Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material. It relates to a silver halide color photographic material.

[0002]

2. Description of the Related Art In recent years, in the photographic processing service industry, there has been a demand for high-quality photographic light-sensitive materials that can be processed quickly as part of improving services to users and as a means of improving productivity. In order to meet this demand, a photographic light-sensitive material containing a high silver chloride emulsion (hereinafter sometimes referred to as a "high silver chloride print material") is processed with a color development time of 45 seconds, and from the start of the development step. Rapid processing is generally performed in which the total processing time until the drying step is completed is about 4 minutes (for example, color processing CP-48S manufactured by Fuji Photo Film Co., Ltd.).

[0003] However, when compared with the speed of image production of other color image production systems (for example, electrostatic transfer system, thermal transfer system, ink jet system), even this rapid development processing system for high silver chloride print materials is still satisfactory. It is hard to say that it is very quick, and ultra-rapid processing is desired in which the total processing time from the start of development to the end of drying of a high silver chloride color print material is less than 1 minute.

[0004] To this end, various investigations and efforts have been made in the art for means for improving suitability for ultra-rapid operation. For example, as a means of improving the suitability for ultra-rapid processing, the amount of the organic material to be applied can be reduced by employing a highly active coupler or a coupler having a large molecular extinction coefficient of the coloring dye, and the amount of the hydrophilic binder to be applied is reduced, and the developing speed is high. The use of silver halide emulsions is being studied. Also, a method is known in which a silver halide emulsion layer having the slowest developing speed (a layer containing a yellow coupler in a conventional color print material is applied) on the side far from the support to speed up development. For example, JP-A-7-239538 and JP-A-7-2
No. 39539.

[0005] However, rapid development processing is often accompanied by a reduction in image quality, and this is a great limitation particularly when achieving ultra-rapid development. In particular, a decrease in image quality due to ultra-high speed is a decrease in whiteness of a highlight portion. Causes of the decrease in whiteness include an increase in fog due to an increase in development activity, and a minimum density value due to coloring (called residual color) that occurs when a part of the sensitizing dye in the photosensitive material remains in an image after development processing. (Dmin), poor desilvering, coloring of a white portion of an image due to a residue in the photosensitive material, and the like. The degree of whiteness greatly depends on the viewing light source dependence.

[0006] Vigorous studies in the art have been made on solutions to the defects associated with these ultra-rapid development processes. Examples of a method for suppressing fog and residual color and obtaining a low-density Dmin include the methods described in JP-A-6-39936, JP-A-6-59421, and JP-A-6-202291. As a method for suppressing this, for example, JP-A-7-140625 and JP-A-5-341
No. 470, etc., as a method for reducing residual color, use of a water-soluble diaminostilbene-based fluorescent whitening agent,
For example, use of a sensitizing dye having a high hydrophilicity
No. 9936, but this is not yet sufficient.

Furthermore, high silver chloride print materials are inferior to other color image forming systems (eg, electrostatic transfer system, thermal transfer system, ink jet system) in terms of color gamut in bright areas. Color gamut is an important characteristic of color printing and image forming systems. The color gamut is a measure of the color range that can be formed using a predetermined combination of colorants. It is desirable that the color gamut be as large as possible. The color gamut of an image forming system is mainly controlled by the absorption characteristics of a colorant set used for image formation. Image forming systems typically use three or more colorants, typically including, for example, cyan, magenta, and yellow in conventional subtractive color image forming methods. It is also common in such forming systems to include an achromatic color such as black.

[0008] The ability to form an image containing a particular color
It is limited by the color gamut of the formation system and the material used for image formation. Therefore, the color range that can be used for image reproduction is limited by the forming system and the color gamut that the material can form. The color gamut is often considered to be maximized by using so-called "block dyes".

Further, by adding a dye or a pigment which is not decolored by the processing to color, or by adding a fluorescent whitening agent to the processed light-sensitive material, the white background can be adjusted to a preferable range of the present invention.

