Definitions
- the present invention relates to a silver halide photographic light-sensitive material.
- the present invention relates to a silver halide color photographic light-sensitive material that is excellent in color reproduction and image storability (preservability).
- a color image is formed by dyes of three primary colors of yellow, magenta, and cyan.
- acylacetoanilide-series compounds are used as a yellow coupler.
- the hue of the yellow dyes obtained from these yellow couplers becomes reddish, due to an inferior sharpness of a peak of the absorption curve at the longer wavelength side (that is, on the absorption curve, the peak in interest has subsidiary absorption at its foot portion at the longer wavelength side), which renders it difficult to obtain a yellow hue with high purity.
- the molecular extinction coefficient of the yellow dyes is low, it is necessary, to attain a desired color density, to use larger amounts of both the coupler and the silver halide.
- the use of such larger amounts of these components raises the problem that the resulting increase in thickness of a light-sensitive material sometimes lowers the sharpness of the obtained color image.
- the above-mentioned dyes are sometimes easily decomposed under conditions of high temperature and high humidity, or under long-time light irradiation, and thus they have insufficient image storability after development processing. Therefore, it has been desired to improve on these problems.
- JP-A-52-82423 and JP-A-2-28645 propose acetate ester-series and acetoanilide-series couplers to which 1,2,4-benzothiadiazine-1,1-dioxide is bonded.
- these couplers are low in color-forming property, they are inferior in sharpness of a peak of the absorption curve owing to the foot portion on the longer wavelength side, and they are low in image fastness. Therefore, improvement of these properties has been desired.
- An object of the present invention is to provide a silver halide photographic light-sensitive material that overcomes the above-mentioned problems. Another object of the present invention is to provide a silver halide photographic light-sensitive material that has excellent color-forming property and gives dyes of excellent hue and high-grade storability, whereby neither a white background portion nor a dye image portion become discolored or fade for a long time. Still another object of the present invention is to provide a silver halide photographic light-sensitive material that provides not only excellent color-forming property and hue of dye but also little fog and color mixing, a dye image that will not change for a long time, and little fluctuation of color-forming property even after long-term storage after coating (good virgin stock storability). Further another object of the present invention is to provide a silver halide color photographic light-sensitive material that provides not only excellent color-forming property and hue of dye but also excellent in development processing stability, and dye image formed will not discolor for a long time.
- the coupler is incorporated in an oil-in-water dispersion process using a high boiling point organic solvent.
- a high boiling point organic solvent triphenyl phosphate, tricresyl phosphate, 2-ethylhexyldiphenyl phosphate, tricyclohexyl phosphate, tri-2-ethylhexylphosphate, tridodecyl phosphate and tributoxyethyl phosphate are mentioned.
- samples 402 to 413 of example 3 samples 502 to 516 of example 6 and the similar example 7 make use of one blue sensitive photographic emulsion layer comprising a mixture of yellow dye-forming couplers and phenolic type additives.

