Description

  The present invention relates to a silver halide photographic color light-sensitive material and an image forming method, and more particularly to a silver halide photographic color light-sensitive material and an image forming method suitable for color printing. In particular, a large number of prints can be produced in a short time. The present invention also relates to a silver halide photographic color light-sensitive material and an image forming method capable of high-quality printing with less printing unevenness and defects.

  In recent years, there has been a remarkable spread of digitization in the field of color printing using color photographic paper. For example, the digital exposure method using laser scanning exposure is an analog that directly prints with a color printer from a processed color negative film. Compared to the exposure method, it shows a dramatic increase in the penetration rate. Such a digital exposure method is characterized in that high image quality can be obtained by performing image processing, and plays an extremely important role in improving the quality of color prints using color photographic paper. In addition, with the rapid spread of digital cameras, it is also an important factor that simple and high-quality color prints can be obtained from these electronic recording media, and it is thought that these will lead to further dramatic spread.

  On the other hand, as a color printing method, technologies such as an ink jet method, a sublimation type method, and color xerography have advanced, and are being recognized as a color printing method, for example, to improve photographic image quality. Among these, the characteristics of the digital exposure method by laser scanning exposure using color photographic paper are high image quality, high productivity, and high image robustness. It is desired to provide a simpler and cheaper. In order to further improve the image quality of laser scanning exposure using color photographic paper, it is effective to increase the writing density of the image. In addition, if you can quickly perform from the exposure of color photographic paper to the end of processing, you will be able to return high-quality prints within a few minutes after receiving the digital camera recording medium at the store. Such speeding up also improves print productivity per unit time, and the superiority of color printing using color photographic paper increases. As described above, it is extremely important that the color photographic paper and the image forming method using the color photographic paper can quickly perform from the exposure to the end of processing.

Conventionally, studies have been made from various viewpoints so that the process from the exposure of color photographic paper to the end of processing can be performed quickly. However, most of these studies are related to shortening the processing time.
As a silver halide emulsion used for color photographic paper, a silver halide emulsion having a high silver chloride content is used because of a demand for rapid processability. The high silver chloride emulsion progresses rapidly, does not generate a development inhibitor such as Br ion or I ion during the development process, and does not accumulate in the developer, and thus is stable against variations in processing factors.

High sensitivity can be obtained by incorporating a phase having a high silver bromide content in various forms in an emulsion having a high silver chloride content (for example, Patent Documents 1 to 3). Further, Patent Documents 4 and 5 disclose that an emulsion containing I having a maximum concentration on the subsurface of a high silver chloride emulsion can provide an emulsion with high sensitivity and low illuminance failure. In the example of Patent Document 6, a specific compound is contained in a particle having an edge length of 0.218 μm that forms an I band at 93% of the particle formation, that is, a sphere equivalent diameter of about 0.27 μm. It has been disclosed that an emulsion excellent in temperature dependency and pressure property during failure and exposure can be obtained.
It is known to dope an iridium (Ir) complex in order to improve the high illuminance failure of the silver chloride emulsion and to obtain a high gradation even at high illuminance. For example, Patent Document 7 discloses that the problem of latent image sensitization is solved by providing a localized phase having a high silver bromide content and doping iridium therein. Patent Document 8 discloses a method for making high-intensity gradations hard by preparing an emulsion having a localized phase with a high silver bromide content. Patent Document 9 discloses an example of improving high-illuminance failure with a specific metal complex having an organic ligand.
However, neither of these teaches that streak-like unevenness caused by high-density and high-speed exposure and shortening the time from exposure to color development can be improved.

In color photographic paper for laser scanning exposure and an image forming method using the same, in order to achieve higher image quality, faster output, and higher productivity, high-density and high-speed exposure and exposure We eagerly studied how to shorten the time to color development.

We have made various studies to solve this problem, and formed a silver bromide-containing phase into a layer, a silver iodide-containing phase into a layer in a silver halide emulsion used for color photographic paper, or at least It has been found that streaky unevenness can be eliminated by including a hexacoordinate complex having Ir as a central metal having two different ligands in the same complex, and the present invention is made based on this finding.

According to the image forming method of the present invention, it is possible to form an image with high image quality quickly and with high productivity.

The present invention is described in detail below.
[Image formation method]
First, an image forming method according to the present invention will be described.
The image forming method of the present invention is characterized in that scanning exposure is performed at a sub-scanning conveyance speed of 90 mm / sec or more and a raster interval of 500 μsec or less, and color development is started within 12 seconds after the end of the scanning exposure. Here, the sub-scan refers to the main scanning for scanning exposure, which conveys the photosensitive material in the vertical direction and gives the photosensitive material two-dimensional exposure, and the raster interval is intermittent exposure in the sub-scanning conveying direction. It is the time interval of the light beam to be performed. That is, it means a time interval from when a certain pixel is exposed to when the next pixel adjacent in the sub-scan transport direction is exposed. The time from the end of scanning exposure to the start of color development is the latent image holding time from the time when a certain point on the photosensitive material is scanned and exposed until the same point is applied to the color developer. When the photosensitive material is conveyed by a sheet body and exposure processing is performed, the entire sheet body does not have to be the latent image holding time of the present invention, and one point to be exposed on the sheet body may satisfy the time of the present invention. .
An example of an image forming apparatus that exposes a photosensitive material will be specifically described below.

