Description

  The present invention relates to a novel silver halide color light-sensitive material, and more particularly, to a silver halide color light-sensitive material having excellent pressure resistance and improved dark fading resistance and bleeding resistance during image storage.

  Silver halide color light-sensitive materials (hereinafter also simply referred to as light-sensitive materials) are actively used today because of their high sensitivity, excellent color reproducibility, and suitability for continuous processing. For silver halide color photographic materials for general photography that have been widely used in the past, for example, in a method of photographing with a color negative film and printing a color image obtained through a development process using an optical system, the printing conditions are set in advance. With this setting, the printing conditions are easily determined and adjusted based on the result of measuring the density of the color negative film, and the color print photosensitive material (color photographic paper) is a full-color excellent color image with a single exposure. This is a system that can obtain print images continuously and has extremely high productivity. In addition, this color photographic paper has recently been used in a digital image forming method for forming a color image by modulating the amount of light from an exposure light source such as a laser or LED by image data taken with a digital camera or the like. . Also in digital image exposure, normally, modulated three-color lights of B, G, and R are mixed, and a color image is formed by one scan, which shows high productivity similar to the conventional one.

  In addition, recording materials using silver halide color light-sensitive materials are known to have low noise, particularly at low densities, and have characteristics that enable very smooth gradation reproduction. When the apparatus has a sufficient gradation reproduction capacity, it has a feature that it is excellent in highlight delineability. Because of these characteristics, silver halide color light-sensitive materials are widely used not only in the field of photography, but also in the field of printing, in the field of so-called color proofing for checking the state of finished prints in the middle of printing. It is becoming.

  In the field of proofing, a color image edited on a computer is output to a printing film, and the developed film is subjected to separation exposure while appropriately replacing the film, whereby yellow (Y), magenta (M), cyan (C ), And an image of the final printed matter is formed on color photographic paper, thereby determining the layout and color suitability of the final printed matter.

  Recently, a method of directly outputting an image edited on a computer to a printing plate has gradually become widespread, and in such a case, a color image can be obtained directly from the data on the computer without using a film. It was desired.

  For this purpose, various methods such as a sublimation type / melting heat transfer method, an electrophotographic method, and an ink jet method have been tried. However, a method capable of obtaining a high-quality image is expensive and inferior in productivity. In addition, there is a disadvantage that the image quality is inferior in a method that is low in cost and excellent in productivity.

  The system using silver halide color light-sensitive materials enables high-quality image formation, such as the ability to form accurate halftone images due to excellent sharpness, etc. On the other hand, continuous development processing is possible as described above. High productivity can be realized from the standpoints that images can be simultaneously written to a plurality of color image forming units.

  In recent years, digitization has progressed in the field of printing, and there is an increasing demand for obtaining an image directly from data in a computer. For the above-described reasons, for example, a halogen as disclosed in JP-A-2001-235816. Silver halide color light-sensitive materials are beginning to be used advantageously in this field.

  The most commonly used color image forming method as a silver halide color light-sensitive material is to react an oxidized aromatic primary amine color developing agent with a coupler using exposed silver halide as an oxidizing agent. To form indophenol, indoaniline, indamine, azomethine, phenoxazine, phenazine and similar dyes. In such an image forming method, a method of reproducing a color image by a subtractive color method is used. In general, a color image is formed by changing the generation amount of three colors of yellow, magenta, and cyan. Yes. Of these, acylacetanilide couplers are widely used as color developing couplers used for forming yellow dye images. Benzoylacetanilide type compounds with good color development are preferred for silver halide color photosensitive materials for photography, and pivaloyl acetanilide type compounds with excellent color tone are preferred for ornamental silver halide color photosensitive materials. ing.

  The basic properties required for these couplers are: excellent spectral absorption characteristics of the dye formed, high dye formation speed, high color density, and light, heat, It is desired to have various properties such as high fastness to moisture. In particular, in recent years when high sensitivity and high image quality are required for silver halide color light-sensitive materials, there is a strong demand for the development of couplers that have high color density and high light-fastness of the dyes formed. .

  Examples of yellow couplers with improved color reproducibility, high color developability and light fastness in response to the above-mentioned problems include, for example, the second position of the anilide moiety as described in JP-A-63-123047. And yellow couplers having an alkoxy group and an acylamino group at the 5-position. However, these couplers inherently have high pKa, and improvements are desired in terms of color development.

