Description

  The present invention relates to a novel silver halide color photographic light-sensitive material, and in particular, to a silver halide color photographic light-sensitive material that is excellent in image depiction of a character image composed of a black and white image in transmission viewing and at a higher density. Is.

  In recent years, display advertisements using large color photographic prints, ink jet prints, and the like are increasing. These advertisement display prints can be displayed not only in bright places due to reflection / transmission of image irradiation light, but also in dark rooms, indoors, or outdoors at night. The advertisement display print needs to provide a vivid image for its use, and generally has a higher image density than a general color print. In spite of the fact that the convenience of inkjet printing has been increasing in advertising display applications, silver salt color photographic prints are still dominant in the advertising industry due to their excellent image stability. It is needless to say that image display stability is necessary because advertisement display prints can be used outdoors, indoors, and indoors, and are constantly irradiated with light from a fluorescent lamp or the like. Therefore, in the advertising industry, it is necessary to provide a more excellent image stability which is a characteristic of silver salt color photographic prints.

  On the other hand, in advertising display applications, a method of exposing an image recorded on a negative optically on a photosensitive material to be printed has been generally used, but recently, the image is once converted into digital information. After that, the image is imaged on a CRT (cathode ray tube), further imaged on a photosensitive material and exposed, or the laser beam intensity is changed based on digital information and the exposure is performed by scanning. Has increased. Image information converted into digital data through a scanner, etc. can be edited and processed on a computer, and data such as characters and illustrations can be added relatively easily. For example, photographs of people, landscapes, animals, etc. Opportunities are increasing for handling images in which image data (hereinafter referred to as scene images) based on shooting data and character images (particularly fine and small black character images) are mixed. For this reason, in image output based on digital data, it is necessary to satisfy the two requirements simultaneously that a scene image is more natural and a character image is reproduced without blurring.

  Many types of digital exposure apparatuses that perform exposure based on image information that has been converted into digital data are now on sale, and many new digital exposure apparatuses have been researched and developed along with advances in exposure light sources and control devices. Yes. Among these digital exposure apparatuses, an apparatus using a light source having a sharp light source wavelength distribution such as a laser or LED as an exposure light source is becoming mainstream. However, the types of lasers and LEDs mounted in various digital exposure apparatuses are not unified, and the exposure wavelength is often different for each exposure apparatus. Furthermore, even if the same exposure light source is used, it is often different in various points such as the overlapping ratio of exposure beams, the exposure time interval between adjacent pixels, the exposure time per pixel, and the exposure intensity. For this reason, when the exposure apparatus is different, a phenomenon that the print quality to be reproduced fluctuates easily occurs, and the improvement has been desired.

  In addition, a scanning exposure method using a light beam is known as one of the most frequently used exposure methods among digital exposure methods. As one of means for achieving high speed in this method, a method using a plurality of exposure light sources of the same color (hereinafter referred to as “array exposure method”) is known. However, when the array exposure method is used, there is a phenomenon that it takes time and effort to cancel the exposure streaks as compared with the exposure method using a single light source, and improvement thereof has been desired. In general, the array block exposes a plurality of pixels at a time. For this reason, there are cases where adjacent pixels are exposed at the same time in the array block and cases where exposure is performed at different timings with the conveyance of the photosensitive material or the movement of the exposure head in the middle. For this reason, when the exposure time interval between adjacent pixels is different, a photosensitive material having a small density change and a stable characteristic has been demanded in order to facilitate the operation of canceling the exposure streak.

  This problem can be reduced by optimizing the photosensitive material for each exposure device or for each usage environment, but there are many types of digital exposure devices on the market and will continue to increase in the future. This is not a realistic response. Under such circumstances, no matter what type of exposure apparatus is used or the usage environment changes, the character outline is sharp and blurring is small, and the light and dark stripes of the image resulting from scanning exposure are not noticeable. A silver halide color photographic light-sensitive material from which a print can be obtained and an image forming method thereof have been desired.

  On the other hand, in the large-format color print material for transparent viewing for advertisement display, there are many subjects in which the image to be handled has a uniform density centering on the article, and furthermore, the high density represented by the black color that is dominant in the transparent viewing material Reproduction is very important, and the product value depends greatly on the blackness (maximum density) and the black color (tone). Therefore, for black, preferable reproduction is required under various light boxes that are actually displayed.

  In light of the above problems, advertising color print materials that are reproduced at a high density including a digital exposure method have been disclosed (see, for example, Patent Documents 1 and 2). However, there is no mention of character quality (outline, blur) and black quality in the digital exposure method. Further, a technique that enables reproduction of preferable character quality with various digital exposure apparatuses is disclosed in detail (for example, see Patent Document 3), but no material for transparent viewing is mentioned. In fact, according to the results of the study by the present inventors, it has been found that the requirements for the transparent viewing material are different from those proposed above.

