Description

  The present invention relates to a single color silver halide color photosensitive material that can be developed by an automatic processor for silver salt color photography, and an image forming method thereof. More particularly, the present invention relates to a silver halide color light-sensitive material for outputting a proof for a monochrome image and an image forming method, which can use a direct digital color proof system of a silver salt color system.

  Silver halide light-sensitive materials are actively used today because of their high sensitivity, excellent color reproducibility, and suitability for continuous processing. In the conventional method of printing an image taken with a color negative using an optical system, if the conditions are set in advance, the exposure conditions are easily adjusted from the result of measuring the density of the color negative, and the image quality is excellent in full color with a single exposure. It was possible to obtain a continuous print image and had high productivity. Recently, it is also used for digital image formation in which the amount of light of an exposure light source is modulated from image data taken with a digital camera to a laser, LED, or the like, thereby forming an image. Even in such digital image exposure, normally, modulated three-color B, G, and R light is mixed and an image is formed by one scanning exposure, which has the same high productivity as the conventional one. It was.

  In addition, it is known that a recording material using a silver halide light-sensitive material has little noise particularly at a low density, and has a feature that a very smooth gradation reproduction is possible. When has a sufficient gradation reproduction capacity, it has a feature that it is particularly excellent in the depiction of highlights. From these characteristics, the silver halide light-sensitive material is widely used not only in the field of photography but also in the field of printing, in the field of so-called proofing for checking the state of the finished printed matter in the middle of printing.

  In the field of proofing, each image of yellow (Y), magenta (M), and cyan (C) is output by outputting an image edited on a computer to a printing film, and separating and exposing the developed film as appropriate. An image is formed, and an image of the final printed matter is formed on color photographic paper, thereby determining the suitability of the layout and color of the final printed matter.

  Recently, a method of directly outputting an image edited on a computer to a printing plate, so-called Computer to Plate (CTP), has gradually become widespread. In such a case, the data on the computer is not passed through the film. It has been desired to obtain a color image directly.

  For such purposes, 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. There is a drawback, and the cost is low, and the method with excellent productivity has the disadvantage that the image quality is inferior. A system using a silver halide light-sensitive material can form a high-quality image such as an accurate halftone image due to excellent sharpness and the like, while being capable of continuous processing as described above. In addition, high productivity can be realized because images can be simultaneously written in a plurality of color image forming units.

  In recent years, so-called digitization has progressed in the field of printing, and the demand for obtaining images directly from computer data has increased. For the reasons described above, silver halide light-sensitive materials are advantageously used in this field for proof applications. Yes. For example, a technique relating to a silver halide photographic material exposed using an exposure apparatus equipped with a specific laser light source unit for the purpose of producing a color proof, and a cartridge for storing the silver halide photographic material is disclosed. (For example, refer to Patent Document 1). Further, a technique relating to an image forming method in which a specific silver halide photographic light-sensitive material is exposed with a specific exposure light source is disclosed (for example, see Patent Document 2). Furthermore, a technique is disclosed in which a silver halide photographic photosensitive sheet is fixed to the outer peripheral surface of a drum, the drum is rotated at high speed, and exposure is performed by an optical head that irradiates a plurality of beams (see, for example, Patent Document 3). . In addition, high-definition color proofs are produced by increasing the number of halftone dots per unit area when scanning a silver halide photographic material wrapped around the drum surface with a laser to form a halftone image. (For example, refer to Patent Document 4). Further, a technique relating to a method for producing a direct digital color proof using a silver halide color light-sensitive material, characterized by using a negative emulsion, is disclosed (for example, see Patent Documents 5 and 6).

  Now, many of the printed materials are substantially monochrome images such as a map on which only contour lines are drawn, and a paper surface composed of a single color of a comic magazine. In such printed matter, when the proof is output, there is a problem that the use of a silver salt type color proof as described above is slightly expensive, though it is convenient. Therefore, in the case of outputting a proof for a printed matter substantially containing only a monochrome image by the silver halide photography method, development of a low-cost dedicated paper has been desired.

  On the other hand, in the development processing system for silver halide photography, the color system is currently the mainstream, and so-called monochrome photography has almost no need. However, some professional photographers and photographic enthusiasts have a strong popularity, but due to the widespread use of development processing systems, they require much more time and processing costs than color photography. Therefore, black-and-white photographic light-sensitive materials that can be processed by a developing machine for color photographic processing have been proposed (see, for example, Patent Documents 7, 8, and 9). In addition, a photosensitive material that can be processed by a color developing machine as a film for a monochrome movie has been proposed (for example, see Patent Document 10).