Abstract
Description
- The present invention relates to a silver halide photographic light-sensitive material. Particularly, the present invention relates to a silver halide color photographic light-sensitive material that is excellent in color reproduction and image storability (preservability).
- In a silver halide photographic light-sensitive material (hereinafter, also referred to simply as "a light-sensitive material") for subtractive color photography, a color image is formed by dyes of three primary colors of yellow, magenta, and cyan. In the color photography that uses current p-phenylenediamine-series color-developing agents, acylacetoanilide-series compounds are used as a yellow coupler. However, the hue of the yellow dyes obtained from these yellow couplers becomes reddish, due to an inferior sharpness of a peak of the absorption curve at the longer wavelength side (that is, on the absorption curve, the peak in interest has subsidiary absorption at its foot portion at the longer wavelength side), which renders it difficult to obtain a yellow hue with high purity. Further, because the molecular extinction coefficient of the yellow dyes is low, it is necessary, to attain a desired color density, to use larger amounts of both the coupler and the silver halide. The use of such larger amounts of these components raises the problem that the resulting increase in thickness of a light-sensitive material sometimes lowers the sharpness of the obtained color image. Further, the above-mentioned dyes are sometimes easily decomposed under conditions of high temperature and high humidity, or under long-time light irradiation, and thus they have insufficient image storability after development processing. Therefore, it has been desired to improve on these problems.
- In order to solve these problems, improvement of acyl groups and anilido groups were proposed on the couplers. Recently, as improved couplers of the conventional acylacetoanilide-series couplers, there were proposed, for example, 1-alkylcyclopropanecarbonyl acetoanilide-series compounds, described in
JP-A-4-218042 JP-A-5-11416 European Patent Publication Nos. 953870A1 953871A1 953872A1 953873A1 953874A1 953875A1 U.S. Patent No. 3,841,880 ,JP-A-52-82423 JP-A-2-28645 - An object of the present invention is to provide a silver halide photographic light-sensitive material that overcomes the above-mentioned problems. Another object of the present invention is to provide a silver halide photographic light-sensitive material that has excellent color-forming property and gives dyes of excellent hue and high-grade storability, whereby neither a white background portion nor a dye image portion become discolored or fade for a long time. Still another object of the present invention is to provide a silver halide photographic light-sensitive material that provides not only excellent color-forming property and hue of dye but also little fog and color mixing, a dye image that will not change for a long time, and little fluctuation of color-forming property even after long-term storage after coating (good virgin stock storability). Further another object of the present invention is to provide a silver halide color photographic light-sensitive material that provides not only excellent color-forming property and hue of dye but also excellent in development processing stability, and dye image formed will not discolor for a long time.

- A more preferable reflective support for use in the present invention is a support having a paper substrate provided with a polyolefin layer having fine holes, on the side to which silver halide emulsion layers are to be provided. The polyolefin layer may be composed of multilayers. In this case, it is more preferable for the support to be composed of a fine hole-free polyolefin (e.g., polypropylene, polyethylene) layer adjacent to a gelatin layer on the same side as the silver halide emulsion layers, and a fine hole-containing polyolefin (e.g., polypropylene, polyethylene) layer closer to the paper substrate.

Further, it is also preferable for enhancing rigidity (mechanical strength) of the reflective support, to provide a polyolefin layer on the side of the foregoing paper substrate opposite to the side of the photographic constituting layers, i.e., on the back surface of the paper substrate. In this case, it is preferable that the polyolefin layer on the back surface be polyethylene or polypropylene, the surface of which is matted, with the polypropylene being more preferable. The thickness of the polyolefin layer on the back surface is preferably in the range of 5 to 50 µm, and more preferably in the range of 10 to 30 µm, and further the density thereof is preferably in the range of 0.7 to 1.1 g/ml.

Alternatively, a silver halide emulsion in which the proportion of tabular grains having an aspect ratio of 2 or more and composed of {100} or {111} planes accounts for 50% or more in terms of the total projected area, can also be preferably used. The term "aspect ratio" refers to the value obtained by dividing the diameter of the circle having an area equivalent to the projected area of an individual grain by the thickness of the grain. In the present invention, cubic grains, or tabular grains having {100} planes as major faces, or tabular grains having {111} planes as major faces are preferably used.
- As a silver halide emulsion which can be used in the present invention, for example, silver chloride, silver bromide, silver iodobromide, or silver chloro(iodo)bromide emulsions may be used. It is preferable for a rapid processing to use a silver chloride or silver chlorobromide emulsion having a silver chloride content of 95 mol% or greater, and more preferably a silver halide emulsion having a silver chloride content of 98 mol% or greater. Among these silver halide emulsions, those emulsions composed of silver chloride grains each having a silver bromide-localized phase on the surface of a grain are particularly preferable, since both high sensitivity and stabilization of photographic performances are attained.
- The silver bromide-localized phase (silver bromide-rich phase) is preferably formed by epitaxially growing a localized phase having a silver bromide content of at least 10 mole% in terms of the total silver bromide content in the silver bromide-rich phase. The silver bromide content in the silver bromide-rich phase is preferably in the range of 10 to 60 mole%, and most preferably in the range of 20 to 50 mole%. The silver bromide-rich phase is composed of silver in an amount of preferably 0.1 to 5 mole%, more preferably 0.3 to 4 mole%, based on the amount of entire silver constituting the silver halide grains for use in the present invention. A Group VIII metal complex ion, such as IrCl6 3-, can be preferably incorporated in the silver bromide-rich phase.