When each of the proposed methods described above is applied to a color print material for transparent viewing for advertisement display obtained by exposing and developing with a digital exposure apparatus, as described above, black reproduction is not sufficient, and However, it is difficult to say that the reproducibility of character quality, which is very frequently used for advertising purposes, is still satisfactory, and there is a need for further improvements.

One feature of the silver halide color photographic light-sensitive material of the present invention is that the exposure is performed at an exposure time of 10 ⁻¹⁰ seconds to 10 ⁻³ seconds per pixel.

  In general, when image information is digitized and handled, an original image is divided into fine grids, and density information is digitized for each grid. In the present invention, the minimum unit when this original image is handled in a grid is defined as one pixel. Therefore, the exposure time per pixel can be considered as the time during which the intensity of the light beam or the irradiation time is controlled based on the digital data for one pixel.

All of the color images obtained in this way are ΔLogE that is the horizontal axis from the exposure point required to obtain the minimum transmission density + 0.1 density obtained from the density (D) -exposure quantity (LogE) characteristic curve described above. It is preferable that the transmission density at the 1.5 exposure point is 3.0 or more. This is particularly effective in giving high image quality reproducibility, especially in high density areas, by making high image density particularly black reproduction and extremely frequently used for advertising purposes. It is.

In order to form a photographic image using the silver halide color photographic light-sensitive material of the present invention (hereinafter also simply referred to as light-sensitive material), the exposure time per pixel is 10 ⁻¹⁰ seconds or more based on digital image data, It is preferable to use an exposure method that results in 10 ⁻³ seconds or less. Among them, the scanning exposure method using a light beam can be preferably used from the viewpoint of obtaining high-quality prints while maintaining high print productivity.

  The scanning exposure using a light beam preferably used in the present invention is usually a linear exposure using a light beam (raster exposure: main scanning) and a relative movement of a photosensitive material in a direction perpendicular to the linear exposure direction ( In general, it is performed by a combination of sub-scanning. For example, a photosensitive material is fixed to the outer periphery or inner periphery of a cylindrical drum, and the main scanning is performed by rotating the drum while irradiating a light beam, and at the same time, the light source is moved perpendicularly to the rotation direction of the drum. In this way, the sub-scanning method (drum method) and the rotating polygon mirror are irradiated with a light beam to scan the reflected beam horizontally with the rotating surface of the polygon mirror (main scanning), and the photosensitive material A method of performing sub-scanning (polygon method) by transporting perpendicularly to the rotation surface is often used. In the drum system, the main scanning speed can be adjusted by adjusting the drum diameter and the drum rotation speed, and the sub-scanning speed can be adjusted by adjusting the moving speed of the light source.

  The overlap between the rasters of the light beams can be appropriately controlled by adjusting the timing of the main scanning speed and the sub scanning speed described above. In addition, when an exposure head in which light sources are arranged in an array is used, it is possible to control the overlap between light beams by appropriately adjusting the intervals between the individual light sources.

There may only be regions of different composition. Further, the composition may change continuously or discontinuously. The portion where silver bromide is present at a high concentration is particularly preferably the surface of silver halide grains or the apex of crystal grains.

<< Characteristic Evaluation of Samples 501 to 506 >>
(Measurement of wavelength difference ΔλH)
In accordance with the method of Evaluation A described in Example 1, the Latin filter No. Using 99 (manufactured by Eastman Kodak Co.), exposure to a single color of green light was performed, followed by color development.

  Next, for the obtained magenta color image, a spectral spectrum at 400 to 700 nm is obtained using a 330 type self-recording spectrophotometer manufactured by Hitachi, Ltd., and the maximum density is obtained in the maximum absorption wavelength region (λmax) in the magenta color image. Is normalized to the minimum density +1.0, and when this is taken as 100%, the wavelength difference ΔλH between the wavelength λL on the long-wave end side and the wavelength λL ′ on the short-wave end side at the 50% concentration, that is, the half-value concentration was obtained. .

(Evaluation C)
Similar to Evaluation B described in Example 1, a calibration operation was performed to create an LUT, and then a print image including 50%, 1.0%, and 0.1% gray or black solid portions was output.

The observation light source becomes magenta and green, and they look completely different, both of which have low points. On the other hand, Samples 504, 505, and 506 that satisfy the conditions defined in the present invention have good blackness, and the two colors of observation light sources are close to black, and the points are high because there is no sense of incongruity.

  As is clear from the results shown in Table 9, if all of Dym, Dmm, and Dcm have 3.4 or more, 1.0% and 0.1% black appear to have a high density. However, in actuality, it greatly depends on ΔλH of the magenta coloring dye, and a satisfactory black margin is not obtained in the sample 602 that deviates from the conditions specified in the present invention. The color tone is magenta and green with two types of observation light sources, and the point is low in the sense that it looks completely different. On the other hand, the samples 604, 605, and 606 that satisfy the conditions specified in the present invention all have a good black margin, and the black color with the two types of observation light sources is close, and there is no sense of incongruity. it was high. Furthermore, in the sample of the present invention, there was no scanning streak at 50% gray and no rough feeling, and the connection seemed natural.
