Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a halogenated color photographic light-sensitive material containing a color developing agent, an image forming method and a digital image information producing method.

[0002]

2. Description of the Related Art A silver halide color photographic light-sensitive material usually has a layer for recording blue light to form a yellow dye image, a layer for recording green light to form a magenta dye image, and a layer for recording red light. The developer is oxidized in the process of reducing silver halide grains containing a latent image formed on the surface of the silver halide by exposure to light during development processing, including a layer for forming a cyan dye image, and oxidizing the developer. A dye image is formed by coupling of the body with the coupler.

Heretofore, a compound that forms a dye by coupling with a coupler has been used as a developing solution from outside a photosensitive material.
Had been supplied. However, the burden on the developer maintenance, the complexity of waste liquid treatment, and the environment is large,
In recent years, from the viewpoint of rapidity, a method of performing color development by incorporating a developing agent into a photosensitive material has been proposed in recent years.
For example, U.S. Pat.
21, 240, JP-A-59-231538, and 60
No. -128438 and the like.

Usually, since a developing agent is a reducing agent, a compound which is easily oxidized by oxygen molecules in the air is generally used, and a developing agent incorporating such a compound in a photosensitive material is not suitable. . In this field, as developing agents which can be incorporated, JP-A-8-227131 and EP-072
7708A1, hydrazines described in JP-A-8-234390, U.S. Pat. No. 4,021,240,
P-aminophenols described in 0-128439 have been proposed.

[0005] A concern as a technique for incorporating a developing agent into a photosensitive material is performance degradation during storage of the photosensitive material, and different dyes are formed even when the same color is used with a different developing agent. Because yellow, magenta,
Cyan coupler dyes are required to have good color separation. In particular, cyan coupler dyes have been desired to have a longer wavelength because they have a sufficiently long wavelength, which is advantageous for color separation. In particular, in the case of the built-in hydrazine developing agent, since the dye after coupling is an azo dye, the long wavelength of the cyan coupler dye is not sufficient, which is a problem in color separation.

[0006] As a cyan dye-forming coupler (cyan coupler) in a conventional developing agent, phenols and naphthols are typical, and naphthols have been used. Compounds having a substituent at the 5-position of 1-naphthols are disclosed in JP-A-60-237448 and JP-A-7-237448.
As described in JP-A-333794, the color developing property and color separation are poor in the built-in developing agent system, and the storage stability is also a problem.

[0007]

In the silver halide photographic light-sensitive material according to the present invention, dyes having absorption in various wavelength ranges can be used for the purpose of preventing irradiation and halation.

These dispersions are preferably formed in a hydrophilic binder such as gelatin. A method for preparing colloidal silver particles is described in U.S. Pat. No. 2,688,601. If necessary, a desalting method for removing an excess salt known in a method for preparing a silver halide emulsion may be performed.

In a coating solution containing a hydrophilic binder, for example, it may be prepared by reacting silver nitrate and sodium sulfide, or gold chloride and a reducing agent. Silver, silver sulfide, palladium sulfide and the like are preferably used as physical development nuclei.

When fixing silver halide by such a method, it is necessary that a reducing agent capable of causing physical development is present in a layer containing physical development nuclei. If a non-diffusible reducing agent is used, it is necessary to add it to the layer. No problem. As the reducing agent having such a function, the above-mentioned auxiliary developer is preferably used.

The silver halide may be fixed without using a physical development nucleus or a reducing agent. In this case, it is desired that silver ions are subjected to salt substitution by a so-called silver halide solvent to produce a non-photosensitive silver salt.

In each case, a known silver halide solvent can be used. For such applications,

<Preparation of photosensitive materials 102 to 127> In the preparation of the photosensitive material 101, the cyan coupler C-
Light-sensitive materials 102 to 127 were prepared in the same manner except that No. 1 and the color developing agent A-64 were replaced as shown in Table 3. <Evaluation of sample> Photosensitive material 1 produced as described above
01 to 127 were processed as follows. Also, 40
Those stored for 7 days at 80 ° C. and 80% RH were treated similarly. That is, each photosensitive material is exposed to light at 1000 Lux for 1/100 second through an optical wedge and a red filter, and hot water of 40 ° C. is applied to the exposed surface of the photosensitive material for 15 m.
1 / m ^2, and the processing sheet P-1 and the respective film surfaces were overlapped with each other.
Heat development was performed for 2 seconds. When the photosensitive material was peeled off after the processing, a wedge-shaped image of cyan color was obtained. The transmission density of each sample was measured with red light to obtain a characteristic curve. The sensitivity was defined as the reciprocal of the exposure corresponding to a density 0.30 higher than the fog density. Each sensitivity was shown as a relative value when the red sensitivity of Sample 101 was set to 100. Table 3 shows the results.

[0309]

[Table 3]

[0310] Sample 101 (Comparative Coupler 1) had a lower maximum red density than the coupler of the present invention, and the fog after storage was deteriorated. In Sample 102 (Comparative Coupler 2), the formed dye was in the green region, and the red density was extremely low. Sample 103 had extremely high fog and poor storage stability.
The coupler and color developing agent of the present invention had a high maximum red density and good color developability. Also, the storage stability was excellent.

[0311] The spectral absorption of the exposed sample was measured at the exposed portion. Comparative Examples (Samples 101 and 102)
FIG. 1 shows the spectral absorption of the present invention (sample 105).

For the measured cyan dye, the maximum absorption wavelength of Comparative Example 1 was 566 nm, and the maximum absorption wavelength of Comparative Example 2 was 624 nm.
nm was 629 nm, whereas
In Comparative Example 1, the wavelength was increased to 63 nm, and in Comparative Example 2, the wavelength was increased to 5 nm.
The wavelength was increased to about nm. From this, it can be seen that the color separation is advantageous (for the magenta dye in the green photosensitive layer).

Example 2 The photosensitive materials 101 to 128 prepared in Example 1 and 40 ° C.8
What was stored for 7 days under the condition of 0% RH was treated with the following activator treatment solution at 38 ° C. for 30 seconds, and the same effect as in Example 1 was obtained. <Activator treatment solution> Sodium carbonate 26.5 g Sodium hydrogen carbonate 6.3 g Sodium sulfate 2.0 g Sodium bromide 1.0 g Water 1000 ml The pH was adjusted to 12 with an aqueous sodium hydroxide solution.

Example 3 A print sample was obtained after reading the image data of Examples 1 and 2 with a scanner and performing appropriate digital processing. The same result was obtained. It can be seen that the photosensitive material of the present invention is suitable as a photosensitive material for obtaining an image by reading with a scanner and performing digital processing.