In the present invention, an image forming apparatus for exposing a photosensitive material is, for example, as shown in FIG.
An image forming apparatus 10 illustrated in FIG. 1 includes a scanner 12, an image processing apparatus 13, a printer 14, a processor 15, and a sorter 19. The printer 14 is a recording apparatus that exposes and records a photosensitive material using light beam scanning exposure, and is a cut sheet that is drawn and cut by a predetermined length from a long photosensitive material A wound in a roll shape. A photosensitive material (hereinafter also referred to as a sheet member) is conveyed to the exposure position, while the light beam L modulated in accordance with the image data supplied from the image processing device 13 is deflected in the main scanning direction and the main scanning is performed. The photosensitive material is scanned and conveyed in the sub-scanning direction orthogonal to the direction, and the photosensitive material is scanned and exposed by the light beam L to form an image.

  The printer 14 in the image forming apparatus 10 is connected to the image processing apparatus 13, and the image processing apparatus 13 is connected to the scanner 12. On the other hand, the processor 15 is connected adjacent to the printer 14 so as to receive the exposed photosensitive material unloaded from the printer 14. The image forming apparatus 10 includes a control unit (control unit) 34 that controls the overall operation of the image forming apparatus 10. The printer 14 is provided with a plurality of conveyance roller pairs for conveying the sheet member. The sheet body is conveyed by the conveyance roller pair at a preset conveyance speed (hereinafter also referred to as a first conveyance speed).

The scanner 12 photoelectrically reads the projection light of the image photographed on the film with an image sensor such as a CCD sensor, captures the image data (image data signal) of the film, and sends it to the image processing device 13.
The image processing device 13 performs predetermined image processing on the image data and sends it to the printer 14 as image data (exposure conditions) for image recording. The image processing apparatus 13 may be configured to send image data obtained by photographing with a digital still camera or the like to the printer 14.
The processor 15 performs predetermined development processing, drying processing, and the like on the sheet body (photosensitive material) on which the exposed latent image is recorded, thereby obtaining a print in which an image photographed on the sheet body is reproduced. The processor 15 is provided with a plurality of conveyance roller pairs for conveying the sheet member. Also in the processor 15, the sheet is conveyed at a preset conveyance speed (hereinafter also referred to as a second conveyance speed) by the conveyance roller pair, and the exposed sheet body is subjected to development processing.
The sorter 19 collects and collects sheets subjected to development processing, drying processing, and the like, for example, for each film.

  The exposure unit 26 is located upstream and downstream in the transport direction so as to sandwich an exposure unit 36 connected to the image processing apparatus 13 and an exposure position r for scanning and exposing the sheet member with the light beam L emitted from the exposure unit 36. Position detection that is provided between a pair of sub-scanning rollers 46 and 48 that conveys the sheet body at a predetermined speed to perform sub-scanning, and is positioned between the exposure position r and the sub-scanning roller pair 46. And a sensor 50.

  The exposure unit 36 is a known light beam scanning device that uses, for example, a light beam such as a laser beam as recording light, and each of red (R) exposure, green (G) exposure, and blue (B) exposure of the sheet member. A light source that emits a light beam L corresponding to the light source, and an AOM (acousto-optic modulator) that modulates the light beam L emitted from the light source according to image data after image processing supplied from the image processing device 13 Modulation means, an optical deflector such as a polygon mirror for deflecting the modulated light beam L in a direction (main scanning direction) orthogonal to the transport direction, and the light beam L deflected in the main scanning direction on the exposure position r It has a mirror for adjusting the optical path of an fθ (scanning) lens that forms an image at a predetermined position with a predetermined beam diameter.

Also, transport directions of PDP (plasma display) array, ELD (electroluminescent display) array, LED (light emitting diode) array, LCD (liquid crystal display) array, DMD (digital micromirror device, registered trademark) array, laser array, etc. Digital exposure means using various light emitting arrays or spatial modulation element arrays extending in the main scanning direction perpendicular to the main scanning direction may be used.
The main scanning width of the light beam L performed at the exposure position r of the exposure unit 36 is set so as to correspond to the width of the sheet member. The above operation of the exposure unit 36 is controlled by a control signal from the control unit 34.

