Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, to a method that prevents deterioration of photographic properties due to harmful substances such as formaldehyde during storage of the light-sensitive material. This invention relates to silver halide color photographic materials.

[Conventional technology]

In general, an internal silver halide color photographic light-sensitive material has a plurality of silver halide emulsion layers that are sensitive to different regions of the spectrum and contain a coupler that reacts with the oxidation product of a color developing agent to form a dye. i.e. usually blue light,
It is composed of a silver halide emulsion layer that is sensitive to green light and red light and contains a yellow coupler, a magenta coupler, and a cyan coupler, respectively, on a support.

After exposure, yellow, magenta and cyan dye images are formed in each of these silver halide emulsion layers by color development.

In such a multilayer color photographic light-sensitive material, the best color image can be obtained only when each of the silver halide emulsion layers maintains a balance in terms of sensitivity and contrast.
It is desirable that the photographic properties of the photographic material remain unchanged even during a long storage period, including before and after exposure and before development. However, the inner mold containing the coupler/
``When a silver halide color photographic light-sensitive material is placed in a formaldehyde gas atmosphere before color development processing,
As the coupler reacts with formaldehyde and is consumed, it produces undesirable reaction products, such as reducing color density and gamma, causing color staining, or causing serious deterioration of photographic properties, such as increasing fog. bring about.

In recent years, as new building materials, furniture, resin products, adhesives, clothing, etc. that emit harmful gases such as formaldehyde have come into widespread use in daily life, the opportunities for photographic materials to come into contact with these harmful gases have increased. ing.

In order to prevent such deterioration of photographic properties due to reaction with formaldehyde, it has been proposed to use, for example, a compound that is reactive with aldehyde and renders it harmless (hereinafter referred to as an aldehyde scavenger). There is.

-For example, U.S. Pat. No. 2,309.492 states:
Pointed out the problem of trace amounts of formaldehyde, which interacts with pyrazolone color formers to form yellow compounds and cause color fog in photographic elements, and the use of hydroxylamine, hydrazine derivatives, hydrazo derivatives, momicarbazide, dimethylhydroresorcinol, or naphthylenediamine. suggest the use of aldehyde scavengers such as Also, US Patent 2,
No. 895,827 shows the problem of formaldehyde from photographic paper supports coated with aldehyde resins such as urea-formaldehyde and melamine-formaldehyde, and shows that urea on the surface of such supports acts as an aldehyde scavenger. Alternatively, the use of a melamine sizing layer is proposed.

Furthermore, Japanese Patent Publication No. 46-34675 discloses that N is used as a scavenger for formaldehyde gas contained in the atmosphere.

N'-ethylene urea, 2,3-dihydroxynaphthalene, dimedone, etc. are proposed.

Further, US Pat. No. 4,414.309 proposes the use of iminopyrazolone compounds.

However, since these compounds do not have sufficient ability to capture aldehyde gas, the addition of these compounds alone cannot satisfactorily prevent the deterioration of photographic performance that is currently a problem.

Furthermore, adding a large amount of aldehyde scavenger has the disadvantage of deteriorating the physical properties of the film of the photosensitive material, such as brittleness of the coating, and also has a negative effect on the photographic properties itself, so the amount of aldehyde scavenger added may also be affected. There are limits of course.

On the other hand, regarding the relationship between the above harmful gases and couplers, although deterioration of photographic performance due to harmful gases appears when using any coupler, it is especially true for so-called couplers in which no substituent is introduced into the active site in the molecule. It has been found that the effect is remarkable in the case of 4-equivalent couplers, and that both yellow and magenta couplers are more easily affected than cyan couplers, with magenta couplers being particularly affected most strongly.

The present inventors investigated the reactivity of 5-pyrazolone 4-equivalent coupler, which is the most common magenta coupler, with formaldehyde gas, but were unable to find a coupler that could significantly improve the deterioration of photographic performance. Ta. On the other hand, it is known that by increasing the ratio of high-boiling organic solvents that are immiscible with water to oil-soluble couplers, the effects of harmful gases such as formaldehyde gas can be further reduced, but this improvement is not sufficient. .

On the other hand, increasing the proportion of the high boiling point organic solvent may cause various problems, such as problems with the physical properties of the film, and for this reason there is a limit to how high the proportion can be increased.

On the other hand, in recent years, various magenta couplers have been reported that have low reactivity to harmful gases such as formaldehyde, in other words, are highly resistant. For example, U.S. Patent 3.2
No. 14437, No. 3,253.924, No. 3゜311
．． No. 476, No. 3,419,391, No. 3,617.
No. 291, No. 3゜926.631, No. 3,522,0
No. 52, No. 3,227.554, JP-A-56-126
No. 833, etc., describe a 2-equivalent coupler as an example of such a coupler.

However, even when a 2-equivalent coupler as described above is used, the influence of harmful gases such as formaldehyde is much smaller than that of a 4-equivalent coupler, but this does not mean that it is not affected at all. Therefore, even if the coupler used is changed to a C1 coupler that is highly resistant to harmful gases such as formaldehyde, the reality is that an aldehyde scavenger is still essential.

[Purpose of the invention]

Therefore, the purpose of the present invention is to improve photographic properties such as a decrease in color density and gamma, occurrence of color contamination, and increase in fog even if exposed to harmful gases such as formaldehyde for a long period of time during storage before color development processing.

The silver halide grains used in the silver halide emulsion may have a uniform silver halide composition distribution within the grain, or may be core/shell grains in which the silver halide composition differs between the inside and surface layer of the grain. .

The silver halide grains may be grains in which a latent image is mainly formed on the surface, or grains in which a latent image is mainly formed inside the grain.

Silver halide emulsions having any grain size distribution may be used. An emulsion with a wide grain size distribution (referred to as a polydisperse emulsion) may be used, or an emulsion with a narrow grain size distribution (referred to as a monodisperse emulsion) may be used alone or in combination. Further, a mixture of a polydisperse emulsion and a monodisperse emulsion may be used.

The silver halide emulsion may be a mixture of two or more separately formed silver halide emulsions.

The emulsion can be chemically sensitized by conventional methods, or optically sensitized to a desired wavelength range using a sensitizing dye.

Antifoggants, stabilizers, etc. can be added to the silver halide emulsion. Gelatin is advantageously used as binder for the emulsion.

As the magenta dye-forming coupler, 5-pyrazolone couplers, pyrazoloazole couplers, pyrazolopenzimidazole couplers, open-chain acylacetonitrile couplers, indazole couplers, etc. can be used, but in the present invention, 4 equivalents of 5-pyrazolone couplers are used. When a coupler is used, it is particularly effective for applications.

Phenol or naphthol couplers are commonly used as cyan dye-forming couplers.

A light-sensitive material may be provided with auxiliary layers such as a filter layer, an anti-halation layer, an anti-irradiation layer, etc. In one of these layers and/or in an emulsion layer, there are substances that may flow out of the light-sensitive material during development processing, or Alternatively, it may contain a bleaching dye.

A matting agent, a lubricant, an image stabilizer, an ultraviolet absorber, an optical brightener, a surfactant, a development accelerator, a development retardant, and a bleach accelerator can be added to the photosensitive material.
