Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide color light-sensitive material, and more particularly to a silver halide color light-sensitive material with improved sharpness.

[Background of the invention]

In general, a silver halide color photographic light-sensitive material (hereinafter sometimes simply referred to as a light-sensitive material) generally includes a red-sensitive/'-silver halide emulsion layer containing a cyan coupler on a support,
It has a green-sensitive silver halide emulsion layer containing a magenta color-forming coupler and a blue-sensitive silver halide emulsion layer containing a yellow color-forming coupler, as well as an antihalation layer as required.
It has an intermediate layer, a filter layer, a protective layer, etc.

With regard to recent photosensitive materials, on the one hand, users' demands for image quality have increased, and on the other hand, there has been an increase in the use of small 7-ohm formats. For this reason, images of higher quality than ever before are desired, and many efforts have been made to achieve this goal.

In order to improve the sharpness, studies have been made from both optical and development effects.

From an optical perspective, the grain size of the silver halide emulsion that scatters light can be controlled by using a monodisperse silver halide emulsion.
It is known to reduce the total weight of the photosensitive silver halide emulsion to less than lOg/m'' (Agj converted value).

Further, as mentioned above, from the viewpoint of shortening the scattering path of light, thinning of the photographic constituent layers has been studied.

In particular, in the case of a silver halide emulsion layer that is closer to the support, the scattering path of light from the surface of the light-sensitive material becomes longer, so it is known that thinning the film by reducing the amount of binder is an effective means of improving sharpness. . (For example, Journal of
The Optical Society 4-of America (J
internal of the 0ptical Soci
ety of America) 58 (9), 12
45-1256 (196g), Photographic Science and Engineering (Photogr
aphic 5science and Engineering
ering) 16(3), 181-191(197
2) etc.).

Furthermore, as specific means for this purpose, there are known methods such as simply reducing the amount of gelatin coated, reducing the amount of coater coated, reducing the amount of high boiling point solvent for coupler dispersion, and using a so-called polymer coater.

In order to improve sharpness, the polymer coupler technology described in Japanese Patent Application Laid-Open No. 58-28745, etc. or Japanese Patent Application No. 1-195
234, etc., it has become possible to reduce Oi by 1 minute or Gel and achieve thin films.

On the other hand, as a method to improve sharpness from the viewpoint of development effect,
JP-A-59-131934, JP-A-57-154
A method using a diffusible DIR compound is known in Japanese Patent Publication No. 234 or Japanese Patent Publication No. 61-27738.

However, when the photographic constituent layers are thinned by the above method, color smearing occurs between emulsion layers with different color hues, film strength decreases, and furthermore, pressure resistance decreases and the formed It may cause damage to the photographic image,
It became clear that this was not a completely satisfactory method.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a silver halide color light-sensitive material with improved sharpness without decreasing film strength or pressure resistance.

However, for samples 101°, 102°, and 105, the coupler was added by a conventional oil-in-ice dispersion method using a high-boiling point solvent, a so-called oil-protected dispersion method.

For samples 103 and 104, the couplers used in each photosensitive layer were dispersed as follows.

Couplers used in each emulsion layer Colored coupler DIR compound, SC-1 was dissolved in n-propanol in an amount 4 times the amount (weight) of the coupler and 1.5 times the amount of 33% aerosol 102 aqueous solution at 65°C. The mixture was supplied at 20 mQ/win to a dispersion machine containing 30 times the amount of water as the coupler, and stirred vigorously. At this time, the dispersion liquid was maintained at 40°C.

The solvent was removed from the dispersion continuously using a semipermeable membrane to obtain a dispersion.

Therefore, each photosensitive layer of samples 103, 104, i.e., layers 3, 4, 6, 7, 9, 10, is coated with a high boiling point solvent. After exposure for sensitometry, development was performed.

However, the development process was carried out as follows.

The sharpness was evaluated as follows.

After exposing to white light using a sharpness evaluation filter and developing the dye image, the M TF (Moduration
nTransfer Function) was determined. Table 2 shows the relative values of MTF at 20 lines/mm and 60 lines/mm. However, the MTF value of No. 101 is set to 100.
And so.

The pressure resistance was evaluated as follows.

JIS K6718 standard product sapphire needle (
0,025+nm-), the sample was then developed as described above, and after drying, the transmission density of the scratched area was measured using a Konica microdensitometer model PDM-5. Relative evaluation was performed based on sample 101.

Evaluation of coating film strength was performed as follows.

Regarding the coating strength, each sample was tested with a width of 3-5 cm and a length of 14 cm.
After cutting it into pieces of 5 m in size and immersing them in the color developing solution at 38°C for 3 minutes and 15 seconds, they were crimped onto the film surface using a needle equipped with a stainless steel pole with a diameter of 0 to 5 mm at the tip.
Continuously change the load on the needle while moving at a speed of m/sec, and calculate the load (g) at which the membrane breaks (scratches occur).
).

The evaluation results of sharpness, pressure resistance, and coating film strength are summarized in Table 2. However, regarding sharpness, magenta images were measured using green light. Pressure resistance was evaluated based on the following criteria.

◎...Excellent, no problems at all.

O: There is no practical problem, but defects are observed.

△...There are some problems, but it is usable.

×...It is a problem and cannot be put into practical use.

Table 2 As is clear from Table 2, the structure of the present invention not only improves sharpness, but also improves pressure resistance and coating strength without deteriorating them. .

[Example-2] The 811 layers of sample 104 in Example-■ were divided into two,
A layer corresponding to the 11th layer of sample 101 with Em-5 removed (IIA layer), and a gelatin layer (11 layers) containing Em-5 in the same coating amount and having a dry film thickness of 1.25 μm.
The IIA layer, the 118th layer, and the 12th layer are placed on the 10th layer in this order.
A sample 201 was prepared with a three-layer structure.

As a result of evaluation in the same manner as in Example-1, both pressure resistance and coating strength were superior to Sample 104.

[Example-3] In preparing the coupler dispersions of each color-sensitive layer of Samples 103 and 104 in Example-1, they were moistened with an aqueous solution of Aerosol 102 without using n-propatool, and then wetted with a sand mill (Shinmaru Enterprises Co., Ltd.). A dispersion liquid was obtained by dispersing with a Dyno Mill (manufactured by Co., Ltd.).

Samples 301.302 corresponding to samples 103.104 were prepared in the same manner as in Example-1.

When the sharpness, pressure resistance, and coating strength were evaluated in the same manner as in Example 1, almost the same results as Samples 103 and 104 were obtained.