The light beam L, which is recording light, is deflected in the main scanning direction (in FIG. 1, the direction perpendicular to the paper surface), while the sheet member is conveyed by the sub-scanning roller pairs 46 and 48, and thus is modulated according to the image data. The sheet body is two-dimensionally scanned and exposed by the light beam L, and an image is recorded. The effect of the present invention can be obtained when the speed conveyed by the sub-scanning roller pair is 90 mm / sec or more.
Instead of the sub-scanning roller pairs 46 and 48, a scanning conveyance mechanism that uses an exposure drum that conveys the sheet body while holding the sheet at the exposure position r, and two nip rollers that contact the exposure drum across the exposure position r. May be used. The configuration is not particularly limited as long as an image is recorded on the sheet body being conveyed by performing scanning recording at least in the main scanning direction orthogonal to the conveyance direction of the sheet body.

  The sub-scan receiving unit 28 includes a plurality of roller pairs that support a leading end portion of a sheet that is conveyed during recording in the exposure unit 26 and protrudes from the exposure unit 26, and includes, for example, three roller pairs. . Each roller pair includes a driving roller and a nip roller capable of releasing the nip that moves freely with respect to the driving roller. The sheet body is conveyed by the roller pair at the same speed as the conveyance speed of the sub-scanning roller pair.

  At the timing when the leading and trailing ends of the paper pass through the driving roller portion during exposure recording, the nip roller is controlled so as not to be separated from the driving roller and nip the sheet member. That is, after the front end of the sheet member passes through the exposure point downstream roller pair in a separated state, the nip roller of the exposure point downstream roller pair comes into contact with the driving roller to nip and convey the sheet member. Also, immediately before the rear end of the sheet member passes through the roller pair upstream of the exposure point, the nip of the roller pair upstream of the exposure point is released, and the sheet member is nipped and conveyed only by the roller pair downstream of the exposure point. To do. This is because, during exposure recording of the sheet body, minute vibrations occur due to the leading or trailing end of the sheet body passing through the roller section while the nip roller pair remains in the nip state, and the position at which the sheet body is exposed. This is to prevent the occurrence of misalignment and exposure unevenness. Of course, the operation of the sub-scan receiving unit 28 is controlled by a control signal supplied from the control unit 34.

  In the present invention, the sub-scanning conveyance speed needs to be 90 mm / sec or more (preferably 90 mm / sec or more and 300 mm / sec or less), and is preferably 95 mm / sec or more and 200 mm / sec or less. The raster interval needs to be 500 μsec or less (preferably 500 μsec or less and 150 μsec or more), and preferably 200 μsec or more and 450 μsec or less. The time from the end of scanning exposure to the start of color development needs to be within 12 sec (preferably 1 sec to 12 sec), preferably within 10 sec (preferably 1 sec to 10 sec), preferably within 8 sec (preferably 1 sec to 8 sec) is more preferable, and 1 sec to 5 sec is most preferable.

[Silver halide emulsion]
Next, the silver halide emulsion relating to the present invention will be explained.
The silver halide emulsion of the present invention contains specific silver halide grains. The particle shape of this particle is not particularly limited, but is substantially a cubic or tetradecahedral crystal particle having {100} faces (these particles may have rounded vertices and higher order faces). ), Octahedral crystal grains, and the main surface is preferably composed of tabular grains having an aspect ratio of 3 or more and comprising {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 the particle. In particular, cubic or tetrahedral crystal particles are more preferable.

The silver chloride content must be 90 mol% or more, and the silver chloride content is preferably 95 mol% or more, more preferably 98 mol% or more. When the silver halide emulsion of the present invention has a silver bromide-containing phase, the silver bromide content needs to be 0.1 to 4 mol%, preferably 0.5 to 2 mol%. When the silver halide emulsion of the present invention has a silver iodide-containing phase, the silver iodide content must be 0.02 to 1 mol%, preferably 0.05 to 0.50 mol%. More preferably, it is 07-0.40 mol%.
The specific silver halide grains of the present invention are preferably silver iodobromochloride grains having both a silver bromide-containing phase and a silver iodide-containing phase, and particularly preferably silver iodobromochloride grains having the above-mentioned halogen composition.

  The specific silver halide grains in the silver halide emulsion of the present invention have a silver bromide-containing phase and / or a silver iodide-containing phase. Here, the silver bromide or silver iodide-containing phase means a portion where the concentration of silver bromide or silver iodide is higher than the surroundings. The halogen composition of the silver bromide-containing phase or silver iodide-containing phase and its surroundings may change continuously or may change sharply. Such a silver bromide or silver iodide-containing phase may form a layer having a substantially constant width at a certain portion in the grain, or may be a maximum point having no spread. The local silver bromide content of the silver bromide-containing phase is preferably 3 mol% or more, more preferably 5 to 40 mol%, and most preferably 5 to 25 mol%. The local silver iodide content of the silver iodide-containing phase is preferably 0.3 mol% or more, more preferably 0.5 to 8 mol%, and more preferably 1 to 5 mol%. Most preferred. Further, a plurality of such silver bromide or silver iodide-containing phases may be provided in the form of layers in each grain, and the silver bromide or silver iodide content may be different.

