2. Description of the Related Art In a silver halide photographic light-sensitive material obtained by a subtractive color method (hereinafter sometimes simply referred to as "light-sensitive material"), a color image is formed by three primary colors of yellow, magenta and cyan. In a color photographic method using a current p-phenylenediamine-based color developing agent, an acylacetic acid anilide-based compound is used as a yellow coupler. However, the hue of the yellow dye obtained from these couplers is reddish due to poor absorption on the long wavelength side of the absorption, and it is difficult to obtain a yellow hue of high purity, and the molecular extinction coefficient of the dye is also high. Is small, requires a large amount of coupler and silver halide to obtain a desired color density, and has a problem that the sharpness of the obtained color image may be reduced due to an increase in the thickness of the photosensitive material. Was. Further, the dye is easily decomposed under high-temperature and high-humidity conditions or under light irradiation conditions, and there is a problem in image storability after development processing.

In order to solve these problems, an acyl group and an anilide group have been improved. Recently, a coupler obtained by improving a conventional acyl acetate anilide system is described in JP-A-4-218,042. 1-alkylcyclopropanecarbonylacetic acid anilide type compound

The light-sensitive material of the present invention is suitable for a scanning exposure method using a cathode ray (CRT) in addition to being used for a printing system using a normal negative printer. A cathode ray tube exposure apparatus is simpler, more compact, and lower in cost than an apparatus using a laser. Further, adjustment of the optical axis and color is also easy. For the cathode ray tube used for image exposure, various luminous bodies that emit light in a spectral region are used as necessary. For example, any one of a red light emitter, a green light emitter, and a blue light emitter, or a mixture of two or more thereof is used. The spectral region is not limited to the above red, green, and blue, and a phosphor that emits light in a yellow, orange, purple, or infrared region is also used. In particular, a cathode ray tube which emits white light by mixing these light emitters is often used.

When the photosensitive material has a plurality of photosensitive layers having different spectral sensitivity distributions and the cathode tube also has a phosphor which emits light in a plurality of spectral regions, a plurality of colors are exposed at a time, that is, the cathode ray is exposed. A plurality of color image signals may be input to the tube to emit light from the tube surface. A method of sequentially inputting image signals for each color, sequentially emitting light of each color, and exposing through a film that cuts a color other than that color (plane sequential exposure)

A digital scanning exposure method using monochromatic high-density light is preferably used. In order to make the system compact and inexpensive, it is preferable to use a semiconductor laser, a semiconductor laser or a second harmonic generation light source (SHG) in which a solid-state laser is combined with a nonlinear optical crystal. Particularly, in order to design an apparatus that is compact, inexpensive, and has a long life and high stability, it is preferable to use a semiconductor laser, and it is preferable to use a semiconductor laser as at least one of the exposure light sources.

When such a scanning exposure light source is used,
The spectral sensitivity maximum wavelength of the photosensitive material of the present invention depends on the scanning used.
It can be set arbitrarily according to the wavelength of the exposure light source.

Preferred scanning exposure methods applicable to the present invention are described in detail in the publications listed in the above table. Further, for processing the light-sensitive material of the present invention, JP-A-2-207250, page 26, lower right column, line 1 to page 34, upper right column, line 9 and JP-A-4-97355, page 5 upper left column The processing materials and processing methods described in the 17th line to the 20th line on the lower right column on page 18 can be preferably applied. As the preservative used in this developer, compounds described in the publications listed in the above table are preferably used.

The present invention is preferably applied to a photosensitive material having suitability for rapid processing. The color development time refers to the time from when the photosensitive material enters the color developing solution to when it enters the bleach-fix solution in the next processing step. For example, when processing is performed by an automatic developing machine or the like, the time during which the photosensitive material is immersed in the color developing solution (so-called in-solution time) and the time when the photosensitive material leaves the color developing solution and is bleached and fixed in the next processing step The sum of the time during which it is transported in the air toward the bath (the so-called air time) is referred to as the color development time. Similarly, the bleach-fixing time refers to the time from when the photosensitive material enters the bleach-fixing solution to when it enters the next washing or stabilizing bath. The term “washing or stabilizing time” refers to the time during which the photosensitive material is in the washing or stabilizing solution and is in the solution for the drying step (so-called in-solution time).