  Conventional yellow dye-forming couplers have low color reproducibility and low extinction coefficient of the dyes formed, so a large amount of couplers and silver halides are required to obtain the required color density, and as a result, silver halide There are problems such as an increase in the cost of the color light-sensitive material, an increase in film thickness, and a decrease in the sharpness of the resulting color image. As a coupler for solving this problem, an acetanilide type coupler in which pyrimidin-4-one in which an alkyl group having 1 to 6 carbon atoms is substituted with a nitrogen atom is bonded is disclosed (for example, see Patent Document 1). However, since the coupler proposed here is substantially characterized by a leaving group, it can be preferably used for a silver halide color light-sensitive material for general photography, but it can be used as an ornamental silver halide color light-sensitive material. Was not sufficient from the viewpoint of color developability.

  In addition, an acetanilide coupler to which a pyrimidin-4-one substituted with a substituted alkyl group is bonded (for example, see Patent Document 2), and an acetanilide to which a pyrimidin-4-one substituted with an aryl group or a heterocyclic group is bonded. An acetanilide type coupler (for example, see Patent Document 4) to which a pyrimidin-4-one introduced with a divalent linking group such as a hetero atom is bonded. In addition, acetanilide type couplers (see, for example, Patent Document 5) to which pyrimidin-4-one substituted with an alkyl group having 7 or more carbon atoms are bonded have been proposed, and color reproducibility and light resistance are further improved. Yes. Further, for the purpose of further improving the color reproducibility of a yellow image, an acetanilide type coupler to which [1,2,4] thiadiazine-1,1-dioxide is bonded has been proposed (for example, Patent Documents 6 and 7). reference.).

  Although it is a silver halide color light-sensitive material that is quite popular as described above, there are some very strict performance requirements.

For example, improvements in the handling performance of the photosensitive material itself, the stability of an image obtained after development processing, color reproduction, and the like continue to be highly demanded. The color reproducibility of the image can be improved to some extent by using the couplers described in the above-mentioned patent documents, but the performance at the time of handling the photosensitive material itself and the stability of the image are not yet achieved. It is not satisfactory. In particular, when handling the photosensitive material, an external pressure is applied to the surface of the photosensitive material in an undeveloped state, and yellow streaks are generated in the white background after the development process. When stored at high temperature and high humidity for a long period of time, the color image density decreases, so-called dark fading, and when the color image is stored at high temperature and high humidity, image blurring occurs. Thus, development of a silver halide color photographic material improved in these has been desired.

  As the exposure light source of the exposure apparatus used in the present invention, any known light source can be preferably used, but a laser or a light emitting diode (hereinafter referred to as LED) is more preferably used.

  As the laser, a semiconductor laser (hereinafter referred to as LD) is preferably used because it is compact and has a long light source life. LDs are used for applications such as DVDs, optical pickups for music CDs, barcode scanners for POS systems, optical communications, etc., and they are inexpensive and can provide relatively high output. have. Specific examples of the LD include aluminum, gallium, indium, arsenic (650 nm), indium, gallium, phosphorus (up to 700 nm), gallium, arsenic, phosphorus (610-900 nm), gallium, aluminum, arsenic (760-850 nm). And the like. Recently, a laser that oscillates blue light has been developed. However, at present, it is advantageous to use an LD as a light source having a wavelength longer than 610 nm.

  As a laser light source having an SHG element, light emitted from an LD or YAG laser is converted to a half-wavelength light by an SHG element and emitted, and since visible light is obtained, there is no green light source. ~ Used as a light source in the blue region. An example of this type of light source is a YAG laser combined with an SHG element (532 nm).

  Examples of the gas laser include a helium / cadmium laser (about 442 nm), an argon ion laser (about 514 nm), a helium neon laser (about 544 nm and 633 nm), and the like.

  LEDs having the same composition as LD are known, but various LEDs from blue to infrared have been put into practical use.

  As the exposure light source used in the present invention, each laser may be used alone, or may be used in combination as a multi-beam. In the case of an LD, for example, a beam composed of 10 luminous fluxes can be obtained by arranging 10 LDs. On the other hand, in the case of a helium neon laser, light emitted from the laser is divided into, for example, 10 light beams by a beam separator.

  The intensity change of the exposure light source can be directly modulated to change the value of the current flowing through each element in the case of an LD or LED. In the case of an LD, the intensity may be changed using an element such as an AOM (acousto-optic modulator). In the case of a gas laser, devices such as AOM and EOM (electro-optic modulator) are generally used.

  When an LED is used as the light source, a method of exposing the same pixel with a plurality of elements may be used as long as the amount of light is weak.

  Moreover, you may use an organic light emitting element as a light source which replaces these, These are described in Unexamined-Japanese-Patent No. 2000-258846 etc., for example.