  However, these are intended to produce substantially pure black-and-white photographs, and since a single photosensitive material can be processed by a plurality of processing systems, it does not become pure black-and-white due to variations in processing conditions. Had a problem.

  In addition, as a light-sensitive material capable of obtaining a black and white image through color processing, three emulsion layers of yellow, magenta and cyan are substantially different among emulsion layers having four different spectral sensitivities. Emulsions each containing a dye-forming coupler, the remaining emulsion layer containing two dye-forming couplers of yellow and magenta, and a layer containing two colors of yellow and magenta Has been disclosed in which an emulsion having the same spectral sensitivity is added to an emulsion layer containing the cyan dye-forming coupler and added (for example, see Patent Document 11). In addition to yellow, magenta, and cyan monochromatic colors, black color is developed by combining cyan and red complementary colors, so that the monochrome density and black density can be output at optimum densities. It is. By adding the same emulsion to the cyan image forming layer and the yellow and magenta coupler-containing image forming layer, a black image can be formed as a result of exposure to the emulsion to develop a color. This is only YMC image information. Since the black image can be obtained from the other black image information, and the black hue cannot be arbitrarily changed, the configuration of the present invention is different.

Therefore, the present inventor has invented a light-sensitive material dedicated to a single color image, which can be used as it is, an apparatus of a direct digital color proof system based on a silver salt color photographic system.

Another preferred form is a solid particulate compound having a fluorescent whitening effect.

  In the present invention, in particular, in the invention that does not define the exposure light source, any known exposure light source can be preferably used, and a laser or LED is preferably used.

  As the laser, a semiconductor laser (hereinafter referred to as LD) is preferably used because it is compact and the life of the light source is long. 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 LDs 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.

  In the invention that does not particularly specify the method of changing the intensity of the exposure light source, in the case of LD, LED, etc., direct modulation that changes the value of the current flowing through each element can be performed. The intensity may be changed using an element such as an AOM (acousto-optic modulator). In the case of a gas laser, a device such as AOM or EOM (electro-optic modulator) is 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 if the amount of light is weak.

  It is preferable that the exposure light sources constitute light source blocks of three or more wavelengths different from each other, each mounted in a holder, and equipped with at least eight for each wavelength. It is preferably 16 pieces, more preferably 32 pieces. Each light source is preferably arranged in a line in the sub-scanning direction, that is, perpendicular to the rotation direction of the drum, in other words, parallel to the rotation axis of the rotation drum.

  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 developing colors of Y, M, C, and black. 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 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. For this to be done accurately, it needs to be accurately aligned and transported. The silver halide color light-sensitive material used in the present invention can be preferably used because it can be more accurately aligned when the surface to be exposed is wound outward. From the same viewpoint, the support used for the silver halide color light-sensitive material used in the present invention preferably has an appropriate rigidity and a Taber rigidity of 0.8 to 4.0.

  The diameter of the rotating drum can be arbitrarily set according to the size of the silver halide color photosensitive material to be exposed. The number of revolutions of the drum can also be set arbitrarily, but an appropriate number of revolutions can be selected according to the beam diameter of the laser beam, the energy intensity, the writing pattern and the sensitivity of the photosensitive material. From the viewpoint of productivity, it is preferable that scanning exposure can be performed at a higher speed, but specifically, 100 to 3000 rotations per minute is preferably used. More preferably, it is 200 to 2000 rotations.

  After the light-sensitive material according to the present invention is exposed, if the rear end of the light-sensitive material that has been exposed and transported to an automatic developing machine for development processing does not completely enter the developing bath, the exposure is performed. However, it is preferable that the photosensitive material be developed as soon as possible because of the stability of the latent image formed on the exposed silver halide. The time from the end of exposure until the leading edge of the photosensitive material enters the developing tank is preferably from 10 seconds to 10 minutes, particularly preferably from 15 seconds to 5 minutes.

  Further, the time from when the front end of the exposed silver halide color light-sensitive material is immersed in the developer until the rear end is immersed is preferably shorter, and is preferably within 5 minutes.

Further, from the viewpoint of the stability of the white background of the output image and the reduction of the replenishment amount of the processing liquid, the ratio of the washing time or the stabilization processing time to the total processing time excluding the drying step is preferably 40% or more. 50% or more is more preferable.

  The temperature of the color developer is preferably higher from the standpoint of simply increasing the density, but there is also a problem of the stability of the developer itself, which causes deterioration in image stability. Therefore, the temperature of the developer is preferably 40 ° C. or lower, more preferably 38 ° C. or lower. Further, the temperature of the bleach-fixing solution is also preferable in that it simply increases the bleach-fixing ability and improves the white background, but it is preferably 43 ° C. or less from the problem of the preservability of the bleach-fixing solution itself, like the developer. More preferably, it is 40 degrees C or less.

