Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a silver halide color photographic material with improved color reproducibility, and more specifically, a silver halide color photographic material with reduced "abnormal coloring" of fabrics, etc. Regarding materials.

[Background of the invention]

In recent years, the image quality of color photographic materials has reached a very high level in terms of graininess, sharpness, and color reproducibility, but some inconveniences are still pointed out by users.

An example of this is ``abnormal coloring'' of fabrics, etc.

As mentioned in the 56th Photographic Paper Study Group Report in 1988, this is a phenomenon in which red appears in some parts of the clothing in photographs of people wearing gray clothing. This is a serious problem that we often hear not only from this report but also from commercial photographers. This is because, in order to avoid this phenomenon, you have to take the trouble to take the focus off and make the photo blurry.

Therefore, there is a strong desire for a means to solve the problem of abnormal color development without impairing the sharpness and color reproducibility inherent in color photographic materials.

[Object of the invention] The object of the present invention is to provide excellent sharpness and color reproducibility, and to
An object of the present invention is to provide a silver halide color photographic material in which "abnormal color development" is reduced.

[Structure of the invention]

As a result of extensive research into the above-mentioned "abnormal color development", the present inventors have discovered that this problem can be solved by using a silver halide color photographic light-sensitive material having the following structure, and have accomplished the present invention.

That is, an object of the present invention is to provide a silver halide color photographic material having at least one blue-sensitive, green-sensitive and red-sensitive silver halide emulsion layer, which satisfies both conditions (A) and (B) below. This is achieved by a silver halide color photographic light-sensitive material characterized by:

Condition (A) ATFG≧0.70 Condition (B) MTFG+0.20≦MTFa≦MTF
G-0,20 and MTFG+0.20≦MTFR≦MT
FG-0,20 However, MTFG, MTFG and MT
FG is 20 for blue-sensitive, green-sensitive, and red-sensitive emulsion layers, respectively.
Expresses the MTF value in lines/mm.

Note that the above condition (B) is MTFG+0.15≦MTFG≦MTFG−0,15 and MTFG+O,I5≦MTFR≦? ITF, -0,
In the case of a silver halide color photographic light-sensitive material of No. 15, it is a preferred embodiment because the effects of the present invention can be more fully expressed.

The present invention will be explained in more detail below.

When photographing a gray fabric woven with white and black threads,
When printing, a red color often appears on the fabric, which is a major problem for people involved in commercial photography, and various theories have been proposed regarding this phenomenon.

One theory is that it is a fabric that reflects red light that is invisible to the human eye. However, "abnormal color development" occurred even without such reflected light.

There is also a theory that this may be due to chromatic aberration of the lens. However, as a result of studies conducted by the inventors, it was found that this phenomenon cannot necessarily be explained by the chromatic aberration of the lens.

Therefore, as shown in the examples, MTF values (Modurat
ion Transfer Function), and created color films with various balances, photographed and printed fabrics woven in black and white, and found that only the film with the structure of the present invention was extremely sharp. It was also found that prints with reduced or no "abnormal color development" phenomenon could be obtained.

In order to set the MTF value of each coloring layer to the structure of the present invention,
Preference is given to using diffusible DIR compounds.

゛ In the present invention, a diffusible DIR compound refers to a development inhibitor or a compound capable of releasing a development inhibitor that is released by reaction with an oxidized product of a color developing agent, and has a diffusivity of 0.34 according to the evaluation method described below. It is preferably 0.40 or more.

A gelatin coating solution containing untreated silver iodobromide (silver iodide 2 mol%, average grain size 0.08 μm) was coated with a silver amount of 0.1 g/m2 and a gelatin coating amount of 0.8 g/m2.
Apply it so that it looks like this.

Sample (■): The same as the above sample (I) except that silver iodobromide was removed from the protective layer.

In addition to the above, each layer contains a gelatin hardening agent and a surfactant.

The sensitivity of sample (1) without the addition of a development inhibitor is S.

0i1-2 0i1-3 C-1 (2:3 mixture) Samples 102 to 109 obtained by changing sample 101 as shown in Table 1
It was created. These samples were exposed to white light in close contact with a wedge for measuring sharpness, then subjected to the development process described later, and the MTF values of the processed samples were measured using blue, green, and red light in a conventional manner. The MTF value of 20 lines/mm was determined for each.

On the other hand, using the above sample, a gray cloth woven with black and white threads was photographed and printed on Konica SR paper. Bleaching (〃