The pigment preferably used for coloring the hydrophilic colloid layer of the photographic constituent layer in the present invention will be described. The silver halide photographic light-sensitive material of the present invention is preferably a material in which at least one pigment is dispersed in at least one of a photosensitive silver halide emulsion layer and a non-light-sensitive layer coated on a reflective support. . In the present invention, the layer containing a pigment may be a photosensitive layer containing a silver halide emulsion,
Alternatively, any of an intermediate layer located between the silver halide emulsion layers, an ultraviolet absorbing layer located above the silver halide emulsion layer, and a non-photosensitive layer such as an undercoat layer of gelatin may be used.

It is often preferable to introduce a pigment into the non-photosensitive layer.

Usually, in order to overcome the yellow stain, a blue tint is applied. As this coloring, we usually antagonize yellow stain and make it neutral color,
The pigment is added in an amount sufficient to make it white to the human eye. Further, by using two or more types of pigments and changing the usage ratio of those pigments, it is possible to perform yellow stain correction in a wide range. In general, a combination of a blue pigment that changes the hue in the cyan direction and a red or violet pigment that changes the hue in the magenta direction is used. This allows a wide range of color adjustments.

Here, the silver halide color photographic light-sensitive material of the present invention will be described.

The silver halide emulsion layer functions as a cyan coloring layer. The silver halide emulsions contained in the yellow, magenta and cyan coloring layers, respectively, are sensitive to light in different wavelength ranges (for example, blue, green and red). It is preferable to have

The light-sensitive material of the present invention may have, if desired, a hydrophilic colloid layer, an antihalation layer, an intermediate layer and a coloring layer, which will be described later, in addition to the yellow, magenta and cyan coloring layers. Good.

The silver halide light-sensitive material preferably used in the present invention is described in detail below. The silver halide grains in the silver halide emulsion used in the present invention are preferably cubic or tetradecahedral crystal grains having substantially {100} faces (these grains have rounded apexes and higher order faces). Octahedral crystal grains, or tabular grains having an aspect ratio of 2 or more in which at least 50% of the total projected area is composed of {100} planes or {111} planes.
The aspect ratio is a value obtained by dividing the diameter of a circle corresponding to the projected area by the thickness of a particle. In the present invention, cubic or tabular grains having a {100} plane as a principal plane or tabular grains having a {111} plane as a principal plane are preferably applied.

Among such silver halide emulsions, 0.01 to 0.50 mol%, more preferably 0.05 to 0.5 mol%, per mol of total silver is added to the shell portion of silver halide grains.
Those having a silver iodochloride phase of from .about.0.40 mol% are also preferred because they provide high sensitivity and are excellent in high illuminance exposure suitability. Alternatively, those having a silver bromide localized phase of 0.2 to 5 mol%, more preferably 0.5 to 3 mol%, based on the total silver mole on the surface of silver halide grains can provide high sensitivity, and It is particularly preferable because photographic performance can be stabilized.

The emulsion of the present invention preferably contains silver iodide.

Further, fine silver iodide grains can be used as another iodide ion source.

The addition of the iodide salt solution may be carried out intensively during the grain formation, or may be carried out over a certain period of time. The position at which iodide ions are introduced into a high chloride emulsion is limited in order to obtain an emulsion having high sensitivity and low fogging.

Also, the addition of the iodide salt solution is preferably terminated within 98% of the particle volume, most preferably within 96% of the particle volume.

It is preferred to add. Further, the coating pH of the photosensitive material is preferably from 4.0 to 7.0, and more preferably from 4.0 to 6.5.

In the present invention, a surfactant can be added to the light-sensitive material from the viewpoints of improving the coating stability of the light-sensitive material, preventing generation of static electricity, and adjusting the charge amount. Examples of the surfactant include an anionic surfactant, a cationic surfactant, a betaine surfactant, and a nonionic surfactant, and examples thereof include those described in JP-A-5-333492.

