Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a spectrally sensitized silver halide photographic light-sensitive material, and more specifically, it has excellent color reproducibility, particularly for blue-green color, and The present invention relates to a silver halide color photographic material that has excellent color reproducibility for light sources including fluorescent light sources.

[Background of the invention]

In recent years, the image quality of silver halide multilayer color photographic materials has significantly improved.

That is, in recent color photographic materials, the three major elements of image quality, namely graininess, sharpness, and color reproducibility, have all reached considerably high levels. For example, when it comes to general color photographs, it is believed that there are usually no major complaints regarding the color prints and slide photographs that users receive.

However, among the three factors mentioned above, in particular regarding color reproducibility, although color purity has improved, the situation has not changed much even today with respect to colors, which have traditionally been said to be difficult to reproduce in photographs. That is, there are still many deficiencies in hue reproducibility. For example, violet colors such as violet and blue-violet that reflect light with wavelengths longer than 600 nm, or green colors such as blue-green and yellow-green, will be reproduced as completely different colors from the actual colors, which will disappoint the user. Sometimes.

Spectral sensitivity distribution and interlayer effect (interimage effect, hereinafter referred to as 11E) are major factors related to color reproducibility.
There is.

Regarding IIE, the following is known. That is, it is known to add a compound that couples with the oxidized form of a color developing agent to form a development inhibitor or its precursor in a silver halide multilayer color photographic light-sensitive material, and from this so-called I) IR compound. It is known that by suppressing the development of other color-forming layers by the released development inhibitor, 11E is produced and the effect of improving color reproducibility is produced.

Furthermore, in a color negative film, it is possible to provide the same effect as IIE by using a colored coupler in an amount greater than the amount that offsets unnecessary absorption. However, when colored couplers are used extensively, the minimum density of the film increases, making it extremely difficult to judge color/density correction during printing, resulting in poor color quality in the resulting prints. occurs often.

Incidentally, these techniques particularly contribute to improving color purity among color reproducibility. The so-called diffusive DIR, in which the mobility of inhibitor groups and their precursors, which have been frequently used recently, is high, greatly contributes to the improvement of color purity. However, IIE has the drawback that it is difficult to control its directionality, and although it can achieve high color purity, it changes the hue. (Directional control of IIH is described in US Pat. No. 4,725,529, etc.).

On the other hand, regarding the spectral sensitivity distribution, US Patent No. 3,672.
No. 898 discloses an appropriate spectral sensitivity distribution for reducing variations in color reproducibility due to differences in light sources during photographing. However, this is not a means to improve the aforementioned poor color reproducibility.

In JP-A No. 61-34541, which also discloses a technology that combines spectral sensitivity distribution and IIE, an attempt has been made to improve the colors that are difficult to reproduce with the aforementioned color film, and some results have been achieved. It seems that it will be possible. A typical example of this is not only the conventional IIE from the center wavelength of each of the blue, green, and red sensitive layers, but also the IIE from a wavelength other than the center of gravity of each color-sensitive layer. .

This technology seems to be effective to some extent in improving the hue reproducibility of specific colors, but specifically, in order to express IIE, in addition to the original blue-sensitive, green-sensitive, and red-sensitive photosensitive layers, I
An IE expression layer and another type of photosensitive silver halide are required,
It has the disadvantage that production costs are high due to an increase in the amount of silver and an increase in the number of production steps.
Moreover, the effect could not be said to be sufficient.

For the above reasons, conventional silver halide color photographic materials have been insufficient in terms of color reproduction. In particular, it was difficult to faithfully reproduce blue-green colors, and the hues were sometimes far removed from the actual colors.

The present inventors focused particularly on this blue-green hue reproducibility, and as a result of intensive study, the spectral sensitivity distribution of the green-sensitive silver halide emulsion layer was shifted to the shorter wavelength side than before, and the wavelength λG giving the highest sensitivity was It has been discovered that the above-mentioned problems can be improved by designing the device so that max is 530 to 550 nm.

However, it has been found that even with the combination of the above techniques, only very unsatisfactory color reproducibility can be obtained when photographing under fluorescent lighting or under mixed light of strobe light and fluorescent light, which has become common these days. That is, if only a fluorescent light source or a strobe light is used, but there is an influence from the fluorescent light, the color reproduction will be greenish.

Furthermore, when the sensitivity at 560 to 570 nm becomes low, color reproducibility for orange and skin colors deteriorates. Therefore, it is also necessary to maintain spectral sensitivity in these wavelength ranges.