Examples of the compounds that can be used include salts or complex salts of group VIII metals in the periodic table, such as iron, iridium, ruthenium, osmium, rhenium, rhodium, cadmium, zinc, lead, copper, and thallium. These compounds may be used in combination. In the present invention, compounds composed of a metal, such as iron, ruthenium, osmium or rhenium, and at least four (4) cyano ligands are especially preferable, from the view points that a high intensity illumination sensitivity is further enhanced, whereas a latent image sensitization is refrained. Further, iridium compounds also provide an outstanding effect on giving suitability to the high illumination intensity exposure. The addition amount of these compounds varies in a wide range according to the purposes for uses, but preferably it is in the range of 10-9 to 10-2 mole per mole of silver halide.
- The silver halide emulsion for use in the present invention is generally subjected to chemical sensitization. Chemical sensitization can be performed by utilizing a sulfur sensitization represented by the addition of an unstable sulfur compound, a noble metal sensitization represented by gold sensitization, a reduction sensitization, and the like methods, each singly or in combination thereof. Compounds that are preferably used in chemical sensitization include those described in
JP-A-62-215272 - The silver halide photographic light-sensitive material of the present invention can be used for various materials such as color negative films, color positive films, color reversal films, color reversal papers, color papers, motion-picture color negatives, motion-picture color positives, display photosensitive materials, and color proof (especially, digital color proof) photosensitive materials.

- The yellow coupler-containing silver halide emulsion layer may be disposed at any position on a support. Further, in the case where the silver halide tabular grains are contained in the yellow coupler-containing layer, it is preferable that the yellow coupler-containing layer is positioned more apart from the support than at least one of the magenta coupler-containing silver halide emulsion layer and the cyan coupler-containing silver halide emulsion layer. Further, it is preferable that the yellow coupler-containing silver halide emulsion layer is positioned most apart from the support of other silver halide emulsion layers, from the viewpoints of color-development acceleration, desilvering acceleration, and lowering of a residual color due to a sensitizing dye. Further, it is preferable that the cyan coupler-containing silver halide emulsion layer is positioned in the middle of other silver halide emulsion layers, from the viewpoint of reduction in a blix fading. On the other hand, it is preferable that the cyan coupler-containing silver halide emulsion layer is the lowest layer, from the viewpoint of reduction in a light fading. Further, each of a yellow-color-forming layer, a magenta-color-forming layer and a cyan-color-forming layer may be composed of two or three layers. It is also preferable that a color-forming layer is formed by disposing a silver halide emulsion-free layer containing a coupler, in adjacent to a silver halide emulsion layer, as described in, for example,