The photosensitive material of the present invention can form an image by an exposure step of irradiating light in accordance with image information and a development step of developing the illuminated photosensitive material. The light-sensitive material of the present invention can be used for a cathode ray (CR) besides being used in a printing system using a normal negative printer.
It is also suitable for a scanning exposure method using T). A cathode ray tube exposure apparatus is simpler, more compact, and lower in cost than an apparatus using a laser. Further, adjustment of the optical axis and color is also easy. For the cathode ray tube used for image exposure, various luminous bodies that emit light in a spectral region are used as necessary. For example, any one of a red light emitter, a green light emitter, and a blue light emitter, or a mixture of two or more thereof is used. The spectral region is not limited to the above red, green, and blue, and a phosphor that emits light in a yellow, orange, purple, or infrared region is also used. In particular, a cathode ray tube which emits white light by mixing these light emitters is often used.

When the photosensitive material has a plurality of photosensitive layers having different spectral sensitivity distributions and the cathode tube also has a phosphor which emits light in a plurality of spectral regions, a plurality of colors are exposed at a time, that is, a cathode ray. A plurality of color image signals may be input to the tube to emit light from the tube surface. A method of sequentially inputting image signals for each color, sequentially emitting light of each color, and exposing through a film that cuts a color other than that color (plane sequential exposure)
In general, plane-sequential exposure is preferable for improving image quality because a cathode ray tube with high resolution can be used.

The photosensitive material of the present invention is a gas laser, a light emitting diode, a semiconductor laser, a semiconductor laser, or a second harmonic emission light source (SHG) in which a solid-state laser using a semiconductor laser as an excitation light source is combined with a nonlinear optical crystal.
A digital scanning exposure method using monochromatic high-density light is preferably used. In order to make the system compact and inexpensive, it is preferable to use a semiconductor laser, a semiconductor laser or a second harmonic generation light source (SHG) in which a solid-state laser is combined with a nonlinear optical crystal. Particularly, in order to design an apparatus that is compact, inexpensive, and has a long life and high stability, it is preferable to use a semiconductor laser, and it is preferable to use a semiconductor laser as at least one of the exposure light sources.

When such a scanning exposure light source is used,
The spectral sensitivity maximum wavelength of the light-sensitive material of the present invention can be arbitrarily set according to the wavelength of the scanning exposure light source to be used.
In a solid-state laser using a semiconductor laser as an excitation light source or an SHG light source obtained by combining a semiconductor laser and a nonlinear optical crystal, the laser oscillation wavelength can be halved, so that blue light and green light can be obtained. Therefore, the spectral sensitivity maximum of the photosensitive material can be provided in the usual three wavelength ranges of blue, green and red. If the exposure time in such scanning exposure is defined as the exposure time for the pixel size when the pixel density is 400 dpi, the preferred exposure time is 10 ^-4 seconds or less, more preferably 10 ^-6 seconds or less.

Exposure may be performed a plurality of times on the same photosensitive layer, and in that case, it is preferable to perform at least three times. Particularly preferably, the exposure time is 10 ^-4 to 10 ^-8 seconds, and when the exposure time is 10 ^-5 to 10 ^-8 seconds, it is preferable to perform at least 8 exposures. As a light source,
Gas laser, solid-state laser (LD), LED (inorganic,
Organic), Xe light source with a narrowed spot, etc.
Particularly, solid lasers and LEDs are preferable. The light source needs to be spectrally separated to the color-sensitive wavelength of each dye-forming layer. For this purpose, an appropriate color filter (containing a dye or vapor deposition) or an LD or LED oscillation wavelength is selected and used. You may. Further, both may be used in combination. The spot diameter of the light source is not particularly limited, but is preferably 5 to 250 μm, more preferably 10 to 100 μm, as a half width of the light intensity. The shape of the spot may be any of a circle, an ellipse, and a rectangle. The light quantity distribution of one spot may be a Gaussian distribution, or may be a trapezoid with relatively constant intensity. In particular, the number of light sources may be one or an array in which a plurality of light sources are arranged.