Furthermore, when spectrally sensitized with the sensitizing dyes used in the above techniques, storage stability under high temperature and high humidity conditions is not satisfactory, and improvement in storage stability has also been desired.

[Purpose of the invention]

An object of the present invention is to provide a silver halide color photographic material that has excellent color reproducibility, particularly for blue-green colors, and excellent color reproducibility for light sources including fluorescent lamp light sources.

[Structure of the invention]

In order to develop a silver halide photographic light-sensitive material that satisfies these demands, the present inventors have conducted intensive research and found that at least one blue-sensitive silver halide emulsion layer on a support,
In a silver halide photographic light-sensitive material having a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer, when measuring the reflection spectrum of the emulsion contained in at least one of the green-sensitive silver halide emulsion layers, At least two absorption maxima are observed, and at least one of the two absorption maxima is
The wavelength of at least one absorption maximum is 500 nm to 540 nm.
nm, and at least one absorption maximum wavelength is 540 nm.
It has been found that the above object can be achieved by a silver halide color light-sensitive material characterized by a wavelength range of 580 nm to 580 nm.

The objects of the present invention can be more effectively achieved when the emulsion contained in the green-sensitive silver halide emulsion layer satisfies either or both of the following requirements.

(a) Reflection density (OD1) of absorption maximum between 500 nm and 540 nm of the reflection spectrum of the emulsion contained in the green-sensitive silver halide emulsion layer and between 540 nm and 580 nm.
The ratio (OD1/O
D2) is 0.7 to 3.

(b) The sensitivity at the wavelength of absorption maximum between 500 nm and 540 nm of the reflection spectrum of the emulsion contained in the green-sensitive silver halide emulsion layer is 0.7 times to 4 times the sensitivity at the wavelength of absorption maximum between 540 nm and 580 nm. To be.

The present invention will be explained in more detail.

At least two absorption maxima in the reflection spectrum of the emulsion of the present invention are at least one between 500 nm and 540 nm, at least one between 540 nm and 580 nm, preferably between 510 nm and 540 nm and between 550 nm and 550 nm.
The wavelength is 570 nm.

The absorption maximum referred to here is obtained by a spectral sensitizing dye or a compound added for the purpose of spectral sensitization.

The emulsion of the present invention can be spectral sensitized with two or more spectral sensitizing dyes having an absorption maximum in the wavelength range defined by the present invention; It is also possible to add a spectral sensitizing dye having the following properties.

The absorption maximum when the spectral sensitizing dye used in the present invention is adsorbed alone on the same silver halide grains as used in the present invention may coincide with the absorption maximum in the emulsion of the present invention, but it may not coincide with the absorption maximum in the emulsion of the present invention. It's okay.

The emulsion of the present invention can also be prepared by mixing two or more types of emulsions having maximum absorption in each of the wavelength regions defined by the present invention.

Particularly preferred in the present invention is that the silver halide grains contained in the green-sensitive silver halide emulsion layer of the present invention are spectrally sensitized with at least three types of sensitizing dyes, and the reflection spectrum of the emulsion is measured. At least two of the absorption maxima that are sometimes observed are 5 times smaller than either of the absorption maxima of the reflection spectrum in an emulsion in which the sensitizing dye contained in the emulsion is solely adsorbed onto the silver halide grains. The present inventors have found that when such an emulsion is used and the layers are separated by m or more, the storage stability and sensitivity of the produced photographic material improves over time.

That is, the dye having the characteristic that the single absorption maximum wavelength in the emulsion of the dye represented by the general formula CI) according to the present invention is shifted by 5 layers or more when used in combination in the same emulsion system. is the only dye with excellent green light sensitivity according to the present invention.

In the present invention, the absorption maximum of the reflection spectrum of the emulsion of the present invention and the sensitizing dye represented by the general formula (1) contained in the emulsion are determined by the halogen composition and the same crystal habit as those contained in the emulsion. The absorption maxima of the reflection spectra of the emulsions adsorbed on silveride grains (hereinafter referred to as the absorption maxima of the dye alone) are separated by 5 nm or more, preferably 7 nm or more, and preferably 10 nm or more apart. More preferred.

In addition, the emulsion of the present invention may or may not have an absorption maximum at or near the absorption maximum wavelength of the dye alone, but it is preferable not to have it, and when such an emulsion is used, The present inventors have discovered that the storage stability of the produced photosensitive material over time is further improved. Note that the term "around the absorption maximum wavelength of the dye alone" as used herein refers to a wavelength range in which the difference from the absorption maximum wavelength is less than 5 nm.

