidizing agent (commonly known as a bleaching agent), and is then cleaved by a silver ion complexing agent, commonly known as a fixing agent. Through this desilvering process, only a dye image 1'4! is created on the color photosensitive material.The above desilvering process consists of a white bath containing bleach and a fixing bath containing a fixing agent. In some cases, the process is carried out in two baths, and in other cases, it is carried out in a bleach-fixing bath in which a bleaching agent and a fixing agent coexist.

Red blood salts, dichromates, ferric chloride, aminopolycarboxylic acid metal salts, and persulfates have been used for general VC bleaching. Carboxylic acid metal salts have come to be used.

However, metal abanopolycarboxylic acid metal salt has a weak oxidizing power, and therefore cannot necessarily be said to be an excellent bleaching agent in terms of whitening speed.

In particular, when a silver halide emulsion having a phase with a high silver iodide content, such as the double-structure grains mentioned above, is used in a light-sensitive material, the bleaching rate tends to be slow, and desilvering failure is a serious problem. It reached the top.

Conventionally, as a method for solving the problem of poor desilvering in the processing of photosensitive materials, US Pat. ♂73゜rsr issue, JP-A-53-9Jt1.30, same! ! −, 26j06, same≠

0, Tokko Akira≠! - There is a known method of adding a bleach accelerator to a bleach bath, a bleach-fixing bath, or a pre-bath thereof, as described in 2 and 2, but it is not always satisfactory to promote bleaching. However, there were problems such as reducing the amount of processed material and producing poorly soluble precipitates.

Further, a method for accelerating bleaching by adding a compound similar to the general formula CI)VC@ of the present invention to a sensitive material or a processing solution is disclosed in US Patent No. It is disclosed in No. 21.3.

In addition, as a method of promoting bleaching and/or bleach-fixing, processing at a low pH where the oxidizing power of aminopolycarboxylic acid metal salts is strongly exerted is carried out, but cyan-dye concentration decreases and is blocked. There was a problem that the thiosulfate and ethyl sulfite salts present in the solution were decomposed quickly (and the performance of the processing solution was unstable).

Under these circumstances, the desilvering technology for photosensitive materials using silver halide emulsions having a phase with a high silver iodide content has not been fully established, and There was no disclosure regarding improvement of the desilvering process of a light-sensitive material containing a silver halide emulsion having a phase of .

(Objectives of the Invention) The first object of the present invention is to provide a photosensitive material that has excellent graininess and has a high desilvering rate in various bleach baths or bleach-fixing baths. The object of the present invention is to provide a method for rapidly processing excellent photosensitive materials.

(Structure of the Invention) The object of the present invention is to provide a core consisting essentially of silver iodobromide, which has at least one photosensitive silver halide emulsion layer on a support and contains 10 or more moles of silver iodide; Cover the core! In a silver halide color photographic processing method containing silver halide emulsion grains having a layered structure consisting of shells consisting essentially of silver iodobromide or silver bromide containing silver iodide of less than 100%, the following general formula is used.

A preferred embodiment of the light-sensitive material of the present invention has at least one red-sensitive emulsion layer, one green-sensitive emulsion layer, and one blue- and one-color emulsion layer on a support, and at least one of these emulsion layers has at least one emulsion layer. It contains a silver halide emulsion consisting of core-shell type silver halide grains.

In a preferred embodiment of the above-mentioned silver halide emulsion, the core of the silver halide grains consists essentially of silver iodobromide containing silver iodide in a molar proportion of 10 or more, more preferably 20 molar or more; The shell covering the core has a silver iodide content of j
It consists essentially of silver bromide or silver bromide of less than molar proportion.

The core may contain silver iodide uniformly, or may have a variety of structures consisting of phases with different silver iodide contents. In the latter case, the average value of the silver iodide content of the core is i
It is at least 0 molar, more preferably at least 20 molar. Furthermore, the expression "consisting essentially of silver iodobromide" means that the composition mainly consists of silver iodobromide, but may also contain other components up to about 1 mole.

In a more preferred embodiment of the core-shell emulsion of the present invention, the diffraction angle (2θ) is in the range of 3t to μ2°, and β
When the curve of diffraction intensity versus diffraction angle of the (λλO) plane of silver halide is obtained using a line, there are two diffraction maxima: a diffraction peak corresponding to the core part and a beak corresponding to the shell part.
These particles have a structure in which there is one minimum point between them.

Although the size distribution of the emulsion of the present invention does not matter, it is more preferable that the emulsion is monodisperse.

The term "monodisperse" used here means that the weight or number of particles is small (or j% of the average particle size is within the range of ≠ 0ely). Although there is no restriction, twinned supernormal crystals are more preferable.

Still another preferred embodiment is that the relative standard deviation of the silver iodide content of individual grains of the nuclear silver iodobromide emulsion is 20% or less, preferably 12% or less. That's true. The silver iodide content of individual emulsion grains is, for example,
It can be determined by analyzing the composition of individual particles using a line microanalyzer. The "relative standard deviation of the silver iodide content of individual grains" here refers to the silver iodide content when the silver iodide content of at least 100 emulsion grains is measured using an X-ray microanalyzer, for example. This value is obtained by dividing the standard deviation of the silver iodide content by the average silver iodide content and multiplying it by ioo.

To add these compounds to a photosensitive material, they can be added to the coating solution as they are, or they can be dissolved at an appropriate concentration in a solvent that does not have an adverse effect on the silver halide color photographic material, such as water or alcohol. It can be added as These compounds can also be added by dissolving them in a high boiling point organic solvent and/or a low boiling point organic solvent and emulsifying and dispersing them in an aqueous solution.

Furthermore, when adding these compounds to the processing solution, it is common to dissolve them in water, alkali, organic solvents, etc. beforehand, but they may also be added directly to the processing solution in the form of powder.

The silver iodobromide emulsion of the present invention can be formed by first forming a silver iodobromide grain serving as a core, and then coating the core with silver iodobromide or silver bromide.

In order to make the silver iodide content of individual grains of the emulsion uniform, first, the size and crystal habit of the core silver iodobromide grains and the intergrain silver iodide content distribution of the core grains should be adjusted as much as possible. It is important to make it uniform.

For this purpose, an aqueous solution of silver nitrate and an aqueous solution of a mixture of alkali metal iodides and bromides are added by the double jet method in the presence of a protective colloid.

In particular, from the viewpoint of narrowing the silver iodide content distribution between grains, the pAg during addition was adjusted from 7.0 to 10.0. L') Preferably? It is important to keep it constant in the range from , 0 to 0. Further, it is preferable that the degree of supersaturation of the solution during addition is high; for example, as described in US Pat. An effective method is as described in No. Lj, in which addition is carried out while increasing the concentration of the additive solution until the crystal growth rate reaches 30 to 100 degrees of the critical crystal growth rate. Further, during addition, it is preferable to have an appropriate amount of a silver halide solvent such as ammonia, thiocyanate, and thioether compound present.

In order to form the silver iodobromide emulsion grains of the present invention, it is necessary to coat the core formed by the above method with silver bromide or silver iodobromide as uniformly as possible.

To do this, add a silver nitrate aqueous solution and an alkali halide aqueous solution to the emulsion containing the core particles, and add p A g to Q.
While keeping the crystal growth rate constant within the range of from It is desirable to carry out the addition at a relatively high degree of supersaturation. By this method, an emulsion with a narrow distribution of silver iodide content among the particles was obtained.