In the present invention, exposure is generally performed by scanning exposure, and the light source may be scanned or the photosensitive material may be scanned. Alternatively, both of them may be scanned. One exposure time is defined by the following equation. Exposure time = spot diameter / moving speed of light source (or moving speed of photosensitive material) Here, the spot diameter is a diameter of a spot in a direction in which a light source used for scanning exposure moves at the time of exposure (half width, unit:
μm). The moving speed of the light source is the speed at which the light source used for scanning exposure moves per unit time (unit:
μm / sec). In general, the spot diameter need not be the same as the pixel diameter, but may be larger or smaller. The number of exposures referred to in the present invention is the number of times that one point (pixel) on the photosensitive material is irradiated with light that is perceived by the same color-sensitive layer,
In the case of a plurality of irradiations, the number of exposures is 1/5 or more of the maximum exposure intensity. Therefore, 1 /
Exposure less than 5, stray light, and overlap between spots are not included in the number of times.

When exposing the light-sensitive material of the present invention to a printer, it is preferable to use a band stop filter described in US Pat. No. 4,880,726. As a result, light color mixing is removed, and color reproducibility is significantly improved. In the present invention, as described in European Patent Nos. EP0789270A1 and EP0789480A1, before applying image information, a yellow microdot pattern may be pre-exposed in advance to control copying.

Typically, a minilab “PP350” manufactured by Fuji Photo Film Co., Ltd. and CP48S Chemical as a processing agent are used for color development processing for defining the hue and white background in the present invention. There is a type in which image-wise exposure is performed from a film and processing is performed using a processing solution that has been subjected to continuous processing until the volume of a color developing replenisher becomes twice the capacity of the color developing tank.

The chemicals of the treating agent may be CP45X and CP47L manufactured by Fuji Photo Film Co., Ltd., RA-100 and RA-4 manufactured by Eastman Kodak Co., Ltd.

It is less than 0 seconds and more than 6 seconds. The washing or stabilizing time is preferably 150 seconds or less, more preferably 130 seconds or less and 6 seconds or more.

The term "color developing time" means the time from when the photosensitive material enters the color developing solution to when it enters the bleach-fixing solution in the next processing step. For example, when processing is performed by an automatic developing machine or the like, the time during which the photosensitive material is immersed in the color developing solution (so-called submerged time) and the time when the photosensitive material leaves the color developing solution and bleach in the next processing step The sum of the time during which the paper is conveyed through the air toward the fixing bath (so-called air time) is referred to as the color development time. Similarly, the bleach-fixing time refers to the time from when the photosensitive material enters the bleach-fixing solution to when it enters the next washing or stabilizing bath.

In addition to a wet method such as a method of developing with an activator solution such as a method described above, a thermal developing method without using a processing solution can be used. In particular, the activator method is a preferable method from the viewpoint of environmental protection because the developing agent is not contained in the processing solution, so that the processing solution can be easily managed and handled, and the load at the time of processing the waste solution is small. In the activator method, examples of the developing agent or its precursor incorporated in the photosensitive material include, for example, JP-A-8-2343.

In the activator method, after processing with the activator solution, usually desilvering processing, but in the image amplification processing method using a low silver content photosensitive material,
The desilvering process can be omitted, and a simple method such as washing or stabilizing can be performed. Further, in a method in which image information is read from a photosensitive material by a scanner or the like, a processing mode that does not require desilvering processing can be adopted even when a photosensitive material having a high silver content such as a photosensitive material for photographing is used.

As the activator solution, desilvering solution (bleaching / fixing solution), water washing and stabilizing solution used in the present invention, known materials and processing methods can be used. Preferably, Research Disclosure Item 3654

For each sample, a U-3410 type spectrophotometer manufactured by Hitachi, Ltd. was used under the conditions of 25 ° C. and 60% RH, and the reflection density at the point where the integrating sphere aperture ratio was 2%, the slit width was 5 nm, and the specular light was excluded was used. It was measured.

The reflection density of a white background (unexposed area) is λ = 450
nm, 550 nm, and 650 nm.
(450), A (550), and A (650). A (550) / A (450), A (650) / A from measured values
(450) was calculated.