  In the present invention, it is essential that the temperature of the water washing or stabilizing solution can be maintained at 40 ° C. or higher in the first tank, but it is preferable that the temperature can be maintained at 40 ° C. or higher in the second and subsequent tanks. . Particularly preferably, all the water washing or stabilization treatment tanks can be kept at 40 ° C. or higher.

  Further, the number of tanks for the water washing or stabilization treatment is preferably 4 or more in order to achieve both good image formation and white background and low replenishment treatment.

In the processing of the silver halide color light-sensitive material according to the present invention, the color developer, the bleach-fixing solution, the water washing or the stabilizing solution are replenished, respectively, and the total amount of the liquid that overflows and becomes a waste solution is as follows. From the standpoint of waste liquid processing and the like, it is preferably 700 ml or less per 1 m ^{2 of the} silver halide color photosensitive material. More preferably, it is 500 ml or less.

The replenishing amount of the water washing or stabilizing solution is preferably 350 ml or less per 1 m ^{2 of the} silver halide color light-sensitive material. More preferably, it is 250 ml or less.

  In the process of washing with water or stabilizing tanks having 4 or more tanks, it is preferable to replenish each tank individually to become waste liquid, but this is not effective in reducing the replenishment amount. Therefore, it is preferable to use a so-called counter current system in which the replenisher enters the last tank, sequentially overflows to the previous tank, and overflows from the first tank as waste liquid.

  As a development processing apparatus used for the development processing of the silver halide color photosensitive material according to the present invention, a processing tank is formed in a slit shape, a processing liquid is supplied to the processing tank and a photosensitive material is conveyed, or a processing liquid. A spray method for spraying, a web method by contact with a carrier impregnated with a treatment liquid, a method using a viscous treatment liquid, and the like can also be used. Another preferred treatment form is to add a treatment agent in the form of a tablet as a replenishment method, which is the method described in the published technical report 94-16935.

  The drying process is not limited as long as the photosensitive material immersed in the processing solution is dried and output. However, the drying process applies hot air of 50 ° C. or higher, a flat surface, or a heater on a roller. The method of contacting and drying can be preferably used.

  In the conveyance of the photosensitive material in the automatic developing machine, a roller transport type in which the photosensitive material is conveyed by being sandwiched between opposed rollers driven in each processing tank is generally used. An endless belt method may be used.

  In the transition from one tank to the next, a semicircular guide made of plastic or Teflon (registered trademark) with low slip resistance on the surface is arranged, which allows U A method of turning and transporting the photosensitive material is also generally used. Further, in the drying process, particularly in the case of an automatic developing machine for a photosensitive material having a large size of A3 or larger, the photosensitive material is conveyed by driven opposed rollers provided at the entrance and exit portions of the photosensitive material. In the case of the wind drying method, generally, a plurality of elongated bars such as piano wires are arranged on the upper and lower surfaces or the lower surface of the photosensitive material inside the unit, and the photosensitive material is designed to slide there. All of these guides are arranged in parallel to the conveyance direction of the photosensitive material. However, it is preferable to arrange the guides at a slight angle in the conveyance direction so that the photosensitive material can be conveyed more smoothly. A preferred angle is 3 ° or more and 20 ° or less. More preferably, it is 3 ° or more and 10 ° or less. As the direction in which the angle is given, an arrangement is preferred in which each of them faces outward from the center in the transport direction.

  The results are shown in Table 11.

  As is apparent from Table 11, Sample 1-5 coated with colloidal silver is more excellent in fine line reproducibility.

Example 5
Sample No. 1 of Example 1 101, 1-1, the silver halide color photosensitive material (monochrome) sample No. 1-6 (invention) was produced.

  Sample No. produced 1-6 (present invention) and sample Nos. For 1-3 (invention), the same exposure and processing as in Example 2 were performed. Further, the exposure processing was performed by replacing the Y value in the color correction table with 0.5 and 1.3 times. In the cartoon image, the density of a solid colored portion capable of taking a circular area having a diameter of 8 mm was measured. For the measurement, an X-rite 530 type spectrocolorimetric densitometer manufactured by X-rite was used, and Status T was used for the spectral characteristics. The Y density, M density, and C density were evaluated at the standard color correction value and 0.8 times and 1.3 times the color correction value.

  The results are shown in Table 13.

  As can be seen from Table 13, the overall density is simply increased or decreased in Sample 1-3, but it can be seen that Sample 1-6 can arbitrarily adjust the hue of the monochrome image. It can be seen that the configuration of the sample 1-6 is more preferable in that the finished product can be easily simulated as well as the proof.
