Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a color reversal image forming method with improved interimage effect (multilayer effect) and improved sharpness and graininess.

(Prior art) By color-developing a silver halide color photographic light-sensitive material, the oxidized aromatic-amine color developing agent and coupler react to produce indophenol, indoaniline, indamine, azomethine, and phenoxazine. , phenazine and similar dyes are known to form color images. In this system, subtractive color reproduction is usually used for color reproduction, with silver halide emulsions selectively sensitive to blue, green, and red, and yellow, magenta, and cyan color image-forming agents, which are complementary colors, respectively. is used. To form a yellow image, for example, an acylacetanilide or dibenzoylmethane coupler is used, and to form a magenta image, a pyrazolone is mainly used.

Pyrazolobenzimidazole, pyrazolopyrazole, pyrazolotriazole, cyanoacetophenone or indacylon couplers are used, with phenolics or naphthols being primarily used to form cyan images.

By the way, the dyes produced from these couplers do not have ideal spectral absorption spectra; magenta and cyan dyes in particular have broad absorption spectra or have sub-absorption in the short wavelength region, which makes color photographic materials difficult to use. Unfavorable for color reproduction.

In particular, sub-absorption in the short wavelength region tends to cause a decrease in chroma. One way to improve this is to create an interimage effect.

Regarding the interimage effect, see, for example, Hanson (

Regarding the interimage effect of a color reversal image forming method, U.S. Pat. By containing silver halide grains capable of forming a latent image in another layer, and silver halide grains whose surface is covered with a film that develops independently of image exposure. , a method to obtain a good interimage effect is described.

On the other hand, higher image quality is desired for halogen color reversal photosensitive materials. Among these, graininess is very important, and achieving high sensitivity with a fine-grain silver halide emulsion is very effective in improving graininess.

A great deal of research has been done to improve graininess.

One of them is Japanese Patent Application Laid-open No. 60-107029, in which a silver halide photographic light-sensitive material containing a compound that releases a fogging agent under alkaline conditions through a redox reaction with an oxidized developer during development achieves high contrast. , techniques for achieving effects such as rapid processing and increased sensitivity have been disclosed.

Furthermore, in JP-A-60-153039, at least one compound that releases a fogging agent, a development accelerator, or a precursor thereof during development of a silver halide light-sensitive material (particularly a color negative light-sensitive material) and an antifoggant are disclosed. It is disclosed that when used in combination, sensitivity can be increased without increasing fog.

(Problems to be Solved by the Invention) However, the method described in the above-mentioned US Pat. No. 4,082,553 has major drawbacks such as deterioration of graininess and reduction in color density.

Also, JP-A-60-1070279, JP-A No. 80-1530
When the method described in No. 39 is applied to a color reversal photosensitive material, the graininess is improved, but when the unexposed film is stored for a long period of time, or even for a short period of time at a high temperature, an undesirable decrease in maximum density occurs. There was the problem of inviting the

A third object of the present invention is to provide a color reversal image forming method that achieves high sensitivity without impairing other photographic properties.

The processing of the color reversal photosensitive material of the present invention usually involves black and white development (first development) → stop → water washing → reversal → water washing → color development →
Stop → Wash with water → Conditioning bath → Wash with water → Bleach → Wash with water → Fix → Wash with water →
A stabilization→drying step is used. This step may further include a prebath, a predural bath, a neutralization bath, etc.
Stop 1 Reversal, color development, conditioning bath, or washing with water after bleaching may be omitted.0 Reversal may be performed in a fogging bath or may be performed by re-exposure, and the fogging agent may be used for color development. It can also be omitted by adding it to the bath. Furthermore, the adjustment bath can also be omitted.

Known developing agents can be used in the first developer used in the present invention. Examples of developing agents include dihydroxybenzenes (eg, hydroquinone), 3-pyrazolidones (eg, 1-phenyl-3-pyrazolidone), and aminophenols (eg, N-methyl-p-aminophenol).

The first developing solution used in the present invention must contain a compound that acts as a silver halide solvent, but the sulfite added as a preservative as described above usually plays this role. Specifically, the vine silver halide solvent used is KSCN, Na5CN, 2So3, Na2SO3, K2S2O5, Na2S2O5, K
Examples include SO, Na2S2O3, and the like.

If the amount of these silver halide solvents used is too small, the progress of development will be slowed down, and if it is too large, the silver halide emulsion will become foggy, so there is a preferable amount to use, but it is difficult to determine the amount. is easily accomplished by a person skilled in the art.

For example, when using 5CN-, one developer per sight o, oo
It is preferably from s to 0.02 mol, particularly from 0.01 to 0.015 mol, and when using 5o32-, 0.0

The pH value of the developer thus adjusted is selected to be sufficient to provide the desired density and contrast;
Desirably, it ranges from about 8.5 to about 11.5.

In order to carry out sensitization processing using such a first developer, it is usually sufficient to extend the time up to about three times as long as the standard processing time. If the treatment temperature is raised at this time, the extension time for the sensitization treatment can be shortened.
