The layer to which the compound represented by the formula (I) is added may be a silver halide emulsion layer or a layer containing no silver halide emulsion, but is a silver halide emulsion layer. Is preferred in terms of a silver complex formed by the compound being chemically adsorbed to a silver halide emulsion.

The amount of the compound added is preferably 0.3 mg / m ² or more (preferably 0.3 mg / m ² or more and 3 mg / m ² or less) in view of the necessary amount for coating the surface of the silver halide grains. , more preferably from 0.5 mg / m ² or more (preferably 0.5 mg / m ² or more 2 mg / m ² or less), more preferably 0.6 mg / m ² or more (preferably 0.6 mg / m ² or more 1.5 mg / m ² or less, most preferably 0.70 mg / m ² or more (preferably 0.70 mg / m ² )
mg / m ² or more and 1.25 mg / m ² or less).

The silver halide grains in the silver halide emulsion used in the present invention are preferably cubic or tetradecahedral crystal grains having substantially {100} faces (these grains have a rounded apex and a higher height). Or octahedral crystal grains, or 50 of total projected area
% Or more are tabular grains having an aspect ratio of 2 or more composed of {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 a particle. In the present invention, a cubic or tabular grain having a {100} plane as a principal plane or a tabular grain having a {111} plane as a principal plane is preferably applied.

As the silver halide emulsion used in the present invention, silver iodobromide, silver chloroiodobromide emulsion and the like are used. From the viewpoint of rapid processing, a salt having a silver chloride content of 95 mol% or more is used. A silver iodide or silver chlorobromoiodide emulsion is preferred, and a silver chloroiodide or silver chlorobromoiodide emulsion having a silver chloride content of 98 mol% or more is more preferred. Among such silver halide emulsions, 0.05 to 0.75 mol%, more preferably 0.1 to 0.7 mol%, per mol of total silver is added to the shell portion of silver halide grains.
Those having a silver iodochloride phase of 0.40 mol% are also preferred because they can provide high sensitivity and are excellent in high illuminance exposure suitability. Further, those having a silver bromide localized phase of 0.2 to 5 mol%, more preferably 0.5 to 3 mol%, based on the total silver mole on the surface of silver halide grains can provide high sensitivity, and It is particularly preferable because photographic performance can be stabilized.

When the emulsion used in the present invention contains silver iodide, the iodide ion is introduced by adding a solution of an iodide salt alone or by adding a silver salt solution and a high chloride salt solution. At the same time, an iodide salt solution may be added. In the latter case, the iodide salt solution and the high chloride salt solution may be added separately or as a mixed solution of the iodide salt and the high chloride salt.
The iodide salt is added in the form of a soluble salt, such as an alkali or alkaline earth iodide salt. Alternatively, U.S. Pat.
Iodide can also be introduced by cleaving iodide ions from organic molecules described in the specification of 389,508. Further, fine silver iodide grains can be used as another iodide ion source.

The addition of the iodide salt solution may be performed intensively at one time of the grain formation, or may be performed over a certain period of time. The position at which iodide ions are introduced into a high chloride emulsion is limited in order to obtain an emulsion having high sensitivity and low fogging. As the iodide ion is introduced into the emulsion grains, the increase in sensitivity is smaller. Therefore, the addition of the iodide salt solution is preferably effected from outside 50% of the particle volume, more preferably from outside 70%, most preferably from outside 80%. Also, the addition of the iodide salt solution is preferably terminated within 98% of the particle volume, most preferably within 96% of the particle volume. When the addition of the iodide salt solution is completed slightly inward from the grain surface, an emulsion with higher sensitivity and lower fogging can be obtained.

The distribution of iodide ion concentration in the depth direction in the grain is determined by etching / TOF-SIMS (Time of Fligh).
The measurement can be performed by, for example, a TRIF II TOF-SIMS manufactured by PhiEvans Co., Ltd. by the t-Secondary Ion Mass Spectrometry method. The TOF-SIMS method is specifically described in “Surface Analysis Technology Selection Secondary Ion Mass Spectrometry” edited by The Surface Science Society of Japan, Maruzen Co., Ltd. (1999). When the emulsion grains are analyzed by the etching / TOF-SIMS method, even if the addition of the iodide salt solution is completed inside the grains, it can be analyzed that iodide ions are exuding toward the grain surface. When the emulsion used in the present invention contains silver iodide, analysis by etching / TOF-SIMS reveals that the concentration of iodide ion has a maximum at the grain surface and the iodide ion concentration decreases toward the inside. Is preferred.

