Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide light-sensitive material, and
The present invention relates to a silver halide photosensitive material having excellent sharpness.

[0002]

2. Description of the Related Art Conventionally, a silver halide photosensitive material (hereinafter, referred to as a "silver halide photosensitive material")
Abbreviated as "photosensitive material". The recent technological advancement in ()) is remarkable. Until now, of course, demands for improving photographic performance such as the image quality of the photosensitive material itself,
Recently, various types of cameras, such as a film with a lens, are often used for photographing, and there is a demand for a photosensitive material that can be clearly photographed even when photographed by an inexpensive camera.

[0003] Flare is one of the degradations in image quality when photographed with an inexpensive camera such as a film with a lens. Flare is a phenomenon in which light incident on the camera is blurred or blurred due to scattering of reflected light on the camera lens, the camera, and the film surface. In order to reduce flare, a camera is coated on a lens or the like to prevent light scattering, but it is difficult in terms of cost.

On the other hand, on the side of the photosensitive material, it has been practiced to reduce the reflectance of the film surface by adding a dye or the like to reduce the reflected light itself. .

In recent years, the use of photosensitive materials has been increasing in that images such as photographs are scanned, converted into image data, processed by a computer, and output to the photosensitive material again. In this case, a digital film recorder (film writer) is generally used as a device for outputting to a photosensitive material. Digital film recorders (hereinafter abbreviated as DFRs) mainly have two exposure systems.
One is a CRT exposure method, and the other is an exposure method using a laser or LED. A major cause of image quality degradation during exposure by such DFR is flare. Flare in the case of DFR is a phenomenon in which light in a portion having a high exposure intensity is reflected and scattered in the apparatus, and the other portion is blurred. In order to prevent such flare, in the case of the CRT exposure method, the glass on the front surface of the CRT is thickened or colored, but this is not sufficient. Further, in the case of the laser or LED exposure method, it is necessary to take measures on the photosensitive material side because there is little flare problem in the exposure apparatus.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to reduce flare even when photographed by an inexpensive camera, and
An object of the present invention is to provide a silver halide light-sensitive material excellent in sharpness and having less light bleeding (flare) even when exposed by a digital film recorder.

[0007] As a result of various studies, the present inventors have found a silver halide light-sensitive material which has reduced flare without lowering the sensitivity and has high sharpness.

For the sample 101, the AI-
Sample No. 1 was prepared by adding 0.01 g, 0.02 g of AI-2, and 0.03 g of AI-3. Sample 103 was prepared by replacing the silver iodide emulsion E of the fifteenth layer of the sample 101 with the emulsion F, and keeping the added amount. Further, Sample 104 was prepared by replacing the silver iodide emulsion E of the fifteenth layer of Sample 101 with Emulsion G and keeping the added amount. Further, the alkali-soluble matting agent in the 17th layer of sample 104 was replaced with P-2,
It was created.

For each of the obtained samples, refer to JP-A-8-179460.
The specific photographic sensitivity was determined by the method described in Japanese Patent Application Publication No. In addition, a test pattern exposure for sharpness (MTF) evaluation is given,
Sharpness was determined by performing C-41 treatment manufactured by Eastman Kodak Co. described in British Journal of Photograpy 1988, pp. 196-198. The effect of improving the sharpness is based on the MTF (Modu
MTF at 30 / mm
(Sample 101 is taken as 100).

The specular reflectance (SR) of each sample was measured using C
The reflectance (SCI) including specular reflection light and the reflectance (SCE) after removing regular reflection were measured with M-2002, and the difference between the reflectance containing specular reflection light at 550 nm and the removed reflectance was indicated by%. .

Further, each sample was cut into 135 size standards, stored in a patrone, and loaded into the photographing unit shown in FIG. 1 in which the photographing unit body was placed in a carton.
We photographed the person outdoors in semi-backlit. Using the Konica minilab system NPS-858J Type II, the photographed sample was used as a developing agent CNK for Konica color negative film.
The film was developed by 4-41-J1 and dried to obtain a film sample having a color negative image. Further, printing was performed on Konica Color Paper Type QAA6 to obtain a print. The resulting prints were visually evaluated for flare appearance.

The sample cut into a 135 size standard and stored in a patrone was exposed to image data having a high luminance ratio using a digital film recorder Opal manufactured by MGI, and subjected to the same development processing as described above. Each of the obtained developed samples was visually evaluated for flare appearance.
(DFR1) Digital film recorder Lite manufactured by MGI
The same evaluation was performed for jet. (DFR2)

Evaluation of flare ：: Flare is not generated. フ レ: Flare is hardly generated. Δ: Flare is slightly generated but does not affect the image. X: Flare is generated and affects the image. XX: Flare is severely generated and greatly affects the image. The results are shown in Table 2.
