Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a silver halide color photographic light-sensitive material (hereinafter abbreviated as a light-sensitive material) having a magnetic recording layer containing magnetic particles, and particularly to a photographic property which is stable even during running processing. And to provide a processing method with excellent magnetic information reading performance.

2. Description of the Related Art Conventionally, in a silver halide photographic light-sensitive material (hereinafter abbreviated as a light-sensitive material), it is almost impossible to input or output various kinds of information at the time of photographing or printing, and it is slightly optical. It was only possible to input / output the shooting date and time. By the way, JP-A-4-68336 and JP-A-4-68336.
No. 73737, or as disclosed in Japanese Patent Laid-Open No. 5-88283, by providing a transparent magnetic recording layer on the entire surface of a light-sensitive material, shooting conditions such as date and time of shooting, weather, reduction / enlargement ratio, Number of reprints, areas you want to zoom,
It is possible to input the message, development, print conditions, etc. to the sensitive material. Also, various information can be provided even when inputting to video equipment such as TV / video.
This is a promising method for the future.

On the other hand, in such a method for processing a light-sensitive material, color development, desilvering, washing with water and stabilizing treatment are generally carried out. By the way, with the recent widespread use of in-store processing such as in a minilab, there is an increasing demand for a shorter delivery time and a smaller amount of waste liquid. Therefore, various studies have been made to shorten the processing steps and reduce replenishment. In particular, in order to shorten the color development time, high concentration of the main agent and increase in processing temperature do not impair photographic characteristics,
This is one of the most desirable methods because it can shorten the processing time. By the way, when the silver halide color photographic light-sensitive material having the magnetic recording layer according to the present invention is subjected to a running process under the condition that the replenishment amount to the developing solution is small, the magnetic recording performance is deteriorated (S It has been found that satisfactory information cannot be provided, and that the change in the sensitivity of yellow and the change in the density of cyan are particularly remarkable before and after running, which affects the photographic properties.

[0004]

The object of the present invention is to provide a processing method for a silver halide color photographic light-sensitive material without deteriorating the / N ratio, and further to provide a processing method having excellent photographic performance.

[0005]

It has been found that the above problems can be solved by carrying out the following processing method. (1) A silver halide color photograph having at least one red-sensitive layer, green-sensitive layer and blue-sensitive layer on one side of a transparent support, and a magnetic recording layer containing magnetic grains on the other side. In the processing method in which a light-sensitive material is processed with a color developing solution, desilvered, washed with water and / or stabilized, the liquid level of the color developing solution and / or the liquid level of the color developing replenisher in the color developing replenisher tank is changed. A method of processing a silver halide color photographic light-sensitive material, which comprises processing in a state of being covered with a fluid layer of a floating fluid. (2) The processing method according to (1), wherein the floating fluid is liquid paraffin or liquid saturated hydrocarbon. (3) The photosensitive layer is characterized in that at least 50% of the total projected area of chemically sensitized silver halide grains is a photosensitive emulsion layer composed of tabular grains having an aspect ratio of 2: 1 or more.

Further, at least 50% of the total projected area of silver halide grains chemically sensitized in the photosensitive layer of the silver halide color photographic light-sensitive material is a light-sensitive emulsion layer composed of tabular grains having an aspect ratio of 2: 1 or more.

However, the order of installation may be reversed depending on the purpose, or the order of installation may be such that different photosensitive layers are sandwiched between the same color-sensitive layers. A non-photosensitive layer may be provided between the above-described silver halide photosensitive layers and as the uppermost layer and the lowermost layer. These may contain a coupler, a DIR compound, a color mixing inhibitor, etc. described later. A plurality of silver halide emulsion layers constituting each unit photosensitive layer is DE 1,121,470 or GB 923,045.
It is preferable to arrange the two layers of the high-sensitivity emulsion layer and the low-sensitivity emulsion layer so that the sensitivities are lowered toward the support as described above. In addition, JP-A-57-112751, 62-
As described in 200350, 62-206541 and 62-206543, a low-sensitivity emulsion layer may be provided on the side farther from the support and a high-sensitivity emulsion layer may be provided on the side closer to the support. As a specific example, from the side farthest from the support, low-sensitivity blue photosensitive layer (BL) / high-sensitivity blue photosensitive layer (BH) / high-sensitivity green photosensitive layer (GH) / low-sensitivity green photosensitive layer (GL) / High-sensitivity red photosensitive layer (RH) / Low-sensitivity red photosensitive layer (RL), or BH / BL / GL / GH / RH / RL, or BH / BL / GH / GL / RL / RH It can be installed in the order of.

The preferred silver halide used in the present invention is silver iodobromide, silver iodochloride, or silver iodochlorobromide, containing up to about 30 mol% silver iodide. Particularly preferred is silver iodobromide or silver iodochlorobromide containing from about 2 mol% to about 10 mol% silver iodide.

The tabular silver halide emulsion preferably used in the present invention will be described in detail below. In the tabular silver halide emulsion used in the present invention, the aspect ratio means the ratio of diameter to thickness of silver halide grains. That is, it is a value obtained by dividing the diameter of each silver halide grain by the thickness. Here, the diameter means the diameter of a circle having an area equal to the projected area of a grain when the silver halide emulsion is observed with a microscope or an electron microscope. Therefore, the aspect ratio of 2: 1 or more means that the diameter of this circle is twice or more 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 2 times the grain thickness.
It is at least 3 times, preferably 3 to 20 times, more preferably 4 to 15 times, particularly preferably 5 to 10 times.

By using such an emulsion, a silver halide photographic light-sensitive material having excellent sharpness can be obtained. The sharpness is excellent because the light scattering by the emulsion layer using such an emulsion is extremely small as compared with the conventional emulsion layer. This can be easily confirmed by those skilled in the art by experimental methods that can be routinely used. The reason why the light scattering of the emulsion layer using the tabular silver halide emulsion is small is not clear, but it is considered that the main surface of the tabular silver halide emulsion is oriented parallel to the support surface.

The tabular silver halide grains have a diameter of 0.
The thickness is 2 to 20 μm, preferably 0.3 to 10.0 μm, and 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 means the diameter of a circle having an area equal to the projected area of the grain. The grain thickness is represented by 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 10.0 μm or less.