WO 98/33760 JP-A-10-221825 - As fungiproofing/mildewproofing agents that can be used in the present invention, those described in
JP-A-63-271247 - The light-sensitive material of the present invention can preferably be used, in addition to the printing system using a general negative printer, in a scanning exposure system using a cathode ray tube (CRT).
- The cathode ray tube exposure apparatus is simpler and more compact, and therefore less expensive than a laser-emitting apparatus. Further, optical axis and color (hue) can easily be adjusted.
- In a cathode ray tube that is used for image-wise exposure, various light-emitting substances which emit a light in the spectral region, are used as occasion demands. For example, any one of red-light-emitting substances, green-light-emitting substances, blue-light-emitting substances, or a mixture of two or more of these light-emitting substances may be used. The spectral regions are not limited to the above red, green and blue, and fluorescent substances which can emit a light in a region of yellow, orange, purple or infrared can be used. Particularly, a cathode ray tube that emits a white light by means of a mixture of these light-emitting substances is often used.
- When the light-sensitive material has a plurality of light-sensitive layers having different spectral sensitivity distributions and a cathode ray tube has fluorescent substances emitting lights in a plurality of spectral regions, a plurality of colors may be exposed at the same time, i.e., image signals of a plurality of colors may be input to the cathode ray tube and emitted from the tube surface. Alternatively, an exposure method comprising inputting an image signal of each color in order, and emitting light of each color in order through a filter cutting other colors than that color (i.e., area sequential exposure) may be adopted. In general, such an area sequential exposure is preferred for obtaining a high quality image because a cathode ray tube having high resolving power can be used.
- The light-sensitive material of the present invention can preferably be used in the digital scanning exposure system using monochromatic high density light, such as a gas laser, a light-emitting diode, a semiconductor laser, a second harmonic generation light source (SHG) comprising a combination of nonlinear optical crystal with a semiconductor or a solid state laser using a semiconductor laser as an excitation light source. It is preferred to use a semiconductor laser, or a second harmonic generation light source (SHG) comprising a combination of nonlinear optical crystal with a solid state laser or a semiconductor laser, to make a system more compact and inexpensive. In particular, to design a compact and inexpensive apparatus having a longer duration of life and high stability, use of a semiconductor laser is preferable; and it is preferred that at least one of exposure light sources should be a semiconductor laser.
- When such a scanning exposure light source is used, the maximum spectral sensitivity wavelength of the light-sensitive material of the present invention can be arbitrarily set up in accordance with the wavelength of a scanning exposure light source to be used. Since oscillation wavelength of a laser can be made half,using a SHG light source obtainable by a combination of a nonlinear optical crystal with a semiconductor laser or a solid state laser using a semiconductor as an excitation light source, blue light and green light can be obtained. Accordingly, it is possible to have the spectral sensitivity maximum of a photographic material in normal three wavelength regions of blue, green and red.
- The exposure time in such a scanning exposure is defined as the time necessary to expose the size of the picture element (pixel) with the density of the picture element being 400 dpi, and preferred exposure time is 10-4 sec or less and more preferably 10-6 sec or less.
- The scanning exposure system that can preferably be used in the present invention is described in detail in the patent publications shown in the above table.
- With respect to the processing of the light-sensitive material of the present invention, processing materials (including details for color developing agents) and processing methods, as disclosed in
JP-A-2-207250 JP-A-4-97355 - The present invention is preferably applied to a light-sensitive material having rapid processing suitability.
- The term "color-developing time" as used herein refers to a period of time required from the beginning of dipping a light-sensitive material into a color-developing solution until the light-sensitive material is dipped into a blix solution in the subsequent processing step. In the case where a processing is carried out using, for example, an autoprocessor, the color-developing time is the sum total of a time in which a light-sensitive material has been dipped in a color-developing solution (so-called "time in the solution") and a time in which the light-sensitive material has been conveyed in air toward a bleach-fixing bath in the step subsequent to color development (so-called "time in the air"). Likewise, the term "blix time" as used herein refers to a period of time required from the beginning of dipping a light-sensitive material into a blix solution until the light-sensitive material is dipped into a washing bath or a stabilizing bath in the subsequent processing step. Further, the term "washing or stabilizing time" as used herein refers to a period of time required from the beginning of dipping a light-sensitive material into a washing solution or a stabilizing solution until the end of the dipping toward a drying step (so-called "time in the solution").
- In the present invention, the color-developing time is preferably 60 sec or less, more preferably from 50 sec to 6 sec, further preferably from 30 sec to 6 sec. Likewise, the blix time is preferably 60 sec or less, more preferably from 50 sec to 6 sec, further preferably from 30 sec to 6 sec. Further, the washing or stabilizing time is preferably 150 sec or less, more preferably from 130 sec to 6 sec.
- When the silver halide color photosensitive material of the present invention is a silver halide color photosensitive material having a reflective-type support (e.g. color paper), the following exposure and development systems can be mentioned: Automatic printing and development system described in
JP-A-10-333253 JP-A-2000-10206 JP-A-11-215312 JP-A-11-88619 JP-A-10-202950 JP-A-10-210206 JP-A-2000-310822 - In specific, those can be mentioned are, for example, Minilabo "PP350" (trade name) manufactured by Fuji Photo Film Co., Ltd., and, as a processing agent, CP48S Chemical, CP45X, or CP47L, manufactured by Fuji Photo Film Co., Ltd., or RA-100, RA-4, manufactured by Eastman Kodak Co., (each trade name).
- Examples of a development method applicable to the light-sensitive material of the present invention after exposure, include a conventional wet system, such as a development method using a developing solution containing an alkali agent and a developing agent, and a development method wherein a developing agent is incorporated in the photographic material and an activator solution, e.g., a developing agent-free alkaline solution, is employed for the development, as well as a heat development system using no processing solution. In particular, the activator method is preferred over the other methods, because the processing solution contains no developing agent, thereby it enables easy management and handling of the processing solution, and reduction in waste disposal load to make for environmental preservation.
- The preferable developing agents or their precursors to be incorporated in the photographic materials in the case of adopting the activator method include the hydrazine compounds described in, for example,
JP-A-8-234388 JP-A-9-152686 JP-A-9-152693 JP-A-9-211814 JP-A-9-160193 - Further, the processing method in which the light-sensitive material reduced in the amount of silver to be applied undergoes the image amplification processing using hydrogen peroxide (intensification processing), can be employed preferably. In particular, it is preferable to apply this processing method to the activator method. Specifically, the image-forming methods utilizing an activator solution containing hydrogen peroxide, as disclosed in
JP-A-8-297354 JP-A-9-152695 - The processing with an activator solution is generally followed by a desilvering step in the activator method, but the desilvering step can be omitted in the case of applying the image amplification processing method to photographic materials of a low silver amount. In such a case, washing or stabilization processing can follow the processing with an activator solution to result in simplification of the processing process. On the other hand, when the system of reading the image information from photographic materials by means of a scanner or the like is employed, the processing form requiring no desilvering step can be applied, even if the photographic materials are those of a high silver amount, such as photographic materials for shooting.
- The activator solution, desilvering solution (bleach-fixing solution), washing solution and stabilizing solution for use in the present invention can contain known ingredients and can be used in conventional manners. Preferably, those described in Research Disclosure, Item 36544, pp. 536-541 (September 1994), and
JP-A-8-234388 - The light-sensitive material of the present invention can be preferably used as a light-sensitive material for the advanced photo-system, which has a magnetic recording layer. The light-sensitive material of the present invention can be preferably used in a system wherein a small amount of water is used to perform heat-development, or in a complete dry system wherein no water is used to perform heat-development. Detailed descriptions on these systems are found, for example, in
JP-A-6-35118 JP-A-6-17528 JP-A-56-146133 JP-A-60-119557 JP-A-1-161236 - In the present invention, the wording "a silver halide photographic light-sensitive material" means to include not only a light-sensitive material for forming a color image but also a light-sensitive material for forming a monotone image, an example of which is a black and white image.
- In case where the present invention is applied to a color paper, the light-sensitive material and the like described in
JP-A-11-7109 JP-A-11-7109 JP-A-11-7109 - In case where the present invention is applied to a color negative film, the descriptions at paragraph Nos. 0115 to 0217 of the specification of

