Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material, and particularly to a silver halide color photographic light-sensitive material for photographing with excellent graininess.

(Prior Art) Over the past few years, with the spread of small-format cameras, small-screen color negatives have often been enlarged to large-screen color prints.

There is a growing demand for better graininess and resolution than ever before.

Among these, K is T, I (.

d, increasing the number of silver halide grains as described in PJco0~Pt2/, and color printing 1
This can be improved by obscuring the pigment produced by the image. However, K, which increases the number of silver halide grains while maintaining the 1c sensitivity, increases the amount of coated silver and thereby causes deterioration of the solution f[, which is disadvantageous in terms of cost, Aff, and performance.

Further, an attempt to improve the graininess by diffusion of a dye is described in British Patent No. 20104 Hiro 117A.

Although the use of so-called dye-diffusing couplers improves the RMS graininess, as mentioned above, this method gives a visually unpleasant feeling.

We have been conducting research on improving graininess for some time and have discovered the following. When using a non-diffusive coupler (hereinafter simply referred to as a dye-diffusing coupler) that produces a diffusible dye with appropriate dye bleeding as a means of improving graininess, so-called r (MS granularity (RMS granularity is T),
E-1, James.

”Theory of the Photographer
aphicProcess" (described in the μth edition PAD?) is greatly improved. However, the arrangement of silver halide grains and the development probability occur in a random process.

When the pigments diffuse and mix with adjacent pigments, the overlap between one pigment cloud increases, and as a result, huge pigment clouds are randomly generated. This is visually very unpleasant and may even make the grain look worse.

As a means to improve this visual grain deterioration.

It couples with the oxidized form of a color developing agent to release a development inhibitor or a development inhibitor precursor.

By adding so-called DIR compounds fJ≦.

JP-A-Sho has discovered a method to prevent the formation of huge pigment clouds! r−λ/
In this case, the formation of a dye cloud from a single dye diffusive coupler by development and the DI
Since the development inhibitory effect of the R compound proceeds at the same time, it cannot be said to be perfect from the viewpoint of preventing the formation of a huge dye cloud.

Furthermore, the addition of the DIR compound Vi, and at the same time its development inhibiting effect, inevitably leads to a decrease in the sensitivity and the maximum g
This results in a decrease of 1 degree, and in order to compensate for this, the coating tt of the coating material must be increased, such as 4t4, resulting in a decrease in sharpness.

(Objective of the Invention) The object of the present invention is to provide a silver halide color light-sensitive material which has improved the above-mentioned drawbacks, and specifically, to improve visual graininess, daylight sensitivity, and high maximum madder ρ. The object of the present invention is to provide a color photosensitive material that simultaneously achieves the following functions.

(Bottom of the Invention) An object of the present invention is to contain a diffusion-resistant coupler (diffusible dye-forming coupler) that reacts with the oxidation product of a color-developing agent to produce a diffusible dye that causes appropriate dye bleeding. At least one silver halide emulsion I? 4 and adjacent to this layer,
and a compound that reacts with the oxidized product of the color developing agent to form a diffusible development inhibitor or development inhibitor precursor (
This is achieved by a silver halide color light-sensitive material having at least one non-light-sensitive layer containing a diffusive DIR compound on the entire support. It has been found that, according to the present invention, it is possible to provide a color photographic material that eliminates the above-mentioned visual discomfort and has excellent graininess both visually and in terms of rLMS graininess.

In other words, as described in JP-A-5-17-32, when a diffusive dye-forming coupler is used, the amount of dye in each dye cloud remains the same and the dye diffuses to the surrounding area, resulting in a single color patch. Since the n+7& distribution in the dark is small and has a large area (hereinafter referred to as a diffuse color Jmo cloud), improved numerical values can be obtained if the graininess is expressed using a so-called RMS value. However, as mentioned above, because the pigment cloud becomes larger.

The pigment clouds overlap each other, and the so-called venus is called kutor (Th
e Theory of PhotographicP
rocess' ttth Ed. The lower this value is, the better the 1 grain size is).

Visually, this means that some pigment clouds have solidified and large mottles are visible. When a dye-diffusing coupler is used, even though the RMS value of graininess is improved, it gives a visually extremely unpleasant feeling, indicating that the graininess is misleading. become.

In such a system, a non-photosensitive interlayer gold film is placed in contact with the ridge containing the diffusible pigment-forming coupler, and a diffusible color suppressor or a diffused pouring precursor is added in this layer. Released by ring reaction. There are all DIR compounds.

By considering 8 released from the DIR compound, the timing of the development inhibiting effect of the inhibitor is delayed, and the formation of the aforementioned giant dye cloud can be extremely efficiently prevented. the result.

Because the size distribution of the diffuse color cloud is narrower, and therefore there is less overlap between large dye clouds, the diffusive dye-forming coupler and the DIR coupler can all be placed in the same emulsion layer.
In the case of r-J/7 R3, the value of the Winners vector in the low frequency part is effectively reduced, that is, visually large mottles are no longer noticeable, and visual graininess is improved.

J to 6-membered heterocyclic nuclei such as 11 μm dione nucleus, thiazolidine-J, 4C-dione nucleus, rhodanine nucleus, and thiobarbic acid nucleus can be applied.

These sensitizing dyes may be used alone or in combination, and combinations of sensitizing dyes are often used particularly for the purpose of one-strong color sensitization.

Along with the sensitizing dye, it is a dye that itself does not have a spectral sensitizing effect or a substance that does not substantially absorb visible light,
The emulsion may contain a compound 'R exhibiting supersensitization.