As a binder or protective colloid that can be used in the light-sensitive material of the present invention, it is advantageous to use gelatin, but other hydrophilic colloids can be used alone or together with gelatin.

In the present invention, in order to prevent various molds and bacteria that propagate in the hydrophilic colloid layer and deteriorate the image, a bactericidal / fungicide as described in JP-A-63-271247 is added. Is preferred. Further, the coating pH of the photosensitive material is preferably from 4.0 to 7.0, and more preferably from 4.0 to 6.5.

^-5 to ¹ g / m ² , preferably 1 × 10 ^-4 to 1 × 10 ^-1 g
/ M ² , more preferably 1 × 10 ⁻³ to 1 × 10 ⁻² g / m ^2.
It is. These fluorine atom-containing surfactants may be used alone or in combination with other conventionally known surfactants, but are preferably used in combination with other conventionally known surfactants.

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. Various light emitters that emit light in a spectral region are used as necessary for a cathode ray tube used for image exposure. 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 that emits light in a plurality of spectral regions, a plurality of colors are exposed at a time, that is, A plurality of color image signals may be input to the cathode ray tube to emit light from the tube surface. A method of sequentially inputting image signals for each color to sequentially emit light of each color, and exposing through a film that cuts a color other than that color (plane sequential exposure) may be employed. However, since a high-resolution cathode ray tube can be used, it is preferable for high image quality.

The photosensitive material of the present invention is a gas laser, a light emitting diode, a semiconductor laser, a semiconductor laser or a second harmonic emission light source (SHG) in which a solid laser using a semiconductor laser as an excitation light source is combined with a nonlinear optical crystal.
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 using such a scanning exposure light source,
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.

If the size is defined as the exposure time, the preferred exposure

Below.

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, the lower right column of page 26, lower right column of page 26 to the upper right column of page 34 of JP-A-2-207250, and the upper left column of page 5 of JP-A-4-97355 can be used. The processing materials and processing methods described in line 17 to page 20, lower right column, line 20 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 light-sensitive materials 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 submerged time) and the time when the photosensitive material leaves the color developing solution and is bleach-fixed in the next processing step The sum of the time during which it is transported in the air toward the bath (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 submerged time).

In the case of performing rapid processing 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, and particularly preferably 20 seconds or less and 6 seconds or more. Similarly, the bleach-fixing time is preferably 60 seconds or less, more preferably 50 seconds or less and 6 seconds or more, and particularly preferably 30 seconds or less and 6 seconds or more. The washing or stabilization time is preferably 150 seconds or less, more preferably 130 seconds or less.
It is 6 seconds or less for seconds or less.

As a method of developing the photosensitive material of the present invention after exposure, there are a conventional method of developing with a developing solution containing an alkali agent and a developing agent, and a developing solution containing a developing agent in the photosensitive material and containing no developing agent. In addition to a wet method such as a method of developing with an activator solution such as a method described above, a thermal developing method without using a processing solution 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.
No. 388, No. 9-152686, No. 9-152693
And hydrazine-type compounds described in JP-A Nos. 9-218814 and 9-160193.

Further, a developing method in which the amount of silver applied to the light-sensitive material is reduced and image amplification processing (intensification processing) using hydrogen peroxide is preferably used. 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 solution 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 in which image information is read 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 processing materials and processing methods can be used. Preferably, Research Disclosure Item 36544
(September 1994) Pages 536 to 541, JP-A-8
-234388 can be used.

When exposing the light-sensitive material of the present invention to a printer, it is preferable to use a band stop filter described in US Pat. No. 4,880,726. 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 used in combination with an exposure and development system described in the following known materials. An automatic printing and developing system described in JP-A-10-333253; a photosensitive material transporting device described in JP-A-2000-10206; a recording system including an image reading device described in JP-A-11-21512; -88619 and JP-A-10-202