- (A) A silver halide color photographic light-sensitive material, having at least one blue-sensitive emulsion layer containing a yellow coupler, at least one green-sensitive emulsion layer containing a magenta coupler, and at least one red-sensitive emulsion layer containing a cyan coupler, on a support;
- According to the present invention, a silver halide photographic light-sensitive material that gives dyes excellent in hue and shows excellent color-forming property, and high-grade storability, whereby neither a white background portion nor a dye image portion become discolored or fade for a long time, can be provided at low cost. The silver halide photographic light-sensitive material of the present invention provides an image with little fog and color mixing, and it provides little reduction of the developed color density, even after long-term storage after coating as a raw stock; and it further provides excellent development processing stability.

Thus, a high-sensitive emulsion A-1 was prepared.
- Similarly, cubic grains having an average side length of 0.55 µm (variation coefficient of the side length, 9%) were prepared. Spectral sensitization and chemical sensitization were carried out in the same manner as the above, except for correcting the sensitization amounts so as to adjust the specific surface area (according to side length ratio 0.7/0.55=1.27 times). Thus, a low-sensitive emulsion A-2 was prepared.
- A high-sensitive green-sensitive emulsion C-1 and a low-sensitive green-sensitive emulsion C-2 were prepared in the same manner as Emulsion A-1 and Emulsion A-2 respectively, except that the temperature at the grain formation was lowered and kinds of the sensitizing dyes were changed as shown below.