In the present invention, the color development time is preferably 60 seconds or less, more preferably 50 seconds or less and 6 seconds or more.
More preferably, it is 30 seconds or less and 6 seconds or more. Similarly, the bleach-fixing time is preferably 60 seconds or less, more preferably 5 seconds or less.
It is 6 seconds or more, preferably 0 second or less, more preferably 30 seconds or less. The washing or stabilization time is preferably 15 minutes.
The time is 0 second or less, more preferably 130 seconds or less and 6 seconds or more.

As a method of developing the photosensitive material of the present invention after exposure, there are a conventional method of developing with a developer containing an alkali agent and a developing agent, and a method of incorporating a developing agent into the photosensitive material and containing no developing agent. In addition to a wet method such as a method of developing with an activator liquid, a thermal developing method without using a processing liquid can be used. In particular, since the activator method does not contain a developing agent in the processing solution, it is easy to manage and handle the processing solution, and is a preferable method from the viewpoint of environmental conservation because it has a small load when processing the waste liquid. In the activator method, examples of the developing agent or its precursor incorporated in the photosensitive material include, for example, JP-A-8-234.

In particular, it is preferable to use this method for the activator method. Specifically, Japanese Patent Application Laid-Open
An image forming method using an activator liquid containing hydrogen peroxide described in JP-A-297354 and JP-A-9-152699 is preferably used. In the activator method, after processing with an activator solution, usually a desilvering process is performed, but in an image amplification processing method using a low silver content photosensitive material,
The desilvering process can be omitted, and a simple method such as washing with water or stabilizing process can be performed. Further, in a method of reading image information from a photosensitive material by a scanner or the like, a processing mode that does not require desilvering processing can be adopted even when a photosensitive material having a high silver content such as a photosensitive material for photography is used.

As the activator solution, desilvering solution (bleaching / fixing solution), washing and stabilizing solution used in the present invention, known materials and processing methods can be used. Preferably, Research Disclosure Item 36544

As a result, light color mixing is removed, and color reproducibility is significantly improved. In the present invention, as described in European Patent Nos. EP0789270A1 and EP0789480A1, before applying image information, a yellow microdot pattern may be pre-exposed in advance to control copying.

The light-sensitive material of the present invention can be preferably applied as a light-sensitive material for an advanced photo system having a magnetic recording layer. Further, the light-sensitive material of the present invention can be preferably applied to a system for heat development using a small amount of water or a complete dry system for heat development without using any water.

The obtained sample solutions 101 to 106 were applied to a thickness of 1
The sample was put in a quartz cell having a size of 1 cm, and a visible absorption spectrum was measured with an ultraviolet-visible spectrophotometer manufactured by Shimadzu Corporation. As a parameter representing the absorption edge of the dye on the long wavelength side, the wavelength (λ (0.05)) at A = 0.05 on the long wavelength side when the absorbance (A) at the maximum absorption wavelength λmax is 1 was read, and ΔS
(0.05) = λmax−λ (0.05), Δ
S (0.05) / nm was determined. Table 3 shows the results.

[0151]

[Table 3]

From Table 3, it can be seen that the dye obtained from the dye-forming coupler in the present invention has a smaller ΔS (0.05) and a better skirt on the long-wave side than the dye obtained from the dye-forming coupler for comparison. . This is because, in the silver halide photographic light-sensitive material using the coupler, since the proportion of reddish contained in the yellow dye is small, the color reproducibility of the obtained image, particularly the reproducibility of lemon yellow color is improved.

The average exposure time per pixel was 8 × 10 ^-8 seconds. The temperature of the semiconductor laser was kept constant by using a Peltier element in order to suppress a change in light amount due to temperature.

Each of the exposed samples was developed using the above-mentioned running processing solution, and the same evaluation as that for the photosensitive materials performed in Comparative Examples 3 and 4 and Examples 5 to 8 was performed. As a result, it was confirmed that all of the dye-forming couplers of the present invention had high coloring properties and were excellent in hue and fastness.