  The emission wavelength of the light source can be preferably used in any wavelength region where the photosensitive material has sufficient sensitivity, but it has a sufficient sensitivity difference with other photosensitive layers in order to prevent color turbidity. It is preferable to use a region. Although it depends on the contrast of the photosensitive material, it is preferable that the common logarithm of the exposure amount has a sensitivity difference of 0.6 or more, preferably 1.0 or more. In addition, when the emission wavelength varies depending on the environmental conditions and operating conditions in which the light source is placed, it is theoretically preferable to match the peak wavelength of the spectral sensitivity. It is preferable to select the wavelength in consideration of the relationship. Examples thereof include JP-A-6-75342 and JP-A-2001-83663. Further, when not only the emission wavelength but also the emission intensity varies, it is preferable to select the emission wavelength in relation to the spectral sensitivity. Examples thereof include Japanese Patent Application Laid-Open No. 2002-72367 and Nikkei New Material September 1987. It is described on page 54 of the 14th of the month.

  In the present invention, the term area gradation image is used, but this is not expressed by the shading of the color of each pixel, but by the size of the area of the color developed at a specific density. It can be considered synonymous with halftone dots.

  Usually, in the case of area gradation exposure, the purpose can be achieved by causing Y, M, C, and black to be colored. More preferably, in order to identify that a single color such as M or C has developed in addition to black, it is preferable to perform exposure using different exposure amounts of three or more values. In printing, a special color plate may be used, but in order to reproduce this, it is preferable to perform exposure using different exposure values of four or more values.

  In the case of a laser light source, the beam diameter is preferably 25 μm or less, more preferably 6 to 22 μm. If it is smaller than 6 μm, it is preferable in terms of image quality, but adjustment is difficult or the processing speed decreases. On the other hand, if it is larger than 25 μm, unevenness increases and the sharpness of the image also deteriorates. By optimizing the beam diameter, high-definition images without unevenness can be written at high speed.

  In order to draw an image with such light, it is necessary to scan the silver halide color photosensitive material with a light beam. The silver halide color photosensitive material is wound around a cylindrical drum and rotated while rotating at high speed. A so-called cylindrical outer surface scanning method in which the light beam is moved in a direction perpendicular to the direction may be employed, and a so-called cylindrical inner surface scanning method in which a silver halide color photosensitive material is exposed in close contact with a cylindrical depression may be preferably used. A so-called plane scanning method may be employed in which the polyhedral mirror is rotated at a high speed, and the silver halide color photosensitive material conveyed thereby is exposed by moving the light beam perpendicular to the conveying direction. From the viewpoint of high image quality and obtaining a large image, the cylindrical outer surface scanning method is more preferably used.

  In order to perform exposure by the cylindrical outer surface scanning method, the silver halide color photosensitive material must be brought into close contact with the cylindrical drum accurately. In order to reliably perform this close contact, it is necessary to accurately align and transport. The silver halide color light-sensitive material used in the present invention can be preferably used because the surface on the side to be exposed (the side on which the silver halide emulsion layer is coated) can be more accurately aligned. From the same viewpoint, the support used for the silver halide color photographic material used in the present invention has an appropriate rigidity, and a Taber rigidity of 0.8 to 4.0 is preferable.

  The diameter of the exposure drum can be arbitrarily set according to the size of the silver halide color photosensitive material to be exposed. The number of rotations of the exposure drum can be arbitrarily set, but an appropriate number of rotations can be selected depending on the beam diameter of the laser beam, the energy intensity, the writing pattern, the sensitivity of the silver halide color photosensitive material, and the like. From the viewpoint of productivity, it is preferable that scanning exposure can be performed at a higher rotation speed. Specifically, 200 to 3000 rotations per minute is preferably used.

  The silver halide color photosensitive material can be fixed to the exposure drum by mechanical means, or a large number of fine holes that can be sucked on the drum surface are provided according to the size of the silver halide color photosensitive material. In addition, the silver halide color light-sensitive material can be attracted and adhered. Adhering the silver halide color photosensitive material to the exposure drum as much as possible is important to prevent troubles such as image unevenness.

  As an apparatus used for image formation, a method in which a plurality of photosensitive materials are set in advance and the photosensitive materials are appropriately selected and used can be preferably used. In this case, the two types of photosensitive materials can be, for example, photosensitive materials having different widths or photosensitive materials having different surface properties (unevenness of the support). The selection of the photosensitive material may be a method of setting using a switch of the image forming apparatus or the like, or setting information may be transmitted together with image data and selected based on the setting information. It can also be advantageously used to automatically select the optimum size of the photosensitive material according to the size of the image data. In special cases, the same type of photosensitive material can be loaded, and when one photosensitive material is used up, the other photosensitive material can be automatically used. This is advantageous because continuous unattended operation is possible. Can be used.

  Next, the development process will be described.