  It is important that the silver bromide-containing phase or the silver iodide-containing phase of the silver halide emulsion of the present invention is layered so as to surround each grain. In one preferred embodiment, the silver bromide-containing phase or the silver iodide-containing phase formed in layers so as to surround the grains has a uniform concentration distribution in the circumferential direction of the grains in each phase. However, in the silver bromide-containing phase or silver iodide-containing phase that are layered so as to surround the grain, the maximum or minimum point of the silver bromide or silver iodide concentration exists in the circumferential direction of the grain, and the concentration distribution You may have. For example, when a silver bromide-containing phase or silver iodide-containing phase is formed in a layer so as to surround the grain in the vicinity of the grain surface, the silver bromide or silver iodide concentration at the grain corner or edge is different from the main surface. There is a case. In addition to the silver bromide-containing phase and the silver iodide-containing phase that are layered so as to surround the grain, the silver bromide-containing phase that is completely isolated in a specific part of the surface of the grain and does not surround the grain Alternatively, there may be a silver iodide containing phase.

  When the silver halide emulsion of the present invention contains a silver bromide-containing phase, the silver bromide-containing phase is preferably formed in a layered manner so as to have a silver bromide concentration maximum inside the grain. Further, when the silver halide emulsion of the present invention contains a silver iodide-containing phase, the silver iodide-containing phase is preferably formed in a layered manner so as to have a silver iodide concentration maximum on the surface of the grain. Such a silver bromide-containing phase or silver iodide-containing phase is composed of a silver amount of 3% to 30% of the grain volume in order to increase the local concentration with a smaller silver bromide or silver iodide content. It is preferable that the silver content is 3% or more and 15% or less.

  The silver halide emulsion of the present invention preferably contains both a silver bromide-containing phase and a silver iodide-containing phase. In this case, the silver bromide-containing phase and the silver iodide-containing phase may be at the same place or different places in the grain, but it is preferable that the silver bromide-containing phase and the silver iodide-containing phase are in different places from the viewpoint of facilitating control of grain formation. Further, the silver bromide-containing phase may contain silver iodide, and conversely, the silver iodide-containing phase may contain silver bromide. In general, iodide added during the formation of high silver chloride grains tends to ooze out on the grain surface than bromide, so the silver iodide-containing phase tends to be formed near the grain surface. Therefore, when the silver bromide-containing phase and the silver iodide-containing phase are at different locations in the grain, the silver bromide-containing phase is preferably formed inside the silver iodide-containing phase. In such a case, another silver bromide-containing phase may be provided further outside the silver iodide-containing phase near the grain surface.

  It is preferable to concentrate the functions of the silver bromide-containing phase and silver iodide-containing phase that control photographic action close to the surface in the grain. Therefore, the silver bromide-containing phase and the silver iodide-containing phase are preferably adjacent to each other. From these points, the silver bromide-containing phase is formed at any of the positions of 50% to 100% of the grain volume as measured from the inside, and the silver iodide-containing phase is any of the positions at 85% to 100% of the grain volume. It is preferable to form it. Further, the silver bromide-containing phase is formed at any position from 70% to 95% of the grain volume, and the silver iodide-containing phase is further formed at any position from 90% to 100% of the grain volume. preferable.

  When the silver halide emulsion of the present invention has a silver bromide-containing phase, another preferred embodiment of the silver bromide-containing phase has a silver bromide content of 0. 0 in a depth within 20 nm from the grain surface. It is a silver halide emulsion having a region of 5 to 20 mol%. It is preferable to have a silver bromide-containing phase within 10 nm from the grain surface, preferably a silver bromide-containing phase having a silver bromide content of 0.5 to 10 mol%, and 0.5 to 5 mol More preferably, it has a silver bromide-containing phase.

The laser beams of the three colors are moved by the polygon mirror in the main scanning direction and the direction perpendicular to the scanning direction so that the sample can be sequentially scanned and exposed. Variation in the amount of light due to the temperature of the semiconductor laser is suppressed by keeping the temperature constant using a Peltier element. The effective beam diameter was 80 μm, the scanning pitch was 42.3 μm (600 dpi), and the exposure time per pixel was 7 to 8 × 10 ⁻⁸ seconds. The temperature of the semiconductor laser was made constant by using a Peltier element in order to suppress the change in light quantity due to temperature. The exposure was performed in a temperature-controlled room under a low temperature environment of 15 ° C./55% RH under the condition that the roller that transports the sample to the post-exposure processing unit is condensed and the condensation is uneven.