In the present invention, the reflection spectrum of the emulsion is measured, for example, by the following method.

A coating solution is prepared by adding common photographic additives such as a surfactant and a hardening agent to the emulsion of the present invention, and the coating solution is coated onto a subbed triacetylcellulose support and dried to prepare a coating sample. do. The reflection spectrum of the sample can be measured using an ordinary spectrophotometer (for example, Hitachi Self-Recording Spectrophotometer Model U-3210 manufactured by Hitachi) equipped with an integrating sphere.

Further, the ratio of reflection density at absorption maximum of a green-sensitive silver halide emulsion can be determined, for example, as follows.

1) Separately prepare a sample by coating and drying a green sensitized emulsion on a transparent support, measure the reflection spectrum, and determine the relative optical density ratio of the absorption maximum. This method is
It can be used when a silver halide emulsion that has not been spectrally sensitized has no absorption at the absorption maximum wavelength.

2) A control coating sample is prepared using an emulsion that is not sensitized to green. The reflection spectra of the control sample and the sample of the present invention are each measured, the difference spectrum between the two is determined, and the ratio of the maximum absorption values is calculated from this.

In the present invention, 500nm to 540nm or 540n
When two or more absorption maxima exist in the wavelength range of m to 580 nm, the comparison in (a) or (b) above may be performed for the absorption maxima with higher reflection density in the absorption maxima.

In the present invention, the ratio of two absorption maximum reflection densities (OD+1
0D*) is preferably 0.7 to 3, but 0.
More preferably, it is 75-2.

A dye-forming coupler is used which reacts to form a dye. The dye-forming couplers are typically selected for each emulsion layer such that a dye is formed that absorbs light in the light-sensitive spectrum of the emulsion layer, with a yellow dye-forming coupler for the blue-sensitive emulsion layer and a dye for the green-sensitive emulsion layer. A magenta coupler is used in the sensitive emulsion layer, and a cyan dye-forming coupler is used in the red-sensitive emulsion layer. However, depending on the purpose, silver halide glass photographic light-sensitive materials may be produced using different combinations from the above combinations.

These dye-forming couplers preferably have a group called a ballast group in the molecule, which makes the coupler non-diffusive and has 8 or more carbon atoms. In addition, even if these dye-forming couplers are 4-equivalent, in which 4 molecules of silver ions need to be reduced in order to form 1 molecule of dye, only 2 molecules of silver ions need to be reduced. Either equivalence may be used. Dye-forming couplers include colored couplers that have a color correction effect and, by coupling with oxidized forms of developing agents, can be used as development inhibitors, development accelerators, bleaching accelerators, developers, silver halide solvents, and toning agents. Compounds that release photographically useful 7-ragments such as hardeners, fogging agents, antifoggants, chemical sensitizers, spectral sensitizers, and desensitizers are included. Among these, couplers that release a development inhibitor during development and improve image sharpness and image graininess are called DIR couplers. In place of the DIR coupler, a DIR compound which undergoes a coupling reaction with the oxidized form of the developing agent to produce a colorless compound and at the same time releases a development inhibitor may be used.

The DIR couplers and DIR compounds used include those with the inhibitor directly attached to the cambling position and those with the inhibitor attached at the cambring position.
It is bonded to the coupling position via a valence group, and the inhibitor is bonded in such a way that the inhibitor is released by an intramolecular nucleophilic reaction or an intramolecular electron transfer reaction within the system that is separated by the coupling reaction ( (referred to as timing DIR couplers and timing DIR compounds).

Also, depending on the purpose, inhibitors that can be dispersed after release and those that are not so dispersible can be used alone or in combination. Colorless couplers (also referred to as competitive couplers) that undergo a cambling reaction with the oxidized product of the aromatic primary amine developer but do not form dyes can be used in combination with dye-forming couplers.

The silver halide grains contained in the green-sensitive silver halide emulsion layer of the present invention, which is a particularly preferred embodiment of the present invention, are spectrally sensitized with at least three types of sensitizing dyes,
Any of the at least two absorption maxima observed when measuring the reflection spectrum of the emulsion is determined by the absorption of the reflection spectrum in the emulsion in which the sensitizing dye contained in the emulsion is solely adsorbed onto the silver halide grains. A compound that is released as a result of a reaction with an oxidized form of a developing agent of a development inhibitor or its precursor that can change into a compound with weak development inhibitory properties when the distance is 5 nm or more from any of the maximums (hereinafter referred to as