The invention is also applicable to multilayer, multicolor photographic materials having at least one different degree of density on the support. Multilayer natural color photographic materials usually contain a red-sensitive emulsion rc1. on a support. It has at least one green-sensitive emulsion layer and at least one blue-sensitive emulsion layer. The order of these layers can be arbitrarily selected as required. Usually, the red-sensitive emulsion layer contains a cyan-forming coupler, the green-sensitive emulsion layer contains a magenta-forming coupler t, and the ff'-sensitive emulsion layer contains a yellow-forming coupler 1, but different combinations may be used depending on the case.

The photographic emulsion layer or non-photosensitive iK of the photographic light-sensitive material made using the present invention contains a dye-forming coupler, ie.

In the color development process, a compound capable of developing color by oxidative coupling with an aromatic primary amine developer (eg, phenylene diamine derivative, amine phenol derivative, etc.) may also be used.

For example, magenta couplers include j-pyrazolone couplers and pyrazolobenzimidazole couplers.

There are pyrazolotriacye, lucupar, cyanoacetylcoumarone coupler, open-chain acylacetonitrile coupler, and Yemi couplers include afuracetamido coupler (91, t is benzoylacetanilide, pivaloylacetanilide nail 1), etc. Examples of cyan couplers include naphthol couplers and phenol couplers. These couplers are preferably non-diffusible and have a hydrophobic group called a ballast group in their molecules, or are polymerized. The coupler may be either Buddha-equivalent or co-equivalent to the @ ion.

It may also be a colored coupler that has a sound effect for one-color correction, or a coupler that releases a development inhibitor during development (so-called DIR coupler).

Furthermore, in the present application, the diffusive DIR compound can be used not only in the non-photosensitive layer according to the present invention, but also in other photosensitive layers and intermediate layers. The layers do not need to be colored in the same hue.

In addition, other than the DIRIn coupler, the product of the coupling reaction is colorless, and the colorless DI that releases the current inhibitor is used.
The R coupling compound may also contain gold.

1) In addition to the In coupler, a compound 'f that releases a development inhibitor during development may be used as a photosensitive material.

Are the above couplers etc. custom-made required for photosensitive materials? In order to satisfy the requirements, two or more types V can be used together in the same layer, or the same compound can be added to two or more different layers.
Of course it doesn't matter.

The photographic color formers used are conveniently selected to provide intermediate scale self-cleaning. The maximum absorption band of the cyan dye formed from the cyan color former is about 6 QO to 7 QO
The maximum absorption band of the magenta dye formed from the magenta color former is between about SOO and Jronm, and the maximum absorption band of the yellow dye formed from the yellow color former is about lto.

and jronm is preferred.

The sample /Q/~ioμ was processed into llO size and all practical photographs were taken, and then it was printed to cabinet size and psychological evaluation of graininess was performed.

Furthermore, regarding the graininess of magenta color 1 of samples i0i to 104A, Winers vector r '641 constant aperture μlO
μ) was calculated.

Of the above, the results of I' (MS graininess value and psychological evaluation are summarized in Table/K).

Table-/Vi, sample lθ using diffusive color chart forming coupler
Compared to JVi and Sample/Ql, the RMS graininess value shows that the graininess is improved.

However, 2-visual KVi shows that the huge color cloud is conspicuous, and the 1-grain shape looks rather rough. Also.

Adding a diffusible DIR coupler to an adjacent layer of a dove with a non-diffusible dye-forming coupler (10 samples) has a small effect on both RMS graininess and visual graininess.

In contrast, a sample in which the diffusive DIR coupler gold was added to the layer adjacent to the layer using the diffusion-coloring purple-forming coupler (sample 104)
In L), not only the RMS granularity value but also the visual granularity was significantly improved, and the effect of the present invention is clear.

The above results can be explained by looking at the Winers vector (gt diagram).

Figure 414/ is a sample using a diffusive color patch forming coupler, and the spectrum of sample/Q3) has a larger upward trend at frequencies lower than IQ cycles/l.

It is shown that large unevenness is easily noticeable in sample 1O3.

In a sample using a 7INK diffusion injection DIR coupler that momentarily contacts this AK (sample 10g), its spectrum Fi,
It is located lower than any of the samples H/Q/~103 over the entire area, which is consistent with the fact that psychological and visual graininess is clearly visible.

(Sample 1oa) Sample 20 was prepared in the same manner as Vi sample 20 except that 65 equimolar amounts of coupler C-Q- and coupler EX-1 were added instead of coupler EX-co in the first A layer of sample 0λ.

The obtained sample was wet exposed to 20/-λOμ total white light,
The treated sample was treated in the same manner as in Example 1.
The MS value and Guiners vector were determined, and psychological evaluation of graininess was also performed.From Table 2, fc sample 203 using a 1-dye diffusion type coupler has a higher R than sample λQ/Ji.
Looking at the MS granularity value, the 1 granularity has been improved, but visually the Vc bottle is still a little noticeable with large unevenness.

In addition, in sample λQ, only a slight improvement effect was observed in both RMS feed and visual graininess compared to sample 0/.

On the other hand, in Sample 20, it is clear that both the R8 (SIII!) and the visual graininess are significantly improved.

These results are also explained in the Guiners vector (Q 2 +71).

The spectrum of sample 2.03 has a sudden upward trend at a low frequency of IQ cycle/parrot.

This indicates that large insects are easily visible.

The spectra of sample λ04A are lower than those of samples KOQ/ and -KO03 over the entire range, which is consistent with the fact that graininess appears psychologically and visually. do.