The reflection density of the cyan-colored portion is set to 25 as in the case of a white background.
Using a U-3410 type spectrophotometer manufactured by Hitachi, Ltd. under the conditions of 60 ° C. and 60% RH, the measurement was performed with an integrating sphere aperture ratio of 2%, a slit width of 5 nm, and excluding specular light. At that time, scanning was performed from 400 nm to 700 nm, and a sample having a density of 1.0 at the wavelength giving the maximum density was calculated from the wedge-exposed sample to prepare. The minimum density in scanning from 400 nm to 700 nm is C (min), the reflection density at a wavelength of 425 nm is C (425), and the reflection density at a wavelength of 530 nm is C (53).
0). From the value obtained by the above measurement, (C (4
25) -C (min)) / (1-C (min)) and (C
(530) -C (min)) / (1-C (min)) was calculated.

As an index of the color reproduction range, the density of each of the cyan, magenta, and yellow coloring portions of each sample subjected to color development processing in processing step A using the sample exposed through the wedge was measured using a C -2000 color analyzer and xenon conventional light source to obtain a density of 0.
The measurement was performed at one interval, and the color reproducible L ^* a ^* b ^* chromaticity space volume V was calculated using D65 as a white point. As the L ^* a ^* b ^* chromaticity space volume V increases, the region in which color can be reproduced increases, and the region in which faithful color reproduction can be performed increases.

After the coating was stored for 10 days at 25 ° C. and 55% RH, the unexposed sample which had been subjected to color development processing A of 30 cm × 30 cm was subjected to a sensory evaluation of a white background according to the following criteria.
The average was calculated for 0 subjects. 5 points: Excellent in whiteness. 4 points: Excellent in whiteness. 3 points: Normally white. 2 points: Slightly colored. 1 point: Tint. 0 point: not white.

For each sample, as a sensory evaluation of color reproducibility, a negative film on which Macbeth ColorChecker chart was copied was obtained using SUPE manufactured by Fuji Photo Film Co., Ltd.
Prepared using RIA400, Yellow-Gree
Regarding the color reproducibility of n and Green, an average value was calculated for 50 persons based on the following criteria. 5 points: The color is faithfully reproduced and extremely vivid. 4 points: Vivid, almost faithfully reproduced. 3 points: Somewhat cloudy but tolerable, lacking in vividness. 2 points: It is cloudy. Not vivid. 1 point: quite cloudy, not very vivid. 0 point: Color is different.

To evaluate the stability of the color image, each sample was stored at 25 ° C. and 55% RH for 10 days and then passed through a three-color separation wedge for 0.1 second and 200 lux with a FWK type sensitometer manufactured by Fuji Photo Film Co., Ltd. Exposure for 1 second (lx · sec) was given, and color development was performed in processing step A described below. These samples were preserved by heating at 80 ° C. and 20% for 10 days, and the concentration change before and after the preservation at a point of concentration 1.0 before the preservation was measured.
The residual concentration was calculated as a percentage when the concentration before storage under heat was set to 100, and the resulting value was regarded as heat fastness. The concentration measurement was performed by Gretag
The measurement was performed using SpectroEye manufactured by Macbeth. Table 2 shows the evaluation results.

[Table 2]

In Table 2, a comparison between Samples 001 and 002 shows that (C (425) -C (min)) / (1-C
(Min)) and (C (530) -C (min)) / (1
−C (min)) can be seen to increase the color reproduction volume V by 4% when the value falls within the default value of the present invention. In the sample 102 in which both are combined, the color reproduction volume V is increased by 13%, and an unexpected effect is recognized. A similar effect is also observed for Macbeth reproducibility, which is a sensory evaluation. It can be seen that the same effect can be obtained not only in the calculation from the measured values but also in the sensory evaluation by improving the Macbeth reproducibility. As described above, it can be seen that the color reproducibility of each of the samples of the present invention is greatly increased.
